Kamikaze, what parts that are actually "stock" are you referring to on those Pro Stock bikes? Engine, trans, clutch, tires, chassis, suspension, gas tank... or should I say fuel cell, carbs, wheels, brakes, etc...?? I mean, I can go to my local dealer and buy those bikes, right? How about any of those parts? No relevance at all to the bikes we are buying now, nor should those bikes influence our buying decisions for today. Rather a closer look should be made to the Prostar 600 cc classes and Pro Superbike classes.... then ask yourself who rules those? Don't burn your brain too much on that one..... can you say Green?
At least those bikes resemble somewhat of the type of machinery you can buy today. O.E.M. blocks, trans, frames, heads, etc.
