How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- This is a big-bore air-cooled sport-tourer built for sustained highway cruising and covering long distances with power in reserve rather than for tight, technical riding.
- Built for
- A classic UJM (Universal Japanese Motorcycle) heavyweight with strong, linear four-cylinder power delivery, shaft-drive smoothness, and a relaxed, stable highway character.
- Not ideal for
- Not for riders seeking a light, flickable bike for city commuting or aggressive cornering, nor for any kind of off-road use.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
