I think it's utterly pointless comparing a road legal racing bike with an out and out, two seater sports Tourer.
One is small,light, nimble and fast, the other big, heavy and not designed to be as nimble or as track fast. Instead of this endless, tedious comparison of horsepower and the lack of competitiveness of the G3, let's ask why can't a sports bike take a pillion And hard panniers?
The hayabusa can.
Why is a sports bike so relatively uncomfortable to ride all day on the motorway or for extended periods of time?
The hayabusa isn't.
Why do sports bikes, and other sports tourers such as the h2sx, have such poor torque low down?
The hayabusa doesn't.
Why don't sports bikes have bigger fairings and screens to help keep the rain and wind off?
The hayabusa has.
Why don't sports bikes hold any drag or LSR records?
The hayabusa does.
