PurposeBuilt as a competition-focused enduro bike for trails, cross-country racing, and technical off-road terrain rather than road use.
Rider FitThe tall 950mm seat height and minimal seat padding demand a taller rider with good fitness and standing-based riding technique.

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

Feet:

At 955mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2014 Suzuki RMX450Z, 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.
