Rider Profile

Best ForThis big single-cylinder naked suits riders with at least some experience handling a torquey, thumper-style engine and a tall seat height.
PurposeBuilt primarily as an urban and backroad naked bike, favoring nimble handling over outright speed or long-distance comfort.
Rider FitThe 810mm seat height and lean 165kg dry weight demand reasonable leg length but make the bike easy to muscle around at low speeds.
CharacterIt has a raw, single-cylinder character with punchy low-end torque, a light chassis, and sharp, motard-influenced handling.
Not Ideal ForThis is not the right bike for riders seeking sustained highway speed, long-haul touring comfort, or serious off-road capability.

2011 Derbi Mulhacen 659 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 2011 Derbi Mulhacen 659, 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.
