FAQs

Did Harley ever use S&S motors? ›

The 145” Tribute Evolution style Big Twin engine celebrating 45 years of S&S being in business and 100 years for Harley-Davidson is used in a special series of bikes built and offered by five selected custom builders.

The company was founded in 1958 by George J. Smith and Stanley Stankos in Blue Island, Illinois. The company started by selling high performance pushrods for Harley-Davidson motorcycles, and today they still make parts for a variety of V-Twin bikes. The company's current president is Paul Skarie.

S&S stands for George Smith & Stanley Stankos, the founders of the company in 1958. Based out of Wisconsin, S&S Cycle has become one of the most trusted names in V-twin performance engines.

S&S are an extremely established engine manufacturer with endless engines and engine products on the market. We have given you a snapshot of a few of the varying engines they offer, including their features and benefits. However, every S&S engine is undoubtedly reliable and able to keep you safe on the roads.

Among its engines, the best Davidson engine is the Milwaukee. Since the founding of Harley-Davidson motorcycles to date, the company's most reliable and advanced engine is the Milwaukee Eight. The engine was introduced in 2016 and comes in two versions, the 114 and 117 cubic inches of displacement.

113" Super Sidewinder™ for Evolution ® Models

Shorter than stock by about . 050" it will easily fit into any standard height Evolution ® frame, but the difference will be anything but stan-dard! With over 110 HP the 113" is a real powerhouse and is loaded with time-proven, high-performance features.

It's big, 143 cubic inches. Nuff said. At double the HP of a stock motor the power of the 143 requires technical expertise for the installation and tuning along with an experienced rider. This is an ultra performance/race engine.

Origins. One of the first V-twin engines was built by Gottlieb Daimler in 1889. It was used as a stationary engine, for boats and in the Daimler Stahlradwagen ("steel-wheeled car"), Daimler's second car. The engine was also manufactured under licence in France by Panhard et Levassor.

Since then, the FL prefix indicates that the traditional 16-inch front wheel and big fenders are used on ″Dresser″ Touring series or the traditional styling ″Heritage″ variants of the Softail series, while FX is used on sportier models or the chopper-like Softails with rather thin front wheels.

Harley-Davidson engines are a line of engines manufactured since 1903 in Milwaukee, Wisconsin by the Harley-Davidson company for use in its motorcycles. Harley-Davidson engines are now made at Harley-Davidson Motor Company's Pilgrim Road Powertrain Operations facility in Menomonee Falls, Wisconsin.

Does S&S make a Panhead engine? ›

The engine is just as tasty. It's a 93 ci panhead motor from S&S Cycle, hooked up to an S&S Super E carb, and aftermarket exhaust headers with MB Cycles mufflers. The ignition, coils and oil pump are from S&S too, while the charging system and regulator are Accel parts.

Our sport models today serve as a modern adaptation of the Harley-Davdison® Sportster® models throughout our history. These come loaded with technology like Ride Modes, ABS, TFT and more to help bolster confidence in both new and experienced riders.

The Evolution Big Twin saw a fifteen-year run in Harley-Davidson's Dyna, Softail, FXR, and Touring frames, although a limited number of Evolutions were used in the 2000 model year CVO FXR4, and 1999 FXR2 and FXR3 models.

S&S complete engines for Sportster and Buell chassis are available in 91" and 100" displacements.
