Rider Profile

Best ForThis bike suits beginners and new riders learning clutch control, low-speed handling, and basic road skills.
PurposeIt was designed as an approachable, low-intimidation machine for learning to ride and for light urban commuting rather than performance riding.
Rider FitIts low seat height and light dry weight make it easy for shorter or less experienced riders to manage at a stop and while maneuvering.
CharacterThe single-cylinder air-cooled engine gives it a simple, forgiving, low-revving character with modest torque delivered low in the rev range.
Not Ideal ForIt is not suited to riders wanting highway touring comfort, high-speed performance, passenger carrying, or off-road capability.

2004 Buell Blast Rider Ergonomics Assessment

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

Feet:

At 775mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2004 Buell Blast, 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.
