PM 112x6B LH Caliper chrome 84-99

These "112x6B" type compact 6 piston differential bore calipers are designed for use with stock or aftermarket 11 1/2" disc rotors, but also available for use with 13" aftermarket discs. This direct bolt on caliper has its design roots in endurance road racing which showed the need for differential bore sizes use a larger trailing piston to compensate for uneven pad wear under high heat applications. PM has introduced this technology in these 6 piston calipers. The differential bore system has been race proven and is ready to give you the best feel possible and smooth powerful braking. Single or dual, this is the very best front brake set up anywhere. These calipers bolt straight onto the stock lugs on the front fork. Order 1 left caliper for single disc and 1 right and 1 left for dual disc application. Sportster 2008-2013 models require a brake master cylinder with 9/16" bore for single disc or 11/16" bore for dual disc.
