Well last year I posted the results on some pulls we did my brother and I. His 05 ZX-10 is now all nicely broken in and ripping. All he's got is a Yosh bolt-on vs my Busa with bolt-ons and pc. The results of our pulls this time around were depressing. I thought I'd be smoking him like I did last year and that was not the case, as a matter of fact it was the other way around, almost. He weighs 195 and I weigh 170 so if you factor in the extra 100 pounds on the busa it only comes out to 75 pounds. We switched bikes just to make sure and that freaking thing rocks. We did a roll-on in third to about 170 and I'm sorry but that story about the Busa streaching its legs at 140 or so vs. a liter bike is crap. That damn ZX-10 was with me the whole way, as a matter of fact in some of our pulls if he got on the gas just a tad earlier than me it was over. Belive me guys, I'm no sissy and I've been riding for a long time those liter bikes are right there if not already past the performance of a Busa. On the plus side of all this is there is no replacement for the low end torque on the Busa although 80lbs. of torque on the Zx-10 is nothing to laugh about.
