Rider Profile

Best ForBest suited to intermediate-to-experienced riders who are comfortable with a tall, light, powerful single-cylinder machine that demands active input.
PurposeBuilt primarily as a big-bore enduro weapon for serious off-road riding, trail exploration, and technical terrain, with light road use as a secondary role.
Rider FitThe tall 935mm seat height and 152kg dry-oriented weight favor taller or more athletic riders who can confidently manage standing, shifting body weight, and paddling the bike at low speed.
CharacterA raw, torquey big single with a lightweight chassis rewards decisive, engaged riding and punishes hesitation, giving it a focused, no-nonsense personality.
Not Ideal ForNot a good fit for riders wanting plush comfort, pillion-friendly touring, or a low-effort commuter experience.
