S&S Cycle, Inc. is an American motorcycle engine and parts manufacturer that was founded in 1958 in Blue Island, Illinois. In 1969, S&S moved from Blue Island to establish a new headquarters in Viola, Wisconsin. S&S still operates at this location, but opened an additional facility in La Crosse, Wisconsin in 2004. S&S started by selling aftermarket engine components for Harley-Davidson motorcycles, and today they manufacture the most prestigious line of "go fast" V-Twin engine parts in the world. What started as a passion for speed grew into the best known company name in the V-Twin aftermarket motorcycle industry. S&S has been building high quality, high performance engine components for Harley-Davidson motorcycles for over fifty years. Visit www.sscycle.com for more information regarding S&S Cycle and its family of high performance aftermarket S&S motorcycle engines and engine components.
S&S Cycle has been in the v-twin high performance parts business for over a half century, specializing in motorcycle parts like high performance motorcycle kits for Harley-Davidson and Polaris-Victory motorcycles. S&S Cycle manufactures a complete line of motorcycle performance products ranging from motorcycle slip-on exhausts, bolt on performance intakes, motorcycle big bore kits, or complete motorcycle engines.
S&S Cycle was the first motorcycle engine manufacturer to produce pre-certified United States Environmental Protection Agency compliant engines, lifting the burden and cost of performing the complicated EPA testing procedures from the companies and enthusiasts who buy S&S engines. The company also produces TÜV certified engines, and has even succeeded in complying with California's unique emissions requirements.
With over fifty years in the business, S&S Cycle knows vintage and has the products to prove it in its Flathead Power motorcycle vintage parts offering. With 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.
Although S&S Cycle is known for its Super Series of performance carburetors and for motorcycle engines, S&S Cycle proudly offers sidewinder big bore kits, the distinctive teardrop motorcycle air cleaner kits, and many other ways to help you get more horsepower.
S&S Cycle 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.
S&S Cycle has high quality aftermarket products for late model Harley-Davidson big twin motorcycles that allow for motorcycle performance upgrades that can be done in steps. This allows riders to use the parts they purchase in the early steps to compliment the parts they add in the later steps. There are several advantages to this approach. First of all, you can go faster right away, without having to pay a huge bill all at once. Then, as your budget allows or as your lust for power demands, you can go to the next step (also affordable). And of course, this way, you always have something to look forward to... the next step!
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, these modifications can be pretty affordable. Here is a series of performance upgrades that can help you go fast and will fit any budget. The idea is to install some key components that will give you more power right now. Later, installing additional parts to what you already have will produce even more power. That way, you can build up to a respectable level of performance without having to make a large investment all at once. Of course, you can start at any step you want to. If you want the big numbers right away, just go for it and get everything at once.
One of the most cost effective ways to improve motorcycle performance is a high flowing air cleaner kit and a set of high performance slip-on mufflers from S&S Cycle. These parts are also required components of any more serious performance package.
The addition of cams is the next step toward higher motorcycle performance. Several types of cams are available, and it is important to decide what cams are best suited to your immediate needs and what cams will be needed to achieve your long-term goals. If you can choose cams that will work for both, you will save money. For more torque we recommend the S&S 551 cams for dressers, and the S&S 583 cam for Dyna and Softail models. For more top end horsepower, S&S suggests the S&S 585 cams. Dealer installation of cams is recommended, and EFI tuning is generally required. S&S recommends the Harley-Davidson Race Tuner or Dynojet Power Commander for EFI tuning.
You don't have to pull the heads to change pushrods. S&S Cycle came up with a design that allowsinstallation and removal by just opening the pushrod covers. S&S has Quickee pushrods available for Harley-Davidson Evolution big twin and Twin Cam 88” engines as well as 1986-’03 Sportster models. There is no need to remove the gas tank or the rocker covers anymore.
The next step is to increase the displacement of your engine. The S&S 97" Big Bore Top End Kit for 1999-’06 88" engines or the 106" Top End Big Bore Kit for 2007-up 96" engines are an easy and cost effective way to do it. Simply replace the stock pistons and cylinders with the S&S 106" Top End Big Bore Kit. No machining or flywheel rebalancing required. Cams, exhaust, and intake components from steps 1 and 2 will work great with the 106" Big Bore Top End Kit. Dealer installation recommended. Larger fuel injectors, such as the Screamin' Eagle, may be required.
After the displacement of an engine has been increased, and high performance intake, exhaust and cams have been installed, the next step is to make the heads flow better. For this, S&S Cycle offers several options. The most economical route is to have S&S CNC port your stock heads. This can be done on an exchange or rework basis. The other option is to purchase new S&S cylinder heads. Either way, the increased flow of the intake and exhaust ports will allow you to take advantage of the extra displacement by filling it with more air. Dealer installation is recommended and EFI tuning is required. S&S recommends the S&S VFI modules, Harley-Davidson Race Tuner, or Dynojet Power Commander for EFI tuning. Larger fuel injectors, such as the Screamin' Eagle, will be required. For even more horsepower, consider a set of cams with more radical lift and timing such as the Crane 296 cam.
