It all started over 50 years ago when my father, George J Smith, tested his own go-fast parts on his Harley at the local dragstrips throughout Illinois and the punishing high speed runs at the Bonneville Salt Flats. S&S designed parts proved their superior performance at the race track. We continued that heritage throughout our history. Today, about half the qualifying field of 16 bikes at each NHRA Pro Stock Motorcycle National Event are powered by S&S v-twin racing engines. Those bikes have wons national championships two of the last three seasons. That’s “Proven Performance!”

At S&S Cycle, we are committed to designing and producing the best parts possible for Harley-Davidson® motorcycles. Parts are conceived using the latest 3-D modeling software, and initial prototypes are often made on our rapid protyping machine. The parts are tested at the track, a number of different dynos, several engine endurance test stands and we put on a lot of good old-fashioned road miles. Sometimes we break things on purpose just to see what it takes. We always learn something from it, and that makes our parts better. We use the best materials available, and machine our parts on modern CNC machining centers to ensure the highest quality and the best value for our customers. Our quality control department also uses state of the art digital measuring equipment to make sure our parts are made to rigid specifications and tolerances.

In spite of all these efforts, once in a great while, a bad part gets out the door. Unfortunate as that is, anyone who has been involved in manufacturing knows that it can happen. It's just a fact of life. What separates the men from the boys is how the situation is handled should it arise.

Here at S&S we have built a reputation on performance and quality. With our exhaustive testing program, we know how well our parts perform. After all, our company motto is Proven Performance®. But there is another aspect to Proven Performance that has to do with how we do business. If a customer has a legitimate problem with an S&S part, we will take care of it. Period.

We maintain a full time tech staff, and these are some of the most knowledgeable guys in the industry. In a lot of cases they can correct potential problems right over the phone. In the event that we do need to get a part back for inspection or repair, our remanufacturing department is well equipped to handle just about any situation that may arise.

What this means to you is that you can buy S&S products with confidence. We want you to be happy with your purchase, and we will do our best to make sure you are. Great parts and great service. That's Proven Performance too.
