One of life's greater pleasures is to get on a powerful motorcycle and get some fresh air. You do not have to ride fast, it is better to do it neatly and smoothly.
One of the best motorcycles on the road is the Honda Pan-European, otherwise known as the ST-1100.

If you think that 300 kg is a bit on the heavy side, try an MZ instead.
