S&S Cycle Motorcycle Parts

S&S Cycle is one of the most recognized and respected names in the v-twin business, trusted worldwide for best-in-class high-performance parts for Harley-Davidson and other v-twin bikes. The company was born from a passion for speed and the desire for better engine parts for v-twin motorcycles that grew into a leading manufacturer of high-performance parts. Started with an offering of lightweight pushrod kits in late 1958, S&S Cycle has expanded its product selection to include complete motorcycle engines and exhaust systems, cylinder heads, carburetors, camshafts, fuel injection systems, stroker kits, big bore kits, service replacement parts, and many more.

S&S Cycle has been synonymous with drag racing and Bonneville land speed racing for over half a century, providing racers and race teams of all levels of competition with high-performance racing parts and accessories. Having equipped their bikes with S&S Cycle complete engines or performance parts, they have set numerous national and world records, including more than 16 Bonneville national records. Today, just like many decades ago, the company is still driven by a passion for powersports, bringing to market innovative high-performance solutions and ideas to make both modern and vintage V-twin bikes run faster and faster.

Being at the leading edge of innovation, S&S Cycle strives to design and manufacture top-quality products that are not only high-performance, but also in compliance with emission standards. To make this possible, it has developed its own emissions testing laboratory to test all v-twin bike parts and components for matching nationwide and local emissions standards. This allows S&S Cycle to provide non-professional riders with high-performance yet street legal emissions compliant products, so they can enjoy superior horsepower and torque virtually anywhere across the globe, even in California, where its laboratory is approved by the California Air Resources Board for testing of aftermarket products on motorcycles.
