Rider Profile

Best ForThis naked V-twin suits riders with some prior experience who want a mid-weight machine with real-world torque rather than outright top-end speed.
PurposeBuilt as a sporty naked streetfighter, it's meant for spirited road riding, commuting with character, and weekend backroad fun rather than long-distance touring or racing.
Rider FitAt 200 kg with a 780 mm seat height, it's a manageable but not featherweight bike, favoring riders of average to taller stature with reasonable strength for low-speed maneuvers.
CharacterThe V2 engine and short exhaust give it a distinctive, torquey, slightly rough-and-ready personality that rewards riders who enjoy mechanical charisma over refined smoothness.
Not Ideal ForIt's not a good fit for off-road riders, those seeking cutting-edge performance, or riders wanting a comfortable long-haul touring platform with wind protection and luggage capacity.
