How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's designed as a light, nimble all-rounder for spirited city riding and twisty backroads rather than outright speed or long-distance cruising.
- Built for
- It has the personality of a peppy, high-revving inline-four that rewards spinning it up through the gears for its performance rather than relying on low-end torque.
- Not ideal for
- It's not a good fit for riders wanting serious highway touring comfort, passenger-friendly ergonomics, or any off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
