How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a supermoto, it excels at flickable, aggressive cornering on tight tarmac roads and track days rather than covering long distances.
- Built for
- It rewards a playful, aggressive riding style with sharp throttle response, strong brakes, and razor-quick handling at the expense of outright comfort.
- Not ideal for
- This is not the right choice for riders seeking a plush, stable long-distance tourer or a relaxed, low-maintenance daily commuter.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
