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.
