How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built for spirited street riding and weekend backroad carving where its high-revving four-cylinder character and light weight shine more than raw straight-line power.
- Built for
- It rewards riders who enjoy the mechanical sound and smoothness of a small-capacity inline-four spun to high RPM rather than short-shifting for low-end torque.
- Not ideal for
- This isn't the right bike for riders wanting effortless highway overtaking power or long-distance touring comfort with a passenger and luggage.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
