About S&S Cycle

S&S Cycle has built American V-twin performance parts in Viola, Wisconsin since 1958 — flywheels, carburetors, cams, cylinder heads and complete crate engines. When a Harley owner talks about a 124, a 128 or a 131 build, they are usually talking about S&S. Few names carry more weight with engine builders in this space.

S&S Cycle Power Packs combine big-bore cylinders, a matched cam, cam plate, and oil pump to deliver high horsepower without custom machine work. The 4.32" bore cylinders are paired with everything needed for reliable cam chest performance on Harley-Davidson engines.

100 kit is sick! 10/5/1 compression is perfect for the 585 cams. Not going to burn the tires unless you bounce it, but at 2.7 K it pulls like a freight train. Super fun! Thanks S&S!
