ma mate has a runner sp and has just bought a doppler s3r exhaust a polini kevlar belt and a polini variator it does 50-55 without them, what speed should he be doing with them on??
to be honest jamie ur being a bit unrealistic.. with those parts he listed its more around the 100 region..
Lots of useless spam in this topic. You mates bike will do 45-50mph true speed with the parts you said. End of.
