How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as an early-80s sport-touring flagship, it favors strong straight-line speed and long-distance capability over nimble cornering.
- Built for
- It has the classic heavyweight UJM character: a punchy air-cooled inline-four with a top speed near 228 km/h, wrapped in a chassis that rewards smooth, deliberate riding rather than flickable agility.
- Not ideal for
- It is not a good fit for new riders seeking a light, agile bike or for anyone planning genuine off-road use.
