S&S Cycle has been in the business of manufacturing high quality, high performance engine components for over 50 years. What started as a passion for speed, grew into the best known company name in the V-Twin high performance aftermarket. George Smith Sr. had to build his own parts to make his motorcycle faster. Now the company he founded manufactures the most prestigious line of "go fast" v-twin engine parts in the world. The company was started in the basement of his home in Blue Island IL in 1958, and moved to Viola, WI in 1969. In 2004 an additional facility was opened in LaCrosse, WI.
