joe has seen many threads on tyres, in the process this summer of having my track days and feeling like I was testing the limits of traction available
I happened to have a conversation with an interesting fellow at the race track and he talked as if he knew his stuff,
he went into great explanation about the effect that a big V-twin has on a rear tyre, he stated that the twin has more torque and that all tyres were not
suitable for the ass of a twin, some were actually designed for them, some would not weather as well,
I can definitely see the difference a in line 1ltr has on a rear and front tyre opposed to the SD.
