Just in case anyone was wondering how the BT 010 perform I thought I would pass this along. TRY THEM. I have always ridden on Dunlop 207's with one set of Avons and although the Dunlops are a good tire when you get aggressive with them their flaws, especially with the R1, come out. The biggest problem for me has always been the stability of the tire at full lean. They tended to wobble slightly and it was difficult to hold the exact line I wanted. Now don't get me wrong I am not in any way a racer. There is an area by my house that has been turned into a road course by the riders that frequent the area and it is a lot of fun. The BT-010 though has no instability at lean. The bike leans almost effortlessly and even hard on the throttle at the exit did not wobble the tire. The stability at high speed in a straight line even seems slightly better. I do not know how well they will last but I do know that the tire showed little if any wear after 37 miles of hard cornering and acceleration. They also seem to warm up quicker. The sizes I run on the R1 are 180-55-17 rear and 120-65-17 front. Just thought I would pass this along.
