The gsxr 1100 I race is stock except for a header and D&D pipe. I´ve only run this bike at Bristol TN dragway three times now and ran a 11.2 sec quarter at 126 mph last night. I know this bike is capable of mid to high 10 sec quarters. If your looking for a great handeling fast bike and you want to run with R1´s GSXR 1000´s ZX 9´s 10´s and 11´s , get one. It has 155 HP at the crank and a massive inverted front fork, Wheeley it all day long...lol
