Rider Profile

Best ForThis big-bore single rewards experienced off-road riders who can manage its punchy low-end torque and tall, top-heavy stance at low speeds.
PurposeBuilt as a serious enduro machine, it excels at trail riding, technical terrain, and competitive off-road use rather than commuting or highway cruising.
Rider FitAt a light 134 kg but with a tall seat height typical of early-90s enduros, riders need good fitness, leg length, and core strength to control it standing on rough terrain.
CharacterIt has the raw, torquey, slightly unpredictable character of a big-bore liquid-cooled single, feeling agile and eager rather than smooth or refined.
Not Ideal ForIt is not a good fit for new riders, passenger touring, or anyone wanting plush comfort and stability on long paved journeys.
