This covers ergonomic characteristics of Zero models and what adjustments various people have made.
- A good reference which has some Zero modeling is Cycle Ergo.
- How and Why We Measure Motorcycle Ergonomics
Standover height is the height of the seat when the bike is unloaded (but balanced upright).
Reducing Seat Height
- Not enough third-party fitments are known for shocks or lowering links.
- Known Solutions
- The 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?).
- (From a 2013 FX report) The front fork can be slid up in the clamp by one inch. 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".
- Hollywood Electrics shows signs that they might offer a suspension upgrade kit for older (2013-2014) models. They're certainly able to answer customization questions.
Raising Seat Height
This is less commonly discussed.
Seat to Footpeg
2013+ Zero S Platform models all have the same (or nearly so) seat to footpeg distances.
Seat to Bars
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.
The Zero stock seat is relatively flat/neutral, perhaps a few degrees angled forward.
