Rider Profile

Best ForBest suited to riders with at least some experience on tall, lightweight single-cylinder bikes, though a confident beginner could adapt quickly.
PurposeBuilt primarily for off-road and light dual-sport riding, with enough manners to serve as a simple commuter or backroads scratcher.
Rider FitThe tall 880mm seat height and lean 167kg dry weight favor taller or more agile riders comfortable balancing a narrow, top-heavy machine at low speeds.
CharacterA no-frills, torquey thumper that rewards a relaxed, back-to-basics riding style over outright speed or refinement.
Not Ideal ForNot a good fit for riders wanting sustained highway comfort, passenger-friendly touring, or strong outright acceleration.
