Rider Profile

Best For	This is a small-wheeled 65cc motocross machine built specifically for young or lightweight developing riders, not adults or novices to the sport.
Purpose	It exists purely for competitive motocross training and racing at the youth level, with race-grade suspension and chassis components scaled down to size.
Rider Fit	The low 819 mm seat height and 52.6 kg dry weight suit a small, light rider, likely a child or young teenager progressing through junior motocross ranks.
Character	Despite its tiny engine, the fully adjustable inverted forks and Penske shock give it genuine race-bike behavior, rewarding smooth technique and aggressive cornering over raw power.
Not Ideal For	It is not suitable for adult riders, road use, touring, or anyone seeking a powerful or comfortable ride, as it is a pure small-displacement off-road racing tool.

Feet:

At 819mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2008 PRC (Pro Racing Cycles) PRC (pro Racing Cycles) RR-65, with a cramped knee angle of around 70 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.
