It was just a few weeks ago that we told you how Pirelli was making purpose-built tires for the 300cc racing category, and now we get word that Dunlop is doing the same. 

Creating the all-new KR448 front tire, and KR451 rear tire in sizes and compounds for bikes in the 300cc to 400cc range, Dunlop its making sure that it has a firm grip on the small-displacement categories that are filling grids on race tracks around the world, but especially in the United States.
