I’ve had a Griffin sidecar fitted to my Touring. Looks, feels and rides great but have low speed head wobble on occasions. Advice received so far is to tighten headstock bearings and fit a linear damper. Has anyone here fitted a steering damper and, if so, how did they go about procuring what’s needed, ie a bolt on clamp kit and damper? Wondering if available as stock or do I need to go custom somehow?
