How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Designed for flicking through city traffic and having playful fun on tight, twisty backroads rather than covering long distances or carrying speed on the highway.
- Built for
- A cheeky, flickable little street bike with supermoto styling and stance, offering sharp handling and a fun personality rather than outright performance.
- Not ideal for
- Not a good choice for riders wanting sustained motorway speeds, long-distance touring comfort, or serious off-road capability.
