Rider Profile

Best ForThis is a youth/amateur competition machine best suited to developing riders with prior dirt bike experience moving up from smaller minis, not adult novices or road riders.
PurposeBuilt purely for motocross racing and track practice, not for trail riding, commuting, or general recreation.
Rider FitIts tiny 161 lb wet weight and low seat height suit smaller, lighter riders, typically pre-teens to young teens, rather than full-grown adults.
CharacterA high-strung, rev-happy two-stroke that rewards aggressive clutch and throttle work with sharp, flickable handling on motocross tracks.
Not Ideal ForNot for adult riders, highway use, long-distance touring, or anyone seeking a comfortable or forgiving first bike.

2014 Yamaha YZ85 Rider Ergonomics Assessment

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

Feet:

At 864mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2014 Yamaha YZ85, 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.
