At 955mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with cannot reach comfortably on the 2011 Suzuki RM-Z450, 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.
