Rider Profile

Best ForThis is a youth-focused motocross machine intended for young, developing riders progressing beyond a smaller minicycle, not for adult or beginner street riders.
PurposeBuilt purely for motocross track use, it exists to teach race craft and jumping/cornering skills on a scaled-down competition bike.
Rider FitIts tiny 73 kg mass, low-ish 850 mm seat height, and compact dimensions are tailored to lightweight junior riders rather than full-size adults.
CharacterThe two-stroke reed-valve engine and fully adjustable suspension give it a peppy, eager, revvy character typical of small-bore motocross bikes, rewarding an active, aggressive riding style.
Not Ideal ForIt is not suitable for adult riders, road use, touring, commuting, or carrying a passenger.

2021 Suzuki RM85 Rider Ergonomics Assessment

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

Feet:

At 850mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2021 Suzuki RM85, 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.
