How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Designed as a sharp-handling supermoto for flicking through city traffic and tight, twisty backroads rather than covering long distances or high speeds.
- Built for
- A nimble, high-revving single-cylinder machine that rewards an eager, playful riding style over outright power or long-distance comfort.
- Not ideal for
- Not a good fit for riders wanting sustained high-speed cruising, long motorway touring, 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.
