This video is the conclusion of the S&S Old School Shovelhead buidoff.
Personally, being into custom choppers for many many years, I think the S&S motorcycle engine is without a doubt, the best the twin motorcycle engine available! I’ve seen many custom-built choppers where one-of-a-kind rolling art work creations look magnificent but for some unknown reason the builder decided to put in some imported, dubious quality the twin engine.
S&S Motorcycle
I believe that both Big Dog Motorcycles and American Ironhorse Motorcycles, two of the top factory customized motorcycle builders, went with SNS engines in their motorcycles, was because of the engines quality and dependability and lastly the fact that they are manufactured right here in the U.S.A.!
S&S Cycle develops performance replacement engines for v-twin motorcycles, most of which are replacement engines for Harley-Davidson models and are manufactured in the United States. In addition, S&S Cycle developed their own proprietary pushrod v-twin engine, dubbed the X-Wedge that features a 56° cylinder angle instead of the 45° angle used in Harley-Davidson v-twin engines, and which was developed with the custom motorcycle builder (OEM) in mind. The X-Wedge is the basis for the engine from a number of high end motorcycle manufacturers such as Arch Motorcycle and Confederate Motorcycle. The X-Wedge recently found a different kind of application, having been chosen to be the power plant utilized by Morgan Motor company, based out of the United Kingdom, for their development of the Morgan 3 Wheeler cycle car.
S&S 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. S&S is the only motorcycle company in the world to manufacture Knucklehead, Shovelhead, Panhead, Evolution-style engines and Twin-cam style engines. S&S manufactures the largest (143 cu. in.) engine to fit a stock Harley-Davidson frame.
