As far as four strokes go and i do like the low down power of the big ones,if they make 125cc 2 strokes compete against 250 four stokes etc in some classes,what show is a 147 kg honda 650 going to have against a 99kg 500 cc 2 stroke - No Show and same goes for the latest 450's the weight and extra stokes required to produce power lets them down big time against the ledgend,i guess that is why kawasaki continued to go with the same receipe for 14 years nothing could touch the lime green beast over that time and nothing still can that i am aware of.
If you want to go to
www.racetothesky.com you will see the overall performance of the mighty 5 in the results link,top bike and a 19th overall finish against bikes and cars etc with purchase prices thousands of times more - Craig Hyde the rider contributed big time too, but if he was on a honda 650 he proberly would not have even been in the top 100.
