Rider Profile

Best ForThis is a youth/amateur-level 84cc motocross machine best suited to smaller or younger riders building race experience, not seasoned adult veterans.
PurposeBuilt purely for closed-course motocross racing and dirt track practice, not for any form of street or commuter use.
Rider FitIts light 70kg weight and compact 870mm seat height make it manageable for smaller-statured or younger riders, though the tall suspension travel demands active standing riding.
CharacterA high-strung two-stroke racer that rewards aggressive riding, quick throttle inputs, and precise line choice on jumps and berms.
Not Ideal ForNot suitable for taller adults, highway travel, daily commuting, or anyone seeking comfort, passenger capacity, or long-distance touring.

2007 Kawasaki KX85 II Rider Ergonomics Assessment

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

Feet:

At 870mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2007 Kawasaki KX85 II, with a cramped knee angle of around 75 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.
