S&S Cycle logo

When a legend is not enough.


Located in Viola, Wisconsin, we're just down the road from Milwaukee. S&S Cycle has been building high performance parts for Harley-Davidson® motorcycles for over 50 years. That History of Proven Performance® is our legend. We Prove it at the racetrack, on the dyno, and on the road - because reliability is just as important as speed.

S&S performance parts are available at cycle shops and select Harley-Davidson® dealers around the world. Ask for them by name to get authentic, American-made, S&S performance parts.

Let S&S bring your legend to life.

Lifestyle

The awe inspiring view of a sunset is a moment to be savored, but the experience of getting there is just as important. Style and chrome won't get you up that mountain road or safely past that semi. Only torque and horsepower will get it done. S&S® Cycle gives you more of both.

There are many ways to fulfill the lifestyle. S&S has a full line of apparel to help you dress the part and show your S&S pride. And for our fans of the vintage lifestlye, the Flathead Power brand offers it's vintage motorcycle online forum to connect to others living the lifestlye.

Performance

It's best to keep the competition behind you, so you can watch them in your mirror. Style and chrome won't keep you in the lead, but it's easy to stay ahead if you have the power. S&S gives you pack-leading power and dependability too.

If you have a new bike and are considering high performance modifications, the expense can seem pretty daunting. However, if done one step at a time, with our 4 Step process, these modifications can be pretty affordable.

Keep up to date on the world of performance; S&S introduces the "Performance Times Blog" with news, pictures, videos for what's new on the street and the strip.

Competition

Burning rubber and breaking record speeds on the dragstrip require torque and horsepower. Style and chrome don't set records, but add high performance parts and you've got a winner. Whether you race in a street class or in NHRA Prostock, S&S® Cycle gives you more power.
