I have a local road they might as well call "Tar Snake Road" There are as many tar snakes as pavement and I've complained to the local city about it..its THAT bad. Anyway, I took my brand new pr2's over it today, at about 80 degrees. The feel sucked. No scary moments, just not comfortable. With a heavy bike, soft tar, etc.....I dont expect much. Even my sv suzuki with roadsmart II's on it was bad.
