I just out a brand new set of piot powers on saturday,, derbycles.com has them for 110.00 for the rear and 73.00 for the front thats the cheapest ive found michlens on line anywhere,, and theres no tax and free fedex shipping two brand new michlen z rated pilot powers at my door step for 183.00 yee ha,,,,,,, P.s I noticed in the past if I had a bike push in a turn the tire pressure was low ,, I think mine calls for 42psI front and back,,,,could be what your problem is,,,,but i would still slap on 2 new ones for that price,,,plus their brake pads are 29,00 a set for the front { EBC}
check your tire pressure,,I bet its low
