Wiseco Piston Kit 883-1200 9.5:1 .020

Wiseco's Big Bore piston kits will convert the 883 Evolution engine into a more powerful 1200CC engine simply by boring the stock 883 cylinders. Wiseco forged pistons are stronger than the stock Harley pistons and will give you a major increase in Horsepower and Torque with total reliability. Assemble the engine with stock 1200 gaskets and off you go, no head modifications or crank re-balancing required. The Wiseco 1200CC kits contain a pair of precision matched and balanced forged pistons, Hastings piston rings, wrist pins, circlips and boring instructions.

Note: The cylinders on 2009 and later models can not be bored to accept these 3 1/2" bore pistons. You will have to order 2 new Stock 2004-2008 XL1200 cylinders or a pair of S&S 3 1/2" bore cylinders separately.
