Gen2/Swingarm

The swingarm is a dual-sided structure made in the same way as the frame. It's very sturdily constructed for its light weight.

Swingarm

The front pivots on the axis of the motor to minimize belt strain with suspension travel.

It has fitments for the rear axle including belt tension adjustment.

Mounting

The swingarm joins the frame at left and right pivot points.

The each side pivot has a stack of (from outside inward):

• A rubber cover
• A bolt with a 10mm hex drive.
• The bearing (6204; 6204RS for 2015+ models)

Swingarm Tube

There is a hollow tube through the swingarm across the arms forming a join point for the rear shock to the frame tube on the SDS platform.

Swingarm Tube with measurements

Its shape is flattened on the rear side, presumably to clear the largest-diameter potential tire.

It makes a reasonable storage tube if some padding or caps are used to secure the cargo there (like a charging cord).

Measurements

Inner diameter	75mm	2.91"
Horizontal width to flat side	68mm	2.68"
Swingarm greatest width below tube	295mm	11.61"

Swingarm Bearings

The swingarm bearings are generally the same as the wheel bearings (6204; 6204RS for 2015+ models).

Swingarm Removal

Tools

• Center lift or other lift that gets the rear wheel off the ground without contacting the swingarm.
• 27mm socket or spanner.
• 3mm Allen key.
• 10mm Allen key socket

  Ensure at least 1" depth and a ⅜" drive sufficient to handle swingarm pivot bolt torques.

• 15mm socket wrench (S models).
• 13mm socket wrench (X models).
• Torque wrench capable of setting 75ft-lbs and driving the 27mm socket and 10mm Allen key.
• 2012-2013:
  • 2.5mm Allen key.
  • 24mm socket wrench.

Steps

NOTE: For roadside removal, particularly for an FX or FXS, setting the bike on its side should be possible for this work.

However, no effective procedure has been described for the process.

The following steps are suited to garage locations.

Bike on center lift

1. Use a lift to raise the bike from the center.

   A sturdy wood crate may work in a pinch. Be safe.

   If the lift can be adjusted, lift the rear wheel just off the ground for ease of removal and replacement (lower than depicted but not in contact).

2. Pull the wheel off (or slide it forward) by loosening the axle nut with a 27mm wrench.
3. Pull off the rear tire fender by taking out the 4 hex bolts securing it with a 3mm Allen wrench.

   You can get away with removing only the left-side screws, to allow lifting the fender up enough to get the belt under.

   The right side fasteners also anchor the brake line to the rear calipers and a grounding strap, so mind them for re-attaching in the same way.

4. Remove the brake pedal:

   This creates clearance for loosening the swingarm bolt above it (might be optional for pre-2015 models).

5. Get the rear brake pedal out of the way of the right side swingarm pivot bolt.

   SDS platform: Use the 15mm hex socket to loosen or remove the bolt forming the pedal pivot.

   XMX platform:

   1. Remove the pin that attaches the brake pedal to the piston.
   2. Remove the two 13mm bolts that hold the grey piston bracket to the frame, and gently move the whole assembly to the left.

6. XMX platform: To access the left swingarm bolt, remove the lower left passenger peg bolt (13mm) and remove the grey cover piece.
7. Remove the left and right swingarm bolts.

   2012-2013

   Remove the set screws from the swingarm bolts on both sides with a 2.5mm Allen wrench.

   The set screw is very difficult to find.

   It is located in one of the sides of the 24mm hex nut, perpendicular to the long axis of the 10mm allen bolts.

   It is actually on the edge of the nut.

   The best way to locate it is to use a small mirror and a strong flashlight.

   Then remove the bolts by holding the inside nut with a 24mm wrench, and a 10mm hex on the head.

   This was the hardest step, because there is not a lot of room to manipulate in the rear assembly - especially with a 24mm wrench!

   2014+

   Remove the left and right swing arm bolts with a 10mm Allen wrench.

   

   Swingarm Bolt

8. Hang the swing arm with a strap on the tail section.

   The swingarm will pull back enough for the belt to fit through the frame.

   

   Pulling the Swingarm

   

   Swingarm Pulled

9. Remove the belt.
10. Disconnect the rear shock from the swingarm, then gently pull the swingarm from its suspended arrangement. Take car that the small spacers do not fall out and roll away, one on each side.
