Rider Profile

Best ForThis is a small-wheel 85cc motocross machine built for younger or smaller-statured riders who are progressing from mini bikes toward full-size motocross machines.
PurposeIt exists purely for competitive motocross racing on dirt tracks, not for street use, commuting, or leisure riding.
Rider FitIts low dry weight and compact 823mm seat height make it manageable for lighter or younger riders, though the demands of motocross still require good fitness and bike control.
CharacterIt is a high-strung, race-focused two-stroke that rewards aggressive riding, high revs, and precise technique with sharp, flickable handling.
Not Ideal ForIt is not suitable for taller or heavier adult riders, road use, touring, commuting, or carrying a passenger.

2006 Honda CR 85 R Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 823mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2006 Honda CR 85 R, with a cramped knee angle of around 70 degrees and an upright riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
