How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for sharp, flickable cornering fun on twisty tarmac and supermoto-style thrills rather than covering long distances.
- Built for
- A raw, mechanical, big-single supermoto that rewards aggressive, engaged riding with immediate steering response and strong midrange torque.
- Not ideal for
- Not a good fit for riders wanting plush comfort, pillion practicality, or effortless long-haul touring capability.
