Rider Profile

Best ForThis bike suits newer to intermediate riders who want a light, approachable naked with modest power.
PurposeIt's built primarily for city commuting and casual street riding rather than outright speed or long-distance touring.
Rider FitThe low dry weight and moderate seat height make it manageable for riders of average or smaller stature.
CharacterIt has the simple, torquey, easygoing feel typical of a big-bore single-cylinder naked bike.
Not Ideal ForIt's not the right choice for riders seeking high-speed touring, pillion comfort, or serious off-road capability.

2006 Cagiva River 500 Rider Ergonomics Assessment

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

Feet:

At 810mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2006 Cagiva River 500, with a relaxed knee angle of around 120 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.
