Rider Profile

Best For	Best suited to riders with at least some prior motorcycle experience who can manage a moderately heavy, air-cooled four-cylinder machine with dated brakes and suspension by modern standards.
Purpose	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.
Rider Fit	At 256 kg with a tall-ish stance and no modern rider aids, it demands reasonable strength and confidence at low speed, parking, and in stop-and-go traffic.
Character	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.
