Introduction

Back in the early 1950s, there was no catalog full of hop up parts for your motorcycle. Making your bike go faster came from cutting parts off and figuring out how to tune the engine better. It was the latter that George Smith Sr. excelled at. Smith knew how to tune, and how to make a bike fast. S&S Cycle History

Smith had a 1939 61ci knucklehead which became a 74ci and finally an 80ci by swapping out larger wheel, rods, cylinders and pistons. Following the formula, more cubic inches requires more gas to run fast, Smith made up a set of twin carb heads and bolted on a pair of Riley carbs. The result of this labor would become the “Tramp” and the terror of Halfday Drag Strip in suburban Chicago. Smith won enough races to gain recognition and a following of people that wanted him to work on their bikes.

Smith and a good friend and fellow drag racer, Stanley Stankos, were in demand back in 1958 with everyone wanting the pair to make their bikes faster. Soon enough a company was born, S&S (Smith and Stankos) started selling their first part, light-weight aluminum pushrods. They were filling a need in the market with good old American business sense.

Stankos decided he liked his upholstery business more than the motorcycle industry at the end of the first year and Smith was encouraged by his wife Marge Smith (whose maiden name was Smith) to buy Stankos out and continue running it together. Marge was an integral partner in the growth and development of S&S fielding tech calls and handling product sales. Smith continued racing and coming up with new performance parts and in 1966 drew up his first carburetor. He knew the stroker engines he was building needed more fuel and knew that he had to make the carburetor the way he wanted it to be. Working closely with Leo Payne it took about a year and a half, but the first S&S carburetors were born. Refinements of that racing carb brought about the first street carbs—an area S&S would specialize in throughout the growth of the business.

Introduction

The early gas carburetor that was designed for racing, had gained quite a reputation as a street mixer. George added a choke, refined the lower speed mixture circuits and designated the model the “L” or late series carb. Next, stroker flywheels were redesigned, and forged in steel rather than the previous cast iron method. By

1975, S&S had developed the “Super” gas carb that became a legend to v-twin racers. Later, a new body casting designated the “B”, was added and the name “Super B” became commonplace to the growing number of enthusiastic S&S customers.

In 1975, because of S&S and George Smith’s expertise in with long stroke engines, S&S was contacted by Harley-Davidson® and hired to build two 80ci prototype shovelhead engines. The motors were constructed using S&S components and shipped off to Harley-Davidson. The two twins were tested and used in the development program that gave us the 80ci factory motor, introduced in 1978-79.

George Smith passed away, suddenly in 1980. Marge continued on running the company with George Smith Jr, Ken Smith and Sam Scaletta assuming many roles in growing the business. The Super D race carburetor came to life in 1983 and has been in production ever since. Later in the 1980s the H-D Evolution engine was introduced and by 1985 S&S had a full line of stroker kits available for these engines. Proven Performance was growing again.

In October of 1990 George Smith Jr. saw his projects the Super E and G carbs introduced and the market went wild. At one point there was a waiting list of over 10,000 wanting the new performance carbs. Sadly, Marge Smith passed away in 1992 and the second-generation Smith family members took

over running the company. In 1994 that team introduced complete long block engine assemblies that required only a gearcover, rocker boxes, tappets and tappet guides to be complete. By 1997 they had developed the rest of the components and complete S&S engines

were available! These engines, in conjunction with the incredible demand for Harleys at a time when production of new bikes was well under 100,000 units per year, brought S&S out of the shadows of racing and into the spotlight. Through the late 1990s and well into the 2000s, companies like Big Dog, American IronHorse, Confederate, BMC Choppers, Titan and countless others started building production customs using S&S Engines. The 96ci, 107ci and 113ci engines were the hot ticket for anyone that wanted more than a stock Harley could offer.

Introduction

In the time period surrounding this activity, S&S was still racing—at the drag strip and on the salt in Bonneville. 1995 saw George Smith’s Hubba Hubba Team and Andy Gotsis going 200.31mph on their top fuel bike—the first Harley to break 200mph in the ¼ mile. Dan Kinsey piloted the salt Tramp III, a hybrid big twin, to 226.148mph. 2002 saw George Smith and S&S team up with George Bryce to create G2 Motorsports and head into the NHRA with a 160ci 60-degree v-twin that shakes up the Japanese manufacturers hold on Pro Stock Motorcycle. Additional records are set in 2007 at the Maxton Mile where Jeff Bailey and Michael Scaletta show S&S dominance in a number of classes.

S&S celebrated the 45th Anniversary with the third generation of family at the helm. Brett Smith, Tom Smith and Michael Scaletta brought the 145ci engine to market in a special nationwide tour featuring custom builders Arlen and Cory Ness, Pat Matter, Roger Bourget and Bill Rucker of American Ironhorse to showcase the monster engine. A year later S&S came back with the 124ci Tour featuring Rob Schopf, Kim Suter, Wink Eller, Jim Nasi and Kendall Johnson. Following that was the S&S Shovelhead Tour featuring Mike Rouse, Chica, Indian Larry Legacy, Big Bear Choppers and Jesse Rooke. These tours were building up to something, saying something about S&S’ place in the industry.

Introduction

That build up was for the S&S 50th Anniversary celebration. A plan was devised to hold the “World’s Biggest Build-Off” and invite 50 builders from around the world to use one of 50 commemorative anniversary engines to build 50 bikes and compete for $50,000 from S&S. A grand scale plan, but hopefully, a shot in the arm of the custom bike industry—an injection of excitement, camaraderie and history being made all at once. A group of S&S employees, led by President Brett Smith, sat down with a list of a few hundred custom builders and narrowed the list down to 50. It was a long, painful task, but when it was done, the group felt there was diversity and a fair representation of the entire globe. Builders were selected from Japan, New Zealand, Australia, Germany, France, Italy, United Kingdom, Holland, Sweden, Canada, Belgium and the United States. It was truly a global event.

It was an event for the history books—never before has the motorcycle industry seen a gathering like this. 50 of the world’s best builders coming together to share in the spirit of George Smith’s dream, celebrating the custom industry and giving people something to talk about for another 50 years.

S&S Cycle Emissions Lab

Commitment to the Powersports Industry is a statement a lot of companies throw around, but don’t necessarily deliver on. S&S Cycle has been living up to our commitment by addressing the need for emissions compliancy for more than 35 years. After working with outside labs for a number of years, S&S made an investment in the Powersports Industry by launching our own Emissions Lab in 2007, allowing us to test, validate and certify components for our dealers, our partners, and even our competitors. The S&S Emissions Lab is the industry leader in motorcycle emissions testing and consulting services. As a recognized testing facility by the U.S. EPA, California ARB (CARB), and Idiada in Spain, S&S is able to perform all of the testing necessary to show products are in compliance with EPA emission regulations, obtain a CARB EO, or obtain an EU Homologation. Not only does S&S perform emissions testing but we also have the expertise and experience to guide companies through the complete regulatory process to ensure their product meets the Federal emissions requirements, obtain a CARB EO on it, or an EU Homologation.

When we say we are committed to the PowerSports Industry, our actions prove it.

The M8 engine is a powerhouse, but a low idle combined with a plugged up exhaust conspire to mute the true sounds of freedom that this machine was designed to emit Not to worry, S&S have created the GNX slip-ons with one thing in mind and that’s belting out the flag waving, eagle flying song of the American v-twin Combining a 4 5" shell with a tuned baffle and race inspired tip, the GNX lets the sound and power flow out of the M8 Wait, you only want one eagle and a few flags? Not a problem, they include a removable dB reducer that lets you tune the sound to suit your version of the American dream

Fitment: For 2017–2024 M8 Touring Models Features & Benefits: • 4 5” slip-on with premium fit, finish, sound, and power! • Show quality chrome or Guardian Black • Guardian Black is exact match to OEM header • New, unique louvered baffle delivers a rowdier tone • Removable dB reducer • Clears up to 13 5” shock lengths
