About S&S Cycle

The performance aftermarket, both 2 and 4 wheel was born on race tracks around the world. Enthusiasts in their single car garages grinding aluminum and welding steel late into the night, all in the hopes of a quicker ET or a higher top speed. For many it stayed on the local tracks, a select few translated their passion for performance into global enterprises. In 1958 George Smith chose the latter and across the next sixty plus years S&S Cycle would mature from grassroots racing effort to world class manufacturer and OEM partner. All the while racing has remained a core competency, from speed records at the Bonneville Salt Flats to multi year championships in American Flat Track, S&S is the go to for high performance on and off the race track.
