Rider Profile

Best For	Best suited to riders with some experience handling a heavier, shaft-driven machine with classic-era brakes and suspension.
Purpose	A classic Japanese custom/cruiser built for relaxed shaft-driven cruising and boulevard riding rather than outright performance.
Rider Fit	At 258 kg the bike demands a confident, physically capable rider, especially at low speeds and when maneuvering or parking.
Character	The smooth in-line triple and shaft drive give it a refined, torquey character with a distinctive exhaust note typical of early 80s Yamaha triples.
Not Ideal For	Not a good fit for riders seeking sharp cornering agility, off-road capability, or modern sportbike-level acceleration.
