Rider Profile

Best ForBest suited to intermediate-to-experienced riders comfortable with a light, torquey single that demands active input and rewards confidence.
PurposeBuilt for aggressive cornering, supermoto-style track days, and sharp, playful street riding rather than covering long distances.
Rider FitThe tall seat height and minimal wind protection favor taller riders with good balance and leg strength for standing and flicking the bike around.
CharacterA raw, high-strung big-bore single that feels like a dirt bike with street tires, delivering thrilling agility and punchy low-end torque.
Not Ideal ForNot a good fit for riders wanting plush comfort, pillion-friendly touring capability, or a mellow, low-maintenance commuter.
