my m50 sports is 187 pounds dry weight compared to a maxis 87 pounds
plus I weigh 14 stone - 196 pounds
so am I gonna see the 60 plus mph out of my kitted bike with mediocre exhaust?
or is the weight gonna mean I aren't gonna see those speeds unless I do some porting and get a good pipe?
I am now getting 47mph into a head wind and 54mph back wind (but it was still accelerating prob to 57?)
