Rider Profile

Best ForThis is a small-wheeled 50cc pit-bike-style machine best suited to young riders or beginners learning basic motocross skills in a low-stakes setting.
PurposeDesigned as a mini cross/motocross trainer for kids or lightweight adults practicing on dirt tracks and backyard courses, not for serious racing or transportation.
Rider FitIts tiny 660mm seat height and compact frame make it accessible to small or young riders, but adults will find it cramped and underpowered.
CharacterA playful, budget-friendly mini-moto with real suspension travel and disc brake feel, giving a taste of motocross ergonomics at a fraction of the size and speed.
Not Ideal ForIt is not suitable for adult-sized riders, highway use, long-distance touring, or anyone expecting real off-road performance or power.

2006 PRC (Pro Racing Cycles) PRC (pro Racing Cycles) Phantom LX 50 Rider Ergonomics Assessment

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

Feet:

At 660mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2006 PRC (Pro Racing Cycles) PRC (pro Racing Cycles) Phantom LX 50, with a cramped knee angle of around 55 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.
