I have to say I was VERY disappointed with the gen 3 hayabusa. I don't use electronics so I can't see paying that much more for a bike with basically the same power. I know there are other improvements but just not enough for me.Nothing wrong with going ahead with that plan . IMO , you are free to pick a bike you like , and do what you want , to your taste . In regards to the Busa , it can be built to run a drag strip , roll a race , or go super HP like @michael parris heuberger and do all these and the top speed events . Then there are dudes that like the big bike feel , the torquey big cc , and decide we will build it to turn better and mod it accordingly . Some like you @bigboy , going further than myself for the engine build also , full house mods .
The stock Busa gets gapped by these new liter bikes. It needed a bump in power but not too much to make it unbalance. Especially with keeping stock wheelbase and height
