Rider Profile

Best ForSuits riders with at least some prior experience, as the low seat and cruiser stance are approachable but the bike's weight and V-twin torque reward a confident hand.
PurposeBuilt primarily as a stylish custom cruiser for relaxed boulevard riding rather than outright speed or performance.
Rider FitThe low 698mm seat height and relaxed cruiser ergonomics make it accessible to shorter riders, though the near-226kg dry weight demands some strength at low speeds and when maneuvering.
CharacterA laid-back, torque-driven V-twin cruiser with classic custom styling, a belt final drive for smooth power delivery, and modest liquid-cooled DOHC performance rather than aggressive sportiness.
Not Ideal ForNot the right choice for riders seeking track performance, off-road capability, or sharp, agile handling in tight corners.

2007 UM V2C-650S Rider Ergonomics Assessment

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

Feet:

At 706mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2007 UM V2C-650S, with a cramped knee angle of around 75 degrees and an upright riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
