S&S Cycle Sadly Announces the Passing of Warner Riley

VIOLA, WI – June 17, 2025 – (Motor Sports NewsWire) –  S&S Cycle is saddened to share information about the passing of Warner Riley. Warner was an integral part of the S&S Cycle history, and we turned to Ken Smith, George Smith Jr. and Sam Scaletta for a brief look at the many contributions Warner brought us.   

Warner Riley – The Complete Package

Warner Riley’s relationship with S&S Cycle began back in the mid-1960s, first as a customer and then as a friend.

Early on, he had purchased some parts from S&S to build a larger displacement Sportster he had that he wished to make more competitive as he was doing some weekend racing at local drag strips around Chicago.  During construction of the engine, he ran into a problem when fitting the intake manifold to his cylinder heads.  Thinking there was a problem with the machining, he called S&S Cycle owner George Smith.  After talking for a while explaining what he encountered, Warner asked if he could bring his engine so George could look at everything at his home in Blue Island, Illinois.  Since Warner lived on the North side of Chicago, it seemed like the best solution.  After inspection, George determined that the problem was not in the machining of the manifold, but in the way the aftermarket big bore cylinders Warner was using were made. Warner, a graduate mechanical engineer, immediately understood after the problem was diagnosed.

The two conversed for quite a while picking each other’s brain, talking about Harley performance, racing, and Warner thought it would be interesting for George to attend a local race and see for himself what was going on at the track.  At the time, George was working on a new project–a high-performance carburetor for Harleys that was his life-long dream–and some trips to the racetrack seemed like a great idea.

It wasn’t long before a friendship evolved between the two.  Warner’s love for competition and going fast and George’s suggestion soon lead to racing at the “great white dyno,” the Bonneville Salt Flats.  It turned out to be the perfect venue for S&S Cycle to test the durability of its products and for Warner to satisfy his “need for speed.”  Quickly George saw the complete package in Warner. He was a smart, college trained engineer, with a good knowledge of the motorcycle industry, Harley-Davidsons, racing, and was articulate so he could put his thoughts and actions into words.

During the first few years of racing at Bonneville, the pair established themselves by setting record after record, at least 16 total at one time, with the highlight being Warner’s entry into the coveted motorcycle 200mph club.  Along the way, they both were part of the Harley-Davidson team that sponsored the Denis Manning motorcycle streamliner in 1970 that set the motorcycle land speed record, which still stands, with Warner building and supplying the engines and George Smith supplying his new carburetor and doing the tuning.

Warner became news for the motorcycle publications, and because of his ability to convey a message, he began writing a monthly magazine column.  His knowledge about the magazine industry and association with the publications enabled S&S Cycle to more efficiently advertise on a broader scale, making the public more aware of the company, and that greatly helped sales of S&S products.

Meanwhile, Warner’s relationship with the Harley-Davidson factory and racing department blossomed beyond his primary interest, going fast.  His training as a mechanical engineer and ability as a motorcycle rider put him in a unique position to test and evaluate Harley handling characteristics, performance, and features and serve as an expert witness in many court cases.  His experience in court also helped S&S avoid legal issues during product development.

On another side, our friend Warner was a guy with other interests. When S&S cycle relocated to Viola, WI, he would make the drive to visit and combine business with pleasure, often bringing a dirt bike or new gun to shoot. On one trip, a Saturday was planned where any of the S&S shop employees who had a favorite firearm could bring it to the farm and shoot at a junk foreign motorcycle he donated. You guess the brand.

With little left to prove, he retired from active Bonneville racing for S&S Cycle shortly after George Smith Sr. passed away in 1980.  His friendship with the business and family did not end there, and nor did his enthusiasm for the sport. He would often attend Bonneville Speed Week to watch and talk with old friends.  He became a friend of George Smith Jr., who had taken over as the company President and was responsible for research and product development. Much like his father, George Jr. ventured into Bonneville racing and on occasion, Warner would help him when he had a problem.

When George senior was inducted into the Motorcycle Hall of Fame in Sturgis in 1994, Warner said he had to be there to say a few words.

All that can be said is, what a guy!  Warner was the complete package, a great friend, and will be sorely missed.

Rest in peace, friend.
