Replacement Forged Stroker Pistons<br />
For 1972-’85 Harley-Davidson ® Ironhead Sportster ®<br />
These 33⁄16" bore stroker pistons are designed to be used in conjunction with S&S 45⁄8" stroke<br />
flywheels to convert 1000cc Ironhead engines in 1972-'85 Harley-Davidson® Sportster® models<br />
to 1200cc (74") displacement.<br />
These pistons can also be used to replace pistons in older S&S stroker engines with 41⁄16",<br />
49⁄16", 41⁄2", and 413⁄16" stroke flywheels. All clearances must be checked. See chart below for<br />
displacements and compression ratios. These pistons are normally used in stock Harley-Davidson®<br />
cylinders. No cylinders are available from S&S for Ironhead Sportster models.<br />

NOTES<br />
If replacing the pistons in a older 77" stroker engine, stroker plates are required, and all clearances must be checked.<br />
S&S offers machine shop services through the S&S Service and Speed Center. New pistons can be fit to your existing cylinders for a reasonable charge.<br />
