How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- A pure sport machine designed for spirited backroad riding and track days rather than practical transportation.
- Built for
- A revvy, high-strung 400cc four-cylinder that rewards riders who like to keep the engine spinning near its top end to unlock its performance.
- Not ideal for
- Not a good fit for riders seeking long-distance comfort, passenger-friendly ergonomics, or low-speed practicality in daily commuting.
