Rider Profile

Best ForThis small-displacement V-twin sportbike suits newer riders or those wanting a manageable step into sport-styled machines, though the lack of published horsepower figures means some scores here are estimated from its class and layout.
PurposeIt is built primarily for spirited street riding and short sporty jaunts rather than outright speed or long-distance travel.
Rider FitA relatively low seat height and modest dry weight make it accessible to shorter or less experienced riders without excessive physical demands.
CharacterThe air-cooled V2 engine and inverted forks give it a distinctive, characterful feel that trades outright performance for personality and rider engagement.
Not Ideal ForIt is not the right choice for riders seeking highway touring comfort, passenger-friendly ergonomics, or off-road capability.

2010 UM V2S-250R Rider Ergonomics Assessment

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

Feet:

At 795mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2010 UM V2S-250R, with a cramped knee angle of around 70 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.
