Rider Profile

Best ForThis bike suits riders with at least intermediate experience who are comfortable managing a heavy, powerful early-90s sport tourer.
PurposeBuilt as a sport tourer, it blends solid straight-line performance with a more relaxed, mile-covering riding position than a pure sportbike.
Rider FitAt 261 kg, it demands a rider of reasonable strength and confidence, especially at low speeds or when maneuvering it off the kickstand.
CharacterIt offers a torquey, muscular in-line four character with enough top-end power to feel genuinely quick for its era, without the razor-edge aggression of a full race replica.
Not Ideal ForIt is not well suited to lightweight-seeking beginners, off-road use, or riders prioritizing nimble city commuting.
