Running Pilot Road series for quite sometime on various bikes.
Can't say good enough things about them. Good wear and street performance.
My current Hayabusa is a rear tire eater, PR holds up well. My estimate, 5-7K with aggressive riding, upwards to 10K if taking it easy and touring/commuting only.
Pretty good for being fitted on a high torque bike.
I hear good things about Avon Storm series also.
