After the latest evolutions, the original Honda engine is now greatly improved, especially at low steady states. This bike's strong point is the ease with which you can use the delivery. Even an amateur feels immediately at ease on the track with a bike like this.?However, medium steady states are where we feel the need for something more, without distorting this bike's soft, sweet personality.?
