S&S Cycle

S&S Cycle

What started as a passion for speed, grew into the best known company name in the V-Twin high performance aftermarket. George J. Smith 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 La Crosse, WI.

S&S Cycle, Inc. has been in the v-twin high performance parts business for over 50 years, specializing in motorcycle parts like high performance motorcycle kits for Harley-Davidson® motorcycles. We manufacture a complete line of motorcycle performance products ranging from motorcycle slip-on exhaust, bolt on performance intakes, motorcycle big bore kits, or a complete motorcycle engine.

Although we are known for Super Series of performance carburetors and for motorcycle engines, S&S Cycle, Inc. proudly offers sidewinder big bore kits, our stealth motorcycle air cleaner kit, and many other ways to help you get more horsepower and torque.

S&S is currently featuring a full line of performance exhaust for Harley® including our touring exhaust.  Coupled with S&S Cycle's new performance headers, you ensure that your motorcycle exhaust system is performance orientated and great looking.

For the late model performance rider: Everyone needs to take that first step! S&S offers a logical, cost effective 4 step plan for performance increases.  These range from small steps like mufflers and intakes, or getting more horsepower out of your motorcycle engine with big bore kits and more. 

For the Vintage enthusiast: With over a half century in the business, we know vintage and we have the products to prove it in our motorcycle vintage parts offering. With our age also comes experience and the reputation as one of the most trusted names in performance v-twin parts and motorcycle engines for Harley-Davidson® and other American v-twins.
