How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a big-bore UJM muscle-tourer, it excels at effortless high-speed cruising and long-distance shaft-drive reliability rather than sharp handling.
- Built for
- It has the soul of an early-80s superbike brute: torquey, stable in a straight line, and imposing rather than nimble.
- Not ideal for
- It's not for new riders or anyone wanting a light, flickable machine for tight twisty roads or off-road trails.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
