How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's designed for nimble city commuting and playful short rides rather than sustained high speed or distance.
- Built for
- Expect a peppy, upright, flickable little bike with sharp steering geometry typical of the supermoto style, but limited top-end punch from its 125cc single.
- Not ideal for
- It's not a good fit for riders wanting highway touring, pillion comfort, or genuine off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
