I can speak from a drag racing point of view meaning take away all the gear changes.best start, best rider etc. because at times when I get messed with Bigger bikes or other 1ks even though I weigh 200lbs and it turns out to be just a bike vs bike at the end after the 1/8th mile and the 10R is even or close as well then the Power/weight ratio must be in play and Monster Motor, I have been side by side on my last gear in the 1/4 mile after the 1/8 mile against BusA's, ZX14s, Gix 06/07s etc. that weren't to modified against my pure stock ZX10R trying to get to the finish line first or LEAVE me and the 1st Gen just says NO NO NO your not going to LEAVE me I will stay with you or BEAT you. That my friends is an Awesome bike that is over 5yrs old and proof the Motor speaks for itself and has the Attitude and performance that will be recognized many years later ... a true classic and the main reason I haven't modified or upgraded to another make or model year especially when I can go to my local drag strip with my old stock bike and raise some noise to this day. :wink: :thumbsup:
