Want more power and better response from your V-twin? S&S Cycle is a well-known name among Harley-Davidson owners and custom builders looking to upgrade their engine.

American V-twin performance

S&S Cycle is an American manufacturer with long experience in performance for V-twin engines, especially Harley-Davidson and engines in the same style. The brand is known both for complete engines and for the individual parts that make a stock engine stronger and more responsive. Many custom builders use S&S parts as the foundation for their projects, because the range covers everything from intake and carburetor to camshafts, pistons and exhaust.

S&S Cycle's key products

Air cleaners such as the Stealth series are a popular first upgrade that lets the engine breathe more air. The S&S Super E and Super G are classic carburetors for V-twins, and the camshafts come in several profiles depending on whether you want more low-end torque or more top-end power. The range also includes exhausts, big bore kits, pistons, cylinders, and oil and engine parts. See each product for the engines and model years it fits.

Frequently asked questions

Does my engine need tuning when I fit an S&S air cleaner and exhaust?

It is often a good idea. When the engine flows more air in and out, the air-fuel ratio changes, and adjusting the carburetor or fuel injection usually gives the best running and durability.

Which camshaft should I choose?

It depends on how you ride and what else the engine has. Some profiles give more torque low in the rev range, others more power at the top. Check the description on each product, or contact us for advice.
