How it rides
Editorial estimate from the spec sheet - not lab tested- Best for

- Built for
- It has a smooth, classic air-cooled inline-four character with linear power delivery and shaft-drive reliability rather than aggressive urgency.
- Not ideal for
- This is not the bike for riders seeking modern sportbike acceleration, aggressive cornering clearance, or any off-road capability.
