I totally enjoyed my '02 Hayabusa when I had it...the suspension was tweaked a little and I could take corners fairly well. But in comparison to the much lighter litre bikes that I've owned, it was much more to manhandle in the twisties.
yes,,its much harder to take tight corners on the Busa ,,,thats for sure.,..their weight shows itself as soon as you go from high speed sweeper.or medium radius corner,,to the tight tricky stuff
