"Now that our dampened direct drive sprocket has hit the internet I should comment to dispell some myths and put out as much fact as I can:
The composite of our bushings were designed and developed by a company that makes many couplings and dampners throughout many industries including the automotive industry and knows all the dynamics of this style bushing in harsh enviroments, this was key to our continued developement of this product. This bushing design and composition is light years ahead of Sturgis models of the 80s.
The design of the compartment they are captured in is not an accident. This style bushing needs to act essentially like a liquid and move in the direction that we want in order to reduce heat build up, if the compartment is too small the material actually has to work too hard, attempting to compress and have no where to go which creates excess heat and will cause material to breakdown, yes. I relate it to a run-flat instance on a tire, the rubber in a tire that is flat ends up working too hard and without air in the tire(air is essentially the heat sink that dissapates heat build-up), the tire overheats and the rubber in the carcass fails.
Currently we only have stock gearing to enable us to have a constant throughout our testing (not yet available to the open market btw, sorry), but have plans on a selection of gear choices primarily driven by input from many at the show, inc. Bert Baker and Bobby Woods. We believe this sprocket should be made available to dealers in a number of gearing choices by a June 1st release date.
We have a # of different durameters of our bushings to accomodate different ranges of HP #s and riding styles. In our testing stages these are water jetted, but the molding company that we are working with will be molding them after all designs are solidified by final analysis of testing. The cost of the bushings (primary wear item) we expect to be $24.95 retail and our goal is achieving a 75,000 mile life span. Regardless, they are an easy change in chassis if wanting to change durameters of bushings or for sevice.
This dampened sprocket system has been in various stages for well over a year now, but we must give the market our best effort in durability and quality. Having all of our patent applications in place we decided to unvail at the dealer show to gain everyone's input so we can give the market what they want in a timely manner. It has proved to me to be quieter and smoother that anything I have experienced on the market today, with quiet starts & smooth operation throughout rpm ranges in a lot of different applications so far in our testing."
