Rider Profile

Best For	This bike suits an early-intermediate rider comfortable with a classic air-cooled inline-four that rewards revving rather than raw torque.
Purpose	It's built as a versatile 1980s standard naked, equally at home commuting, weekend backroad riding, or light sport use.
Rider Fit	A moderate seat height and manageable curb weight around 198 kg make it accessible to riders of average build and experience.
Character	The Radian delivers classic Japanese four-cylinder charm with smooth power delivery, a free-revving nature, and simple, honest handling.
Not Ideal For	It's not the right choice for riders wanting off-road capability, modern touring comfort, or serious high-speed sport performance.

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 1986 Yamaha YX 600 Radian, with a moderate knee angle of around 115 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.
