Rider Profile

Best ForBest suited to riders with at least some off-road or dual-sport experience, given the tall seat height and dirt-oriented ergonomics.
PurposeDesigned primarily for trail riding and dual-sport exploration rather than outright speed or highway cruising.
Rider FitThe tall 35.8 inch seat height and narrow perimeter-frame stance favor taller or more confident riders who can comfortably handle the bike standing or at a stop.
CharacterA light, single-cylinder trail bike with a lively, torquey feel and nimble handling suited to technical terrain and tight trails.
Not Ideal ForNot a good fit for riders wanting sustained high-speed highway touring or two-up comfort over long distances.
