How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built for mimicking full-size supersport looks and sharpening cornering skills at low speed and low risk rather than for outright performance.
- Built for
- It has the sharp, aggressive persona of a miniature race replica, eager to be revved hard and flicked through corners.
- Not ideal for
- It is not suited to riders wanting real highway speed, long-distance touring comfort, or two-up passenger practicality.
