Yamaha 750

To this I'd have to point out the extreme differences in the performance level from just about 5 year old bikes to todays models.

Say about a '93 600 rocket will make right around 65-70hp. Today they are making between low and high 90's. That's a huge difference. The early 90's 750's I've seen make about 75hp. The new ones make in the low 100's.

The last stock dyno I've seen on a 900RR was just plain pathetic. 117hp max, the Ninja ZX9R made 134hp. That's a huge difference. The Hayabusa on the dyno made 154hp. Keep in mind, these are RWHP numbers. The 900RR is just plain doggy compared to the Ninja, which as unbelieveable as it seems made over 120hp for 3500rpms. Just as long as the Hayabusa did. The 9R pulled so strong and so flat, unreal, the 'Bus of course would have managed it longer, but you run out of rpm's to keep pushing. Of course if you were to say, ahem... put a 997 big bore kit and play with the 900RR motor a little, I've seen it change from the stock numbers to numbers that challange the Hayabusa.

Even a well driven near stock 5.0 can hang with a early 90's 600 on a roll above 40mph. I can usually beat them. The 750's would of course be more difficult, but it's the hole shot and 0-60 that gives them such a huge advantage.
