Actually most of the higher horsepower motorcycles have an OEM specially made tire. Like the "J" battleaxe for example, Bridgestone made this "special" tire to handle what the busa puts out, yet you wouldn't know listening to everyones stories. In my opinion, the Bridgestone is a very hard compound with sidewall stiffners and is probablly the only tire that will give good milage and decent grip on heavy high HP bikes! It's too bad Dunlop didn't get to make the OEM tire. It doesn't take long for al the aftermarket companies to get their hands on these OEM tires. Go into any dealer and look at the tire section in their aftermarket catalogs. you will see pages of OEM tires, Bridgestone/Dunlop have a ton! Personally, when I get my busa, the Bridgestones will be sold with no milage on them!!!
