my bro has avon's on his HD and loves them. my strat came with dunlop and i didnt care for them. i bought the bridgestones to replace the dunlops when they wore out (5000 mi)and omg what a difference. they grip like crazy compared to the dunlops. i could spin the dunlops at will but the bridgestones stick like glue, i have gotten the front wheel up quite a few times trying to do burnouts from stop lights. caught me off guard. front tire off the ground 6 - 8 inches for about 30 feet.
