Zipper’s has developed new aluminum alloy cylinders for 883 and 1200 engines to increase the engine size a little or a lot! These cylinders are manufactured with high quality cast-in iron liners and will work in all types of performance applications. Bore sizes available are 3-9/16” (1250cc on the stock case), and 3-13/16” (88” with stock stroke, 99”, requires 4-5/16” stroker crankshaft).

Can be fitted with your choice of several piston designs (see catalog or web site) to accommodate specific usages, or you can purchase these cylinders un-sized to fit your pistons. Includes design improvements for structural integrity, plus cooling fins have been increased to improve heat transfer.

Note: Cylinders for XB9/12 models and 2004-up Sportsters® have 1/4” more fin circumference to match the newer cylinder head fin configuration.

Zip Tip - 3-13/16” is the largest bore size that the stock H-D® XL cases can be safely bored for. 3-5/8” bore is the maximum S&S replacement XL/Buell cases can be bored for.
