Big Bore Piston Kit 1200cc 10:1 For Harley-Davidson Sportster Evolution Sportster 883

Wiseco Big Bore piston kits will convert the Evolution 883 engine into a more powerful 1200cc engine by simply adapting the stock 883 cylinders.

Wiseco forged pistons are stronger than stock Harley pistons and will give you greater increases in horsepower and torque with complete reliability.

Just mount the engine with the original 1200 gaskets and that's it. There are no modifications to the cylinder heads and no crank rebalancing is necessary.

Wiseco 1200CC kits contain a pair of matched and balanced precision forged pistons, Hastings piston rings, wrist screws, circlips, and instructions.

Note: Cylinders on 2009 and later models cannot accept these 3 1/2" pistons. You will need to order two new OEM cylinders from 2004 thru 2008 XL1200 models or a pair of S&S 3 1/2" cylinders separately.
