How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a modern homage to 1980s superbikes, it excels at strong midrange pulls, naked-bike street riding, and occasional spirited backroad or track-day use rather than pure racing.
- Built for
- It has a raw, muscular, and nostalgic personality, favoring brute torque and stability over cutting-edge lightness or agility.
- Not ideal for
- It is not a good fit for off-road use, absolute beginners, or riders seeking a lightweight, ultra-nimble modern sportbike.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
