4 Rating

A Beautiful Bike for Smooth, Relaxed Rides

I love this bike because it combines an old school look with modern engineering. The massive 1200 cc liquid cooled engine gives you plenty of smooth power right when you start moving, and it stays nice and cool even on long trips. On the highway, it feels very stable and can easily reach a 190 kmph speed, making long distance journeys feel effortless.
