Supersprox 'Super' Stealth Sprockets for Chain Drive Conversions and Performance Bagger Applications 


Designed and made in Europe by Supersprox, this new 'Supersprox Stealth' range Cush Drive for Baggers and Touring is a must have power upgrade for those who are serious about getting their big inch power down onto the pavement, where it belongs.

A new 'must-have' go-to solution for those looking to build resilience into Bagger Racing Tourers too. 


Cush Drive for Performance Baggers and Touring FL Applications



"Supersprox has engineered the Ultimate upgrade," says CEO 'DJ' Maughfling. "One that is specified to handle the power that today's Performance Bagger drivetrains are generating."

Available for '09-'16 and '17-'22 Touring models, these sprockets are CNC machined from high strength, lightweight 7075-T651 heat treated aluminum-zinc alloy (aka Ergal) - used in sprocket applications, the high strength, lightweight material minimizes rotational mass to maximize acceleration.

The all-aluminum construction (aluminum core and hub) with steel teeth is said to provide up to 3 times extended chain and sprocket system life, compared to aluminum sprockets. 

Supersprox has been in the sprocket business since it was founded in 1959 by the father of current CEO DJ Maughfling. Supersprox became well known for its invention of the hybrid sprocket back in 1999. It has steel teeth, for long system life and aluminium core to reduce rotational mass. Over the past 25+ years, this sprocket has been used on the winning motorcycles at the legendary Dakar rally, 19 times. Its race proven material, for sure.


Earlier this year (at Las Vegas for AIMExpo) AMD met up with DJ just as he was completing testing and starting to science-out his sales and marketing strategy for the 'Supersprox Stealth' range. 

Brandishing some freshly machined and finished samples, DJ explained the history and prospects for Supersprox' future in the V-twin market.

"I was in the US during 2023, attending national sales events for our key distributors. I was repeatedly asked about our range of V-twin sprockets. At the time, it was relatively modest and not as well evolved as it now – back then it was a market sector that we just didn't understand.

"What was obvious is that there was increasing demand and a widespread perception that the existing belt drives being offered for V-Twin applications, especially at the heavy-duty power end of the market, simply had not been engineered for the stresses they have to endure.

"Knowing just how robust and well-engineered our sprockets are, knowing the quality of our processes and our materials, it was quickly apparent that we had an opportunity to meet a genuine need."

Asked if the demands that big inch, heavy V-twins placed on sprocket durability came as a surprise, DJ said: "No. Even those of us who have historically specialized in metric and MX sprockets know enough about Big Twins to understand that they do make unique demands on the power transmission cycle, which is why belts have had such a big role to play in the development of Harleys.

"It's not that sprockets can't be made to be strong enough and light enough, it's just that there hasn't been sufficient demand before."

And now there is? "Yes. Where there is a need there is an opportunity and at the top-end of the market, throwing 800 lbs of Bagger around racetracks like COTA, Road America and Laguna Seca has shown that there is a need and they have created the demand for power transmission that gets the job done. Our sprockets are the real deal. Reliable, strong, durable and light."

The 'Supersprox Stealth' is a genuine range though, isn't it? Not simply a single sprocket option, right? "Correct. It is a genuine range with which dealers and performance engineers can reach a widespread market.

 "We are offering four new items for the V-twin market. The most important, in terms of complexity, are our complete replacement cush drive hub and sprockets, to convert 2009-2022 touring models (Baggers). These bikes are pushing out too much power and chain conversion is becoming an essential upgrade.





"Our sprocket and hub are a complete plug and play combination, that allows dealers, racers and riders to tune bikes to much higher limits. The hub is made from 7075-T651 aluminium bar and CNC machined in-house at our western Ukraine factory. The hub comes with a 51T sprocket, installed. We can also offer larger sprockets if the bike will be used for stunting

"We have also made a really cool addition to the flat rear sprockets for Big Twins - FLH/T and XL models. There are generally two sprockets available, the first with 1.99" internal locating hole and the second with a 2.22" internal. We have made a neat insert, that allows the sprocket to be used for both applications. 

This is needed, because the sprockets on the market are not currently interchangeable and it is easy to buy the wrong part by mistake, as they look very similar. We are offering these sprockets as 'Supersprox Stealth' (hybrid) versions and an all-steel sprocket, with the same interchangeable inner. They come in Black, Gold, or Red."

How about for the Pan America? It hasn't sold in great numbers initially, but it is very well regarded in ADV circles and riders who have bought it are loving it. It's even found favor in racing circles – trackers and Super Hooligans especially. In street sales terms it is regarded as a bit of a 'sleeper' whose time will come.


"Yes, and there is clearly a need for some performance parts to fit the Pan America 2011-2025. We are offering a 'Supersprox Stealth' (hybrid) sprocket version and an all-steel sprocket, with the same interchangeable inner - in 19-tooth for the engine and 48 for the rear. Larger and smaller rears are available on request. They come in Black and Silver, and we will add more color options, if there is the demand."

How about turn-key options? There must be great opportunities for complete kits? "Yes, and that might be the most important addition to our range.

"We are making complete packages for dealers and riders, with the addition of transmission sprockets. Honestly, it took me too long to develop the sprockets for the Big Twin Harley models, 5-speed and 6-speed bikes, plus Dyna Glides. However, the finished sprockets have many applications and will fulfil some demand in the market. 

"We have noticed that the former "main producer" in US (PBI) is not offering the same range and Harley transmission sprockets, seem to be missing from their lineup. We can provide reasonably priced transmission sprockets in 4-different offsets - flat type plus 0.250", 0.500" and 0.750" offset. All in 530 chain size, with 23, 24, 25, 26 tooth options."
