Guys
I have stayed with the factory fitted Pilot Sports as they have proven to be great in all weather conditions and on all types of surfaces. I get 3.5k out of the back and then it wants changing (by 4k it's illeagal and wobberly) and the front get a good 6k with another 500miles for reminding me to change. My advice to nay rider is to stick with what gives them the most confidence - (confidence leads to safer more enjoyable riding) - even if you get a couple hundred miles less out of a tyre than the next guy.
Oh and the other thing I've discovered after 35yrs riding all sorts of bikes is that folks have a habbit of claiming fantastic wear rates for things like tyres, brake pads, clutch linings etc etc
