Rider Profile

Best ForThis bike suits riders with at least some prior experience, since its light weight and punchy single-cylinder torque reward confident, active riding.
PurposeIt's built as a characterful, lightweight naked bike for spirited urban riding and twisty backroads rather than long-distance travel or outright top speed.
Rider FitThe low-ish seat height range and very light dry weight make it easy to manage at a stop and in low-speed maneuvering, though the tall single-cylinder engine and firm suspension travel mean it still feels compact but purposeful underneath you.
CharacterExpect a raw, torquey, mechanical feel typical of a big-bore single with twin-spark injection, giving strong low-end pull and an engaging, slightly vibratory personality rather than smooth multi-cylinder refinement.
Not Ideal ForIt's not the right choice for riders wanting sustained high-speed touring, a plush passenger experience, or any serious off-road capability.

2009 CR&S Cr&s VUN Fifties Rider Ergonomics Assessment

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

Feet:

At 780mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2009 CR&S Cr&s VUN Fifties, with a moderate knee angle of around 115 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.
