Because they put out 260 RWHP @ ~300 lbs out of a 990 CC V-4/I-4/V-5 motor. All the stuff that's used to make one is best of the best, the least expensive bike is about 1/2 million bucks I belive. They constantly fight for performance and traction with these bikes. The AMA bikes are basically show room bikes that are tweaked with aftermarket parts. Superstocks and Supersports are very close to stock bikes, while Superbikes are little more modified for power, putting out about 190-210 hp at rear wheel.
its a different engine design too..."growler engines"
plus the fact that people of normal size cant really fit on them because they're so small. for example...a lot of people say ben spies will never get to motogp because he's too big, but he can still fit on an AMA bike.
they're also called big-bang engines. from what i understand (which isnt much) the engines are 4 cylinders, but the 2 inners fire simultaneously and the 2 outter ones fire simultaneously. they're too much for the street to be made reliable.
i read about it on speedzilla. if you want, you can go there and search growler engines and it'll take you to 2 threads on them. the $80,000 ducati coming out in a few years has this technology.
i guess it just makes more torque along with high revs and higher horsepower. not sure though.
Gotcha. I've heard of big bangs, just never heard of them refered to as growler.
I think the switched to firing the two inners at once, and the outer sequentially. The idea is to give the rear tire more "idle" time between power pulses to regain traction.
Has anyone had an issue with Honda burning oil (i'm guessing it's burning it, because there is no leaks in sight anywhere) Bike has 6K miles on it and a two brothers slip on exhaust. There is some carbon build up on the end of pipe after riding for an hour or so. The bike seems to be running...
Well that worries me abit. I'm conserned how all this data is going to be used. Of course many others will argue against the existance of the system itself.
Luckily for some of us, the expance of putting something like that in the states will keep it from happening for quiet some time.
