Rider Profile

Best ForThis is a pure competition motocross bike best suited to experienced or intermediate off-road riders comfortable with a peaky two-stroke powerband.
PurposeBuilt exclusively for motocross track riding and racing, not for street or general recreational use.
Rider FitIts tall 950mm seat height, lightweight 87kg chassis, and aggressive ergonomics demand good rider fitness, strength, and off-road skill to manage standing and cornering loads.
CharacterA raw, high-revving two-stroke racer that rewards aggressive riding, precise clutch and throttle control, and active body positioning on the track.
Not Ideal ForThis is not suitable for commuting, touring, passengers, or casual road riders since it is unregistered, uncomfortable at low speed, and lacks lights or road equipment.

Feet:

At 965mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2002 Suzuki RM 125, with a cramped knee angle of around 85 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.
