How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's a classic sport-touring middleweight best suited to spirited backroad rides and moderate-distance trips rather than outright speed or long-haul touring comfort.
- Built for
- Smooth, revvy inline-four charm with a classic 1980s Japanese UJM feel, rewarding riders who enjoy mechanical simplicity and analog engagement over modern refinement.
- Not ideal for
- It's not the right choice for riders seeking off-road capability, high-speed touring comfort, or modern braking and suspension performance.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
