750768-BX-LB1 Pistons 1200CC XL 010

Drag Specialties replacement pistons are sold as a pair for XL 1200cc Sportster engines, sized at 3.498 inch bore with plus 0.010 inch oversize and a 9 to 1 compression ratio. Cast aluminum alloy construction suits the heat cycles of air-cooled Harley-Davidson v-twin operation. Each piston comes with wrist pins and circlips, forming a complete set for top-end reconditioning. Drag Specialties machines these to precise tolerances to restore lost compression and reduce blow-by in 1200cc Sportster motors. Choosing this plus 0.010 inch oversize allows machinists to clean up minor cylinder wall damage while retaining factory compression height and ring pack location.
