=Overview=

This covers ergonomic characteristics of Zero models and what adjustments various people have made.

__TOC__

=Standover Height=
Standover height is the height of the seat when the bike is unloaded (but balanced upright).

There is a trend of models becoming shorter year by year from 2012-2014, after which the models' height stabilized through 2017.

==Reducing Seat Height==

;Issues
: Not enough third-party fitments are known for shocks or lowering links.

;Seat Solutions
: 2013 Zero FX and XU models offered an unlisted "[http://www.zeromotorcycles.com/zero-fx/2013/specs.php low seat accessory]" which reduced seat height by 2" (41mm).
: The [http://corbin.com/zero/zero13.shtml Corbin Gunfighter seat for Zero] is customizable and does provide easier leg reach to the ground in front, less than an inch by default.
: Carving out seat foam can be done with the stock seat to some extent (1 inch again?).
:: If you do this, check the underside of the seat for flexing.
:: High powered cables underneath should not be under load for any reason and this area needs to be reinforced by the "Y-bracket" or an equivalent that bolts across the frame sections there.

;Suspension Solutions
: See [[Aftermarket#Suspension|the aftermarket section on suspension]].
:;Front Fork
:: ([http://electricmotorcycleforum.com/boards/index.php?topic=4786.msg32176#msg32176 From a 2013 FX report]) The front fork can be slid up in the clamp by one inch.
:;Rear Shock
:: For the rear, have a local shock repair / re-build for racing shop put a 3/4" spacer inside the shock, to stop its extension length by 3/4".
:: Since it is about 2:1 lever ratio from the shock mount to the rear axle this would lower the rear of the bike by about 1 1/2".

==Raising Seat Height==
This is less commonly discussed.

=[[Seat]] to [[Footpegs|Footpeg]]=
* 2013+ Zero S Platform models all have the same (or nearly so) seat to footpeg distances.
* DS footpegs, because of their construction, actually offer ''less'' legroom than the S footpegs.
*: A swap can be accomplished easily.

[[File:footpeg-comparison.gif|400px|S and DS footpegs compared]]

=[[Handlebar]] Distance=
Shortening or changing the distance to the bars can be done by rotating the bars, adding risers, or installing a differently-shaped set of bars.
*: Bars are 7/8" at the grips, but that tapers from 1 1/8" or 28mm at the stem, e.g. Protapers brand tapered handlebars at CycleGear, which come in various angles.

=[[Handlebars|Handlebar]] Rise=
* S model bars typically have higher rise but are shorter and angled back.
* DS bars are wider, somewhat lower rise, and straighter.
*: 2013-2014 shape differs from 2015+ shape.

==Seat Angle==
The Zero stock seat is relatively flat/neutral, perhaps a few degrees angled forward.

=Cockpit=
The Zero cockpit is relatively short among motorcycle forms.

==[[Instrument Cluster|Instrument Cluster]]==
The instrument cluster is not typically visible when looking at the horizon from an upright position.

* Riding in a crouched position makes viewing the instrument cluster easier for some, but strains the neck and shoulders.
* The handlebars are at the same height, which means that a phone mount typically will not rise much higher than that into the rider's field of view.
* On 2012-2013 models, the Koso instrument cluster makes ignition access more difficult.
