The 748 SP is a great bike,but you have to work it like hell (on the road...)to get the right performance!The usual problem is the "dip" underneath 6000 rpm , I have managed to reduce this with an bigger rear sprocket and a chip-install.The dip however is still there,but it´s overcome within seconds!Keep the rotations up to 7000rpm and more however and who will follow....?(it keeps up even 916´s)
