Rider Profile

Best ForThis machine suits riders with at least some prior experience on middleweight sport bikes rather than absolute beginners.
PurposeIt is built primarily as a sporty middleweight for spirited road riding and occasional track days rather than long-distance touring.
Rider FitA moderate 779mm seat height and 208kg dry weight demand reasonable rider fitness and confidence but remain manageable for most average-sized adults.
CharacterThe V2 engine layout paired with an inverted fork and adjustable monoshock suggests a torquey, characterful ride with sharp handling rather than outright top-end speed.
Not Ideal ForThis is not a good fit for riders seeking off-road capability, plush long-haul comfort, or a low-maintenance carbureted commuter.

2010 UM V2S-650R Rider Ergonomics Assessment

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

Feet:

At 779mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2010 UM V2S-650R, 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.
