Rider Profile

Best ForThis lightweight two-stroke enduro suits beginner to intermediate riders who want a nimble, forgiving bike to learn offroad skills on.
PurposeBest suited to trail riding, light offroad exploration, and playful low-speed technical terrain rather than any kind of speed or distance work.
Rider FitIts low dry weight and tall but narrow seat make it easy to manage standing up or paddling through rough ground, though the 850mm seat height demands reasonable inseam length.
CharacterA buzzy, high-revving two-stroke single that rewards active riding, frequent gear changes, and a willingness to keep the engine spinning for any real performance.
Not Ideal ForNot for riders wanting highway comfort, passenger capability, or sustained high-speed touring.

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

Feet:

At 860mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with tip-toe one foot on the 1999 Sachs ZX 125, with a cramped knee angle of around 75 degrees and a slightly forward riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
