So lets say that a gsxr 1000 decides to run the biggest motor of 1242 (5 x 6) / 2.62 = 474 pounds - 150 pound rider is a 324 pound bike (doable) but if a 200 lb guy builds one he has to have a 274 lb bike (prolly not likely)!! But yet lets says a busa builds a max motor of 1679 (5 x 11) / 2.62 is 640 lbs - 150 lbs rider is 470 lb bike (doable). But now lets says that a big boy wants to race and the biggest motor he can build is a 1679 but yet he weighs 220 suited, he now needs to build a 420 lb bike (that's pretty light!).
So what I am saying is a light rider is allowed to build a light bike of 470 lbs, while the 1000's and big guys on busa's have to build REALLLLLY light bikes to compete. Now I don't really know busas and their weight seeing as I race my 1000 all the time, but 420 lb busa seems really light and if the guy weight even more, it aint happening. Thoughts?
