About This Product
MCS replacement cast piston, plus seventy thou oversize. Fits 1941 to early 1978 1200cc, seventy-four cubic inch, Knucklehead, Panhead, and Shovelhead Big Twin engines with significant bore wear. Standard 8 to 1 compression ratio. This is the largest standard overbore before you need new cylinder sleeves or replacement barrels. Cast construction has low thermal expansion and costs less than a forged OEM piston. Wristpin and clips are included. Rings are sold separately. Check bore size and compatibility before installation. Standard break-in applies.
Manufacturer part number: 504455.
