Rider Profile

Best ForSuits riders who appreciate classic motorcycling and are comfortable with the quirks and lighter electronics of an early-1980s British parallel twin.
PurposeBuilt as a traditional air-cooled roadster for spirited weekend rides and short trips rather than serious distance touring or track work.
Rider FitA modest 206 kg curb weight and low-to-moderate seat height make it manageable for riders of average build and experience.
CharacterDelivers old-school vibration, mechanical character, and a raw connection to the road that modern bikes rarely offer.
Not Ideal ForNot the right choice for riders seeking modern performance, long-haul comfort, or off-road capability.
