MCS Pistons

43 products — part of all Pistons

MCS pistons cover Harley-Davidson engine displacements that are often missing from modern aftermarket catalogues — the 1941 to early 1978 1200cc and 74-inch engines spanning Knucklehead, Panhead, and Shovelhead generations in a single listing, the 1957 to 1971 XL900 Sportster (the original XLCH displacement before the XL1000 arrived), the 1972 to 1985 XL1000, and the 1988 to 2003 XL1200. The 1984 to 1999 1340cc Evolution Big Twin is also covered. Getting piston specification right on a Harley-Davidson engine rebuild requires the correct compression height, ring groove dimensions, and dome profile for the specific bore and cam combination — MCS provides these at the displacement level rather than just by year range, which is what a rebuild actually needs. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks MCS through Iron Stable. Browse the full MCS Pistons range below.
