Rider Profile

Best For	Best suited to intermediate or experienced riders comfortable with a light, quick-steering, top-heavy-feeling single that rewards precise inputs.
Purpose	Built as a supermoto for sharp cornering, flickable street-track riding, and attacking twisty tarmac rather than covering long distances or rough terrain.
Rider Fit	The tall 860mm seat height and lightweight 119kg dry chassis favor taller or more agile riders who can manage a firm, aggressive riding position.
Character	A punchy, high-strung single-cylinder supermoto with razor-sharp handling, minimal weight, and a raw, focused riding experience.
Not Ideal For	Not a good fit for riders seeking plush comfort, passenger-friendly ergonomics, long-distance touring capability, or serious off-road ground clearance and suspension travel.

Units

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

Feet:

At 860mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2009 GAS GAS SM450 Halley, with a relaxed knee angle of around 135 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.
