Rider Profile

Best For	Best suited to riders with at least intermediate off-road experience, since the tall seat height and torquey single-cylinder power delivery reward confident clutch and body control.
Purpose	Built as a big-bore dual-sport adventure machine, it excels at long gravel and trail routes with the ability to cover real distance thanks to its large fuel tank.
Rider Fit	The 935mm seat height and 154kg dry weight demand decent rider height and strength, especially when navigating technical off-road terrain or picking the bike up after a drop.
Character	A gruff, characterful big single that rewards a relaxed, standing-up riding style with strong low-end torque and a rugged, go-anywhere feel.
Not Ideal For	Not a good match for shorter riders, pure pavement commuters seeking smoothness, or anyone wanting sport-bike acceleration and top-end speed.
