How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Best suited to spirited street riding and short scenic runs where classic styling and a revvy four-cylinder engine matter more than outright pace.
- Built for
- This is a nimble, characterful retro-styled machine that rewards smooth throttle input and enjoys being ridden at a lively pace rather than in a straight line.
- Not ideal for
- It is not the right choice for riders seeking modern touring comfort, high-speed highway cruising, or any form of off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
