How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built primarily for sharp, playful cornering and mini-GP style track days or learner sport riding rather than outright speed.
- Built for
- It behaves like a nimble, high-revving pocket racer that loves flicking through tight corners but runs out of breath on long straights or highways.
- Not ideal for
- This bike is not for riders seeking high-speed touring, passenger comfort, or off-road capability.
