How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- This is a classic all-rounder from the early 80s, built for confident street riding, weekend cruising, and light touring rather than outright performance or track use.
- Built for
- A smooth, torquey inline-four with classic UJM (Universal Japanese Motorcycle) charm, rewarding relaxed, steady-paced riding over aggressive cornering or high-speed antics.
- Not ideal for
- Not a good fit for off-road adventures, novice riders intimidated by weight, or anyone expecting modern sportbike agility or braking performance.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
