How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- A lightweight sport bike for spirited canyon rides, commuting, and entry-level track days rather than long-distance touring.
- Built for
- Nimble, approachable, and revvy parallel-twin sportbike that punches above its 399cc for grins without intimidating newer riders.
- Not ideal for
- Not for riders wanting big-bore highway punch, two-up touring range (tiny 3.7L tank), or any off-road use.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
