How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- This bike is built for spirited backroad riding and trackday-style cornering fun rather than outright top-speed bragging rights.
- Built for
- A high-revving inline-four screamer that rewards riders who like to work the gearbox and chase the redline for its performance.
- Not ideal for
- Not a good match for riders wanting relaxed all-day touring comfort, heavy luggage capacity, or off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
