I have just put on my 4th PR2 rear and am getting ~10 000km to a rear and actually wearing the sides out before the centres
I was thinking of trying the Conti Road Attack after some good things from guys over east on OzBB but the distributor here in West Aus only has the lower spec ones not the "C" spec for heavier bikes and they are $20+ a tyre more expensive
The road attack is by far the best sport ouring tire for grip. Cranking the throttle open leaned over in 2nd and it just rocket. Knee draggin,2 up knee draggin,2 up loaded ith luggage knee draggin,rain,wheelies,my insane 170mph morning commute,never gave me a problem with grip. Only thing is the front and rear were both toast at just short of 2500 miles. The front was worn flat on the left side and was unbalanced enough to cause massive headshake when you take your hands off the bars. The rear was almost down 2 the chord. I'm sure without powering the front up, and taking off like a jack(ass) rabbit from evey light and riding a few minutes a week at a legal rate of travel would help. Should be good for 4K miles with a older brain controling the throttle. I sent you a pm of my morning ride 2 work,6 days a week and a diffrent one showing grip right afta an insane rainstorm.
