Rider Profile

Best ForIdeal for beginners and newly licensed riders; approachable power and light weight also make it a fun, easy commuter for experienced riders.
PurposeUrban commuting and spirited backroad riding on a budget-friendly naked twin; a nimble, everyday A2-friendly street bike.
Rider FitLow 30.7in seat and slim 373lb chassis make it easy to manage; upright naked ergonomics with a fairly relaxed reach.
CharacterFriendly, playful and forgiving; the 321cc twin is smooth and eager without being intimidating, rewarding rider confidence.
Not Ideal ForNot for highway tourers, two-up long-haul trips, or riders chasing big-bore horsepower and outright top speed.
