How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built as a nimble supermoto-styled commuter for weaving through city traffic and having fun on twisty back roads rather than for outright speed.
- Built for
- Playful, flickable, and eager to be thrown around corners, it rewards an energetic riding style over long-distance cruising.
- Not ideal for
- It's not the right choice for riders wanting highway speed, long motorway touring comfort, or serious off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
