How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- A small-displacement full-fairing sportbike built for spirited canyon runs, twisty backroads, city commuting and occasional track days.
- Built for
- Nimble, revvy and confidence-inspiring. The 321cc twin loves to be wound out, rewarding smooth inputs while staying gentle enough not to intimidate.
- Not ideal for
- Not for riders chasing big highway power, long two-up touring comfort, or any off-road use. Taller/heavier riders may find it cramped over distance.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
