Rider Profile

Best ForThis is a bike best suited to experienced riders who are comfortable with a light, torquey, quick-turning machine that offers little forgiveness for mistakes.
PurposeBuilt primarily for supermoto-style sharp cornering and dirt-track-derived agility rather than straight-line speed or long-distance travel.
Rider FitIts tall seat height, minimal weight, and bare-bones ergonomics demand an active, fit rider comfortable standing and shifting body weight aggressively.
CharacterA raw, lightweight single-cylinder motard with race-bred Ohlins suspension, rewarding precise, aggressive riding over relaxed cruising.
Not Ideal ForThis is not the right bike for riders seeking plush comfort, pillion capability, or a relaxed touring experience.

2008 ATK 450 Dirt Track Rider Ergonomics Assessment

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

Feet:

At 762mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2008 ATK 450 Dirt Track, with a relaxed knee angle of around 120 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.
