How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- A lightweight middleweight naked built for commuting, city hopping and spirited weekend backroad rides, with enough legs for occasional short highway trips.
- Built for
- Nimble, playful and easygoing. The parallel-twin revs eagerly, brakes and ABS inspire confidence, and the flickable trellis-framed chassis rewards without overwhelming.
- Not ideal for
- Not for riders craving big-bore highway punch, long two-up touring, or any off-road use. Tall riders and those wanting relaxed cruising may find it small and buzzy.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
