What is an S&S Motorcycle Engine?

S&S Cycle is a well-known motorcycle engine manufacturer established in 1958 by Stanley Stankos and George J. Smith. The American company entered the market by selling aftermarket pushrods for Harley motorcycles and then slowly expanded over the years. Today, S&S Cycle designs and produces a wide variety of aftermarket motorcycle parts like clutches, exhaust systems, performance kits, and complete “bolt-in” engines.

Since its founding, the company has been one of the most well-known motorcycle engine manufacturers in the marketplace. Besides cruisers, S&S engines appear in Morgan 3-wheel cars as well.

Although S&S Cycle always had a strong relationship with Harley-Davidson, this cooperation didn’t always go smoothly.
