How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- A lightweight, minimalist retro roadster meant for relaxed street riding, short jaunts, and enjoying the mechanical simplicity of a big-bore single rather than outright performance.
- Built for
- Charming, characterful, and old-school, this bike delivers a raw, thumping single-cylinder feel with modest performance but big personality and simplicity.
- Not ideal for
- Not suited for riders seeking high-speed touring, long highway distances, passenger comfort, or any serious off-road capability.
