Rider Profile

Best For	This is an entry-level 50cc two-stroke best suited to beginners, learners, or younger riders taking their first steps on a motorcycle.
Purpose	Designed as a lightweight sport-styled moped for short urban hops and learning basic riding skills rather than any serious performance riding.
Rider Fit	Its tiny 80kg dry weight and compact dimensions make it extremely easy to handle and manageable for riders of almost any size or strength.
Character	A sporty-looking but low-powered two-stroke single that rewards revving and light, nimble handling over outright speed.
Not Ideal For	This is not for experienced riders seeking real performance, highway travel, long-distance touring, or carrying a passenger comfortably.

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

Feet:

At 745mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2003 Yamaha RZ 50, with a moderate knee angle of around 105 degrees and a slightly forward 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.
