Spare Onboard Charger Power Cables
The charging cord should have no higher gauge than 14AWG with a NEMA 5-15P (US) to IEC320 C13 output plug rated for 15A; the onboard charger draws 11-12A at 120V AC (and half the amps at ~220V). A shorter cable can be more efficient by offering less resistance. Any cable rated below this specification will heat up and deteriorate so would be unsafe.
Longer (25+ft) cables should be bought in a lower gauge (thicker wire) like 12AWG. Or, if 25+ft needs to be made from two cables, make sure that most of the run is a 12AWG cable and only use 14AWG for a short section at the end (3-6ft).
15 vs. 25 feet at 12 amps (max pull in the Zero manual) is a 0.76% vs.1.27% voltage drop over distance respectively. A single use socket (no other attached devices - as recommended in the Zero manual) should work. Even assuming max pull at 15 amps (120v breaker/socket) it is 0.95% vs. 1.58%; either way it is over 110v over the distance, which is normal for the residential circuit of that type.
Do not use a retractable extension cord reel! Unless it is completely extended, the cord will not dissipate heat properly.
12V Electrical System
Zero S/DS/SR/DSR models have an accessory power circuit, ending in plugs under the tank plastics in front of the area reserved for the tank bin or power/charge tank, behind the front wheel. They can be accessed by hand without removing plastics but are easier with plastics removed. Both plugs are fed power from the same 10-amp circuit.
All 2013+ models have a Sumitomo power connector which is weather sealed. 2014+ models also include a standard SAE connector in the same area on the same circuit and fuse.
The 12v system on a Zero is very fault tolerant. It operates at a very consistent 14 volts, which provides up to 140W of power available on the accessory circuit, and 300W total. Some owners have used increased size fuses such as 12.5 or 15 amp for even more accessory power.
The wattage pulled by the accessory power has a negligible, almost immeasurable affect on range. Even at the maximum 140 watt output over 2 hours of straight riding, the 12v accessories would use 0.28 kWh of the total capacity of the battery, which for a ride under 2 hours is about 2-2.5% of the total power available. For reference, a heated jacket at full power will typically draw 90W, greater than the stock headlamp at 60W. The impact on the battery is greater if making a very long, slow use of the battery (say, under 35mph for at least 4 hours).
Zero's 12v accessories will plug directly into the Sumitomo connector.

The SAE connector is more common for third party accessories and can be easily adapted to other plugs (such as coaxial for heated gear) very easily.

Heated handgrips and heated seats were offered from 2013-2014 but have since been discontinued. The handle bar changes in 2015 made the handgrips non-transferrable.
Aerostitch noted some interesting details while installing these heated grips:
How to tie into +12v and bypass the fuses
- Remove the seat
- The fuse box will be under the left side of the Y-arm under the seat that connects the frame's tail to the crossmember around the battery.
- Remove the bolt on the left that holds the fuse box in place.
- This will allow the box to swing towards you and out from under the frame.
- On top of the fuse box are a bunch of blue connectors.
- They're the female side of spade connectors, covered by a rubber boot.
- The male side comes out of the top of the fuse box.
- Pick a connector and pull the blue boot straight up and off.
- Underneath, you'll see the male connector, with a small hole in the end.
- Connect your circuit's wire.
- If you're daring, you can try to thread your connector wire through this hole.
- You might instead strip off an inch or so of the wire from the horn, make a loop, and drape it around the male connector.
- Twist, wrap, tape or solder your loop once it's around the connector so it's reasonably tight.
- Replace the female connector in the blue boot back onto the male connector.
- Push hard so it goes all the way down and presses the wire loop down against the top of the fuse box.
- Test your new circuit/load.
- Apply electrical tape as you see fit.
- Replace the left bolt in the fuse box.
- Replace the seat.
- Test your new circuit/load again.

Zero S/DS/SR/DSR plastics are all interchangeable, aside from DS/DSR plastics being a different shape around the thighs (to allow for an easy transition to/from a standing position).
Zero doesn't make this clear on their website, but you can order any plastics that they offer through the dealer network - so, any color that has been offered for a model-year is probably in stock and can be shipped. The default tank plastics are the cheapest ($100 for a tank), the Power Tank plastics are slightly more expensive, and Charge Tank plastics are closer to a few hundred dollars. Tank plastics exchange is very quick, along with the front fender. The tail plastics can be bought with the tank plastics but the tail plastics swap process is more involved.
The front fender plastics only apply to S/SR/FXS models - DS/DSR/FX models have a 19-inch front wheel which does not accommodate it.
Splitting Up Tank Plastics
The centerpiece of the tank plastics is plastic welded with retaining lock washers through/around holes in the side pieces. They can be detached either with very focused heat application (a soldering iron works; a hot air gun will be less precise) or just taking a pair of pliers and carefully twisting each weld back and forth until it deteriorates and can be broken off. The centerpiece you remove will no longer be joinable the same way, but you can take a fresh one and make plastic welds to join it to the side pieces.
Get a professional to do it if you're not very patient, unless you have experience working vinyl. The compound curves of the tank plastics are not too easy to wrap with.
Luggage Rack Installation
OEM Top Rack
Zero OEM Top Box Rack Kit 10-06921 $150 USD on Zero website or $200 USD in 2016 dealer parts catalog.
- Adapted from this forum thread: Zero top rack and GIVI case install.
- This process takes about 15 minutes and is very easy.
- Remove the seat.
- Install the rubber cap on the tab under the plate.
- Pull the seat off and fit the rack over the bike frame.
- Install two 4mm socket head bolts through the frame holes.
- Replace the seat and tighten the T-45 Torx bolts (MY2015+) or 5mm socket head bolts (MY2013/MY2014; extras are provided) back in through the rear rack frame.
- Once the top rack is installed, the bolts holding the seat on are load-bearing.
- If the tab under the tail rack does not directly contact the tail plastics while unloaded, going over bumps at speed can wear on the mounting bolts over time and might break them. Fixing a cushioned (rubbery) spacer underneath it will dampen this dynamic load.
- If you need to remove the seat, take off the top case or remove any heavy contents to avoid stressing the rack over time.
- Side racks (both OEM and Happy Trails) are both installed in a way that somewhat stabilize the dynamic load on the top rack, but it's still fundamentally vulnerable to a lever effect on the bolts holding it down.
- Plate Adapter Compatibility
- The Givi M5 adapter does not fit the Zero factory rack without having made some hardware modifications to the plate.
- Non-Givi adapters will likely require similar customizations unless they are made for the same fastener geometry.
- The plate is made of steel so make sure to coat any exposed surfaces from drilling with paint etc to minimize corrosion.
Givi Monokey adapter plate E251
- To install any Givi box get the universal Monokey (part E251) top case adapter and mount it using four 5mm socket head bolts and 10mm locknuts with clamps that will fit almost any rack.
- The clamps are not needed for the Zero OEM top rack, just the square washers.
- There's some leeway in how far forward or back to place the adapter on the plate.
- It helps to use some Blue Loctite threadlocker and corrosion inhibitor on the screws and bolts used for the adapter, since these get heavily weathered from the wheel below and then the moisture sticks around.
- It helps to use the clamps so that they alternate direction and hold the adapter firmly in the lateral and forward-to-back directions.
- The cover plate includes four PH1 screws and also two much smaller PH1 screws. The smaller screws seem to be free spinning and the threads do not engage when installed, so a work-around is to stuff some plastic bag material or other filler into the plastic column underneath in the mounting plate where each fastener should attach to. This seems like an oversight by Givi and it is not mentioned anywhere in the instruction sheet.
OEM Side Racks
This process is a little more complicated. The rack kit comes with reasonably good instructions so for now this only addresses the complications to be aware of:
- The lower mounts are a pair of brackets that bolt to the inside of the frame where the passenger pegs are installed.
- There is very little clearance in this area, because it faces the motor.
- A telescoping ratcheting wrench or a small open ended socket wrench will be necessary to tighten the bolts.
- Removing the lower side plastics yields some clearance from the front for working with these bolts using a flat wrench.
- Do not fully tighten these bracket mounts until the entire assembly is in place, and then tighten them evenly.
- The assembly that holds the turn signals will be projected rearwards to clear the cases.
- This requires some work with the wiring to re-run them through the new bracket and is slightly awkward but can be finished with a little patience.
- The rubber bumpers needed to dampen side case vibration might fall out if you ride without the cases.
- Maybe apply a little rubber glue or such to hold them in place if this is a concern.
OEM Crash Bars
The police models (SP/DSP) include some broad crash bars. The width is about 7 inches on the top half, but they taper to the bottom so lean angle is not affected (see photos).
Zero does not list all drop bar options on their website, but dealers can request them by part number.
|Police Drop Bars
|10-08062XX||Dual Sport Drop Bars||$250|
|10-0806203||Frame Protection Bar Accessories Kit, Non-Police, 13-16 MY
|10-08028||Zero FX Drop Bars||$175|
- Install Variations
- MY 15+, the frame is predrilled to mount them, but the lower mount varies slightly per model year and may require modification to the belly pan.
- MY 14, the belly pan required drilling, and use of Rivnuts. Zero was not cooperative in acquiring, but parts from a downconverted SP were found.
- Ensure you have all the parts:
- Two side bars, one per side.
- One crossmember piece.
- Two shoulder brackets, one per side.
- Two heavy bolts for joining the crossmember to the bars through the shoulder brackets.
- Shoulder mount bolts: 4 M5 bolts of 20mm overall length with a 5mm long shoulder that is 6mm diameter.
- Lower mount bolts: 4 M6 bolts of perhaps 15mm length.
- Allen wrenches for M5 and M6 bolts (depends on what is chosen).
- Wrench for hex head M10x70mm stay bolts.
- (Pre-2015) Create frame holes for the upper and lower pair of bolts on each side of the frame.
- Installing rivet nuts as Zero started doing for 2015+ frames is a good practice.
- Zero chose M5 rivet nuts with a 5mm deep, 6mm diameter shoulder space above it. M6 might be a more robust choice.
- One pair goes into the rear/top of the angled bar before it comes to the frame shoulder, 30mm between hole centers.
- One pair goes into the side of the belly pan / bash plate. The DS' metal bash plate is more suitable for this.
- (2015+) Remove the plastic threaded cover inserts in the pair of holes on each side of the bash plate.
- You may need to remove the plate to rotate them out from the inside. Remount after.
- Install the small shoulder brackets on each side of the frame shoulder area, using the pair of holes to anchor the brackets.
- Do not tighten the bolts until all pieces are in place.
- Detach the horn and the bracket holding it and set it aside.
- You may relocate it closer into the front of the frame or move it to the side (no recommendation here).
- For the DS/DSR, the front fender will interfere with this and the next step. Detach it and set it aside.
- Take the cross member and place it between shoulder brackets.
- Hold the cross member in place by running the M10x70mm bolts through the main holes.
- Attach each crash guard bar to the M10 bolt and fasten the lower end to the side of the bash plate using a pair of bolts.
- Tighten the bolts in concert.
- Once both crash guard bars are fastened tightly, check and tighten the bolts holding the small shoulder brackets.
- For the DS/DSR, replace the front fender if you removed it before.
- (Pre-2015) Create frame holes for the upper and lower pair of bolts on each side of the frame.
Notes for 2016 DSR: The skidplate included in the 10-08062XX kit is redundant it is the exact same one already on a factory new DSR, with plastic plugs in the threaded inserts that need removed.
Helmet Lock Removal
Steps (MY2016 DSR)
- Remove the front fender
- Remove the cowl
- Loosen the bolt holding the ABS module in place from underneath, located above where the front fender was. The ABS module appears to be mounted on two or three of these bolts with rubber vibration isolation around the bolts. When this bottom bolt is free the ABS module can be rotated from within the under-cowl area for better access to the innards.
- Drop the flasher relay and accessory power plugs out of the way and, using a mirror, locate the bolt holding the helmet lock in place.
- Loosen the bolts holding the helmet lock in place. The left one is more easily accessible. Clearances for the right bolt are very tight and it may not be possible to rotate any tool to loosen the right bolt. After removing the left bolt, it can be possible to loosen the right bolt by holding the right bolt in place and rotating the helmet lock itself.
- (Optional) Chargetank Bracket Installation
- Reinstall the bottom bolt for the ABS unit bottom bolt, cowl, and front fender.
- (Advanced) Relocate the helmet lock
Chargetank Inlet Bracket
Bracket p/n 12-08047XX (formerly p/n 12-0804713) special order $106 USD
Steps (Used MY2016 DSR)
- Remove helmet lock
- Thread ground strap onto studded bracket and reinstall through frame. Suggest to use a short section of painters masking tape stuck around the thread of the studs to itself like a "flag" to keep the ground strap secure in its position until the studded bracket can be fully seated to where the helmet lock used to be secured; the "flag" can be pulled up through the bolt holes in the frame and removed when ready.
- ?? Take a guess. There's a bag of parts. FIXME: Describe what all the parts are and how they should be installed.
- With the inlet bracket installed, two of the top mounting holes on the bracket are meant to be fastened through the chargetank cowl and into the inlet bracket. You only need to mount the J1772 inlet itself to the bracket using the rear top two locations. The front top two locations will be further secured when the chargetank cowl is mounted.
Handlebars and Controls
Any aftermarket "stalk" mirrors or mirror extenders with the Yamaha/Ducati-style left-hand-threaded left mirror will fit.
The bolt/thread specification appears to be M10 with x 1.25 pitch, left-hand-threaded on the left side.
- 7/8" bar-end mirrors are generally compatible, including offset and fold-away models, but the rubber grips must be cut to give access for installation.
- 7/8" bar-end mirrors are likewise compatible. The bar ends are sealed with a round nub at the end. Pull the nubs off with pliers to remove. Installation is straightforward and doesn't deviate from the manufacturer's instructions.
- With Cycra Hand Guards
- Mirrors of this type (Cheap Amazon Mirrors) work very well by putting them outboard of the hand guards and securing with a longer screw (M8-1.25 x 70mm, SS philips head from Home Depot will do).
Zero S/DS/SR/DSR models have 1⅛" diameter (28mm), 2" length clamps which are common dimensions so can be supported by most vendors.
Nothing confirmed yet; one hack is to rotate the handlebars (or rotate a compatible replacement set) to get the desired height/angle.
Options for disabling ABS, particularly for offroading with downhill runs:
- Per the official manual, you can disable ABS once per active session.
- Place the kickstand down.
- Turn off the Motor Stop switch.
- Key the bike on.
- On the dash, press and hold both the ADJ and MODE buttons simultaneously.
- Wait about 4 seconds until the ABS light starts flashing slowly, then release both.
- Restore by getting the contactor to open, by keying the bike off without being plugged in.
- Remove power to the ABS pump (works basically permanently).
- Remove the ABS pump fuse under the seat.
- Disconnect the power connector to the pump itself.
- Cover the connector to prevent electrical problems, and tape it to prevent wear from shaking while riding.

Brake Lever Regens before Pad Contact
This is a recipe to allow better regen and coasting control on a Zero.
- While using Custom Mode, touch the brake lever gently to get the Custom max regen brake regen level without using the brake pads.
- This exercises more control over when to coast and when to slow down, particularly when using the economizing hack of 0% Custom max regen and 100% Custom max regen brake.
- The brake light switch on the side of the right hand switch assembly also activates the Custom max regen brake regen level.
- The brake lever at rest normally presses it down (i.e., when you're not squeezing the lever to stop).
- Squeezing the lever increases the distance between it and the switch and the switch gets released to activate the brake light.
- The brake lever depresses the hydraulic cylinder from the front via a push pin, which has an adjustment knob to change the brake lever distance.
- See the Front Brake Lever Adjuster section of the Official Owners Manual for a basic diagram and description.
- Adjust the front brake lever to release the brake light switch before the push pin contacts the hydraulic actuating cylinder.
- The pressure from the master cylinder is what supports the lever to keep the brake light switch pressed down.
- So, when shortening the push pin, the lever becomes more wobbly and more likely to accidentally trigger the brake light switch due to vibrations or wind.
- Also, the brake lever needs to be squeezed closer to the throttle.
- Don't shorten the push pin so much that the lever contacts the throttle too easily, limiting full braking power.
- With good brakes that should not happen, but if you have air in the system your front brake might be squishier than normal and you might not be able to pressurize it fully, thus you may not stop as fast as it would be possible otherwise.
- If your disk brake doesn't engage immediately upon contact with the hydraulic actuating cylinder, you can set the regenerative brake activation immediately after the lever contacts the cylinder.
- Other preventative measures:
- Using a longer or stronger spring.
- Placing something in the spring slot to (slightly) shorten it.
- Increase the friction between the brake lever and its seat by coating the contact areas with paint, etc.
- (Optional) 7/64 wrench for the brake lever adjustment knob.
- Small flat-blade screwdriver for the brake light switch set screw.
- (Optional) Light thread-lock compound (Blue Loctite, say).
- Adjust the brake lever adjustment knob to engage the brake as loose as seems comfortable.
- Then, adjust the set screw to activate the brake light switch earlier in the engagement pull.
- Or, per this forum thread for an FX, add a 0.5mm thick washer to the brake line switch.
- Test ride to calibrate this.
- Ensure it is safe to engage and release.
- Ensure it is not difficult to fully engage the brake pads themselves.
- (Optional) use thread-lock compound to ensure the set screws stay where desired.
See Re: Solved: Full regen instead of 50% for the thought process framing this documentation.
See also the third-party brake light modifications that help alert drivers when using regen.
- Zero provides versions of Cycra handguards customized to fit around the Zero brake lever geometry.
- The brake lever customization is why the part numbers vary from 2013-2014 models and 2015+ models - the front brake system and reservoir differ.
- Fitment for DS/DSR/FX/FXR are identical. S/SR fitment is likely.
- Cycra equivalent parts:
- Cycra Black Anodized CRM Bar Set with Plastic Bumpers (requires bending for right side)
- Cycra Black Anodized Handguard CRM Clamp Set Oversize 1-1/8 Bars
- Cycra Bar Ends
- Cycra Black Handguard Shields (multiple colors available)
- Cap Screw Corrosion
- Both Cycra and Zero's customized handguard kits come with socket cap bolts that corrode too easily.
- Replace them with equivalent stainless socket cap screws for better weather resistance.

- For left and right assemblies each, align the plastic end cover with matching bracket.
- Affix with self-tapping PH2 (approx 12mm length) fasteners
- For each of the six PH2 self-tapping screws, insert one screw through washer then plastic hand guard and into hole on aluminum bracket.
- Remove 6mm hex bit bolts from handlebar mounting insert hardware as shipped.
- Insert bolt into end of assembled guard bracket, then a washer (thick for throttle / right side and thin for non-throttle / left side), an appropriate expansion insert for the diameter of your handlebar tube, and a cone nut.
- Do not tighten too much, but be sure this is snug fitting so that friction allows the 6mm bolt to be tightened without supporting the pieces that will be free-standing in the tube.
- If this is too lose, you would insert the assembly into the tube and not be able to tighten.
- If it is too tight, the cone nut will expand the mounting insert and it won't fit into the tube.
- Using a channel locks pliers or maybe just pull with your hands, remove plastic plugs from handlebar ends.
- Insert the appropriate handlebar guard assembly that has been prepared.
- While holding the handlebar guard assembly true and flush with the end of the handlebar, tighten the 6mm hex bit bolt until the assembly is secure.
- Lay out the handlebar clamp assembly: 4mm hex bit bolts (4 qty) in tapered cap end bracket, tapered bracket clamp, bushing, 13mm hex socket bolt. R is right side and L is left side.
- The manufacturer imprint should read upside-down (this is obvious when you notice the taper of the clamp and how the Zero handlebars are a wider diameter at the fork clamps and tapering down to a smaller diameter outward towards the handlebar grips).
- Set aside the bushing and 13mm hex socket bolt for the final step.
- Install the handlebar clamp bracket to the handlebar tube and tighten the 4mm hex bit bolts.
- Use a 16mm socket for reference of the gap between the fork handlebar clamps and the handlebar guard clamps.
- Don't worry about trying to make the open threaded end line up with the slot in the handlebar assembly, the assembly will be bent into place to meet the clamp later.
- Try to install the clamp so it is at a reasonable angle (for this install it kind of points towards the middle of the height of the dashboard display).
- Grab that bushing and 13mm hex socket bolt from earlier.
- Install the bolt through slot in the handlebar guard assembly, then the bushing, and bend the whole contraption into place so you can get threaded into the clamp bracket.
- Note: To avoid cross-threading the clamp bracket, take your time and use your hands to get it started.
- Note: For this install, it was attempted with the bushing to the inside and to the outside of the two metal brackets versus the head of the bolt; Bushing sandwiched between the two metal brackets seems to be the best but you may want to throw a washer on the head of the bolt and perhaps some Loctite on the threads. (Needs to be verified against the original instructions if anyone has these?)
- Done! Tighten everything again to your liking.

Zero handlebars are 7/8" near the controls and grips, so any handgrips for that size should work.
Crampbusters are a very good and cheap solution ($10 USD) for grip ergonomics if the existing grips are acceptable but your hands get tired in traffic or on the highway.
Zero handlebars are 1 1/8" through the risers, so many handlebars will be suitable to adapt (e.g. ProTaper).
- Confirmed fit
- ProTaper EVO Adventure Bars
- Remove the handlebar clamps.
- Remove the controls from the stock bars.
- Take measurements from the stock handlebars for what hole pattern the controls mount to.
- You will have to drill one hole to mount the throttle and potentially three holes for the switch gear.
- Install the controls over the new set of bars.
- Mount the handlebars with the clamps. Make sure to use thread-locker fluid to hold them in place once the positioning is verified.
- Generally, a throttle lock is a cheap way to get a basic cruise control mechanism.
- Electric motorcycles never stall and have a broad torque curve, so throttle locks are very effective despite their simplicity.
- A Zero with a cruise control will speed up and slow down to maintain an overall constant power/torque output, which makes range and power consumption much more predictable.
- 5% range gain can be had just from removing wrist adjustments from the throttle.
- Holding a throttle steady is a source of fatigue, so a lock helps minimize that.
- Any traction loss with an electric motor while using a throttle lock is dangerous.
- The rear wheel could spin up rapidly, faster than one's reaction time.
- This wastes precious seconds when the bike could lose stability and go down, when the throttle should be immediately eased off and balance recentered.
- For this reason, using a throttle lock should be limited to highway stretches with good visibility and no traction risks.
- Make sure, otherwise, that you can release the throttle lock very quickly and easily to avoid an emergency.
- Tested Options
- Brian Rice found and installed an Atlas throttle lock which seems to suit the Zero well, particularly because it avoids taking up valuable handgrip space and has a generic fitment. The Magura throttle's space for the Atlas to fit into is extremely narrow, though.
- Atlas nicely posted a comparison chart illustrating how different throttle lock mechanism approaches have tradeoffs.
- Go Cruise throttle lock is generic and easy to use, but does take up space on the inside of the throttle grip, which can make the throttle and mode switches harder to use.
- Kaoko throttle locks operate as bar ends with a dial and are good if the bike fit is confirmed, which Zero does not have.
Not available yet; see Crampbusters or Throttle Locks above.

The picture shows the TruckLite 7" LED Headlight.
It is necessary to replace or remove the existing Zero headlamp housing. This also means adding another possibility to mount the new headlamp.
In this case, as shown in the picture, I chose the Highsider headlamp bracket set Z-STYLE.
- Headlamp Housing
- You will also need a cover/encasing for the 7" headlamp.
- This is what I did: I bought a cheap 7" British Style Cafe Racer Flat Black Headlight and replaced the old lamp with the LED.
I only removed some parts of the original bracket, because it also holds the dashboard in place.
With changes to the mounting bracket or some DIY, it should be easily possible to mount the LED headlamp higher to provide better coverage of the innards.
- Pro tip: don't enter "innards" to google's image search.
For the final adjustments, add a windscreen for round headlights.

FX Dual to Single Battery
If you want to use your dual brick FX/FXS with a single battery, you need to place a special dummy plug in place of the missing battery to ride.
Apparently the FX/FXS are delivered with this plug zip-tied under the front of the seat.
