A good 07 R6 with a pipe and careful mapping does about 117-119 rw. A R3 with 150RW will not go as fast because a) it has the aerodynamics of a brick ****house, b) the R3 has less torque at 6000 than it does at 2000rpm. c)the R6 will do 16000 rpm and is geared to suit and has max torque approx 14500 it is also 165kgs dry intead of 345kgs dry. Disclaimer,weights and rpms may not be exact due to memory
Also the R3 is speed limited to 220kph unless you Tuneboy it. With the amount of torque the R3 has a different way of testing the bikes would be to fit a fat chick to the back of each one ,then add a trailer and bags and enough gear for a 4 dayweekend,then see who wins.
