How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for spirited backroad carving and weekend sport-naked riding rather than commuting or long-distance touring.
- Built for
- A raw, characterful Italian street brawler with a growly Testastretta-derived V2 engine, strong midrange torque, and taut sport-oriented chassis manners.
- Not ideal for
- Not a good fit for beginners seeking a forgiving first bike or for riders wanting long-haul comfort, wind protection, or off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
