There are several stabilizing braces that have been out for a while (e.g. bagger brace, and the Progressive touring bike bagger brace), most well reviewed and discussed on this site. An outfit called Scorpion Motorcycle Components set up at Sturgis this year and was selling what they call a "smooth rider." I am looking for reviews and opinions on this brace for a 2008 Road King Classic. I am trying to understand whether it might be preferable to the Progressive stabilizer brace. I WOULD BE MOST GRATEFUL FOR AND APPRECIATIVE OF YOUR VIEWS OPINIONS, EXPERIENCES AND RECOMMENDATIONS PLEASE. Here is their web site: Stabilizers for Harley Davidson Touring Models - Scorpion Motorcycle Components - Smooth Rider. The site states: "Stop the Wobble Stop the wobble with our Smooth Rider. Our engineers designed a stabilizer that does not bind the transmission to the frame. This allows your motor and transmission mounts to work as designed. Our design uses a rail and guide concept that provides for extremely tight clearance tolerances which maintains transmission and frame alignment. This type of design has proven to virtually eliminate the wobble. Specifics: * Fits 1993 thru 2008 Harley Davidson Touring Models * High Performance Urethane Vibration Inhibitor * Simplest Installation on the Market * Does Not Impact Ground Clearance and air flow across the oil pan * CNC Machined 6061-T6 Aluminum" This link explains their concept: Scorpion Motorcycle Components - Smooth Rider - Basics "Our engineers were able to create a rail and guide attachment that did not permanently bind the engine/transmission to the frame. A high performance urethane inhibitor was developed and inserted in the guide. The rail would fit in the urethane inhibitor with minimum clearance on both sides. Once the conditions were starting to develop that would result in the harmonic effects, the rail would come into contact with the urethane inhibitor, bring the engine/transmission into alignment with the frame, and stop the conditions before the wobble could start. After the alignment action was complete the rail would return to its normal resting position. Simplest Installation on the Market! Smooth Rider without a doubt is the easiest stabilizer to install. A total of three components and five bolts make up the stabilizer. The Alignment Bar mounts to top of the factory cross member (dog bone). The Guide mounts to the Alignment Bar and the Rail mounts to the transmission. The high performance urethane vibration inhibitor located in the guide does all the work of stopping the conditions that create the wobble. Smooth Rider does not affect ground clearance or air flow across the oil pan."
