Have owned my 400f for many years now, it's original but not concours. Now that I'm retired I prefer riding it when wife & weather permits!! Whilst I like originality I'm also a realist, and with todays traffic, mirror use is of prime importance, and the standard fare leaves a lot to be desired. Many years ago I blagged a ride on a pal's bike that had Stadium bar-end mirrors fitted, and I thought at the time they were superb. It now transpires that these are still available under the Halcyon name. Not cheap, but British made from Stainless steel. Just wondering if anybody has tried these, and wondering how out of place they would look on a 70's 400f?
