Ok, lets set this straight, neither the Hyabusa, ZX-12R, YZF-R1, nor the GSXR-1000 can top 200 off the show room floor. The fastest measured stock street bike was the first run of Hyabusa's at 197 mph (maybe 198, I can't remember exactly). The only "production" motorcycle to ever break 200 mph was a special edition Bimmota (sp?), and by limited I mean only about 20 were ever made.
In order to reach the outrageous speeds claimed by several members of this thread, you need to add a turbo and other go fast goodies like water injection. Steve Kinzer (of Mr. Turbo corp) had the fastest street legal motorcycle for a while, it was a turbo charged and water injected ZX-11 that did 230+ mph, measured with radar and timing lights. Currently, there is a company in Louisiana which makes turbine (helicopter jet engine) bikes for around $90,000, Jay Leno has one. These are theoretically capable of close to 300 mph buy no one has had the balls to hold the throttle open long enough. Supposedly they do 100 - 200 mph in under 10 seconds.
TomC25,
Yep, open class bikes are down right scary these days. Nearly all current liter bikes will do 0 - 100 mph in 6 seconds, 1/4 mile in 9.8 - 10.2 sec, and top out above 180 mph. I had an older liter bike ('88 Katana 1100) and it was a blast, especially because I had it repainted without any stickers so all of these little 600's would come up beside me and want to race. I'd let them take off, follow just behind them at about 8/10's throttle, and then around 120 take if WFO pass them with a wave. And my bike only had about 125 rear wheel hp, the new bikes have 145+ hp and weigh 150 lbs less, gives me wood just thinking about them 😀
