Rider Profile

Best ForThis is best suited to new or young riders, often learner-legal, who are building basic skills and confidence on a lightweight sportbike-styled machine.
PurposeDesigned as a small-displacement sport mini-bike for learning corner craft, commuting short distances, and having fun rather than for outright speed.
Rider FitIts light dry weight and low seat height make it very easy to manage and flick around for smaller or less experienced riders.
CharacterIt has a sharp, toy-like sportbike character with race-inspired cycle parts that reward a playful, revved-out riding style typical of small two-strokes.
Not Ideal ForIt is not suitable for riders seeking real highway speed, long-distance touring comfort, off-road capability, or carrying a passenger.

2008 Rieju RS2 Pro 50 Rider Ergonomics Assessment

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

Feet:

At 800mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2008 Rieju RS2 Pro 50, with a cramped knee angle of around 70 degrees and a forward-leaning 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.
