Interesting comments martin G10, I have the same ones as those shown in the Heritage model photograph. I must admit I prefer them to the stubbier ones shown in the other picture. However, they are just not fit for purpose. I reckon that the offside rear indicator on my Spitfire 6 vibrates about +/- 25mm at around 3000 rpm so no wonder it doesn’t last long. I was hoping CCM were developing a new indicator to solve the issue but, from their last correspondence, it seems not.
