Rider Profile

Best ForThis is an entry-level machine built specifically for very young or first-time riders, not for anyone with prior road or trail experience seeking performance.
PurposeIt exists purely to teach small children the basics of throttle control and balance on light, low-speed off-road terrain.
Rider FitThe extremely low seat height and featherweight chassis make it accessible to small kids, but adults or teens will find it comically undersized.
CharacterIt is a gentle, forgiving, automatic-clutch minibike designed to build confidence rather than deliver thrills.
Not Ideal ForThis is not for teenagers or adults, highway use, touring, or anyone wanting real speed or off-road capability.

2018 Yamaha TT-R50E Rider Ergonomics Assessment

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

Feet:

At 556mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2018 Yamaha TT-R50E, with a cramped knee angle of around 45 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.
