How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a boutique power-naked, it exists to deliver explosive straight-line performance and razor-sharp handling rather than practicality.
- Built for
- It has the soul of a hand-built, exotic muscle bike, aggressive, mechanical, and unapologetically focused on visceral thrills.
- Not ideal for
- This is not the bike for new riders, commuters seeking comfort, or anyone wanting a relaxed touring or off-road companion.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
