Rider Profile

Best For	This is a lightweight learner-friendly two-stroke best suited to beginners or younger riders cutting their teeth on a small-bore sportbike.
Purpose	It's a nimble, playful mini sportbike built for buzzing around town and back roads rather than covering serious distance or carrying real speed.
Rider Fit	Its very low dry weight and low seat height make it easy to manage for smaller or less experienced riders.
Character	Expect a rev-happy, high-pitched two-stroke character that rewards keeping the engine spinning hard through its six-speed gearbox to extract any real performance.
Not Ideal For	It's not the right choice for anyone wanting genuine highway speed, long-distance touring comfort, or the ability to carry a passenger with ease.

Units

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

Feet:

At 765mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 1982 Yamaha RD 80 LC, with a cramped knee angle of around 65 degrees and a forward-leaning riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
