How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- This bike suits riders who want a classic, versatile naked machine for commuting, weekend rides, and light touring rather than outright performance.
- Built for
- The air-cooled inline-four and shaft drive give it a smooth, mechanical charm with steady, unhurried power delivery rather than aggressive thrills.
- Not ideal for
- It's not the right choice for riders seeking modern sportbike agility, off-road capability, or class-leading acceleration.
