Spending £300 on mirrors is not something I intended doing, in fact I reviewed many different brands of mirrors which were far less expensive. That said, I have bought cheaper mirrors in the past for other bikes, and I was generally disappointed with the quality and the distorted view. Anyway, I took the plunge and purchased the Evotech bar end mirrors with brake and clutch protectors for my Ducati Diavel V4. Cost aside, they are great, good quality construction, sturdy and stable at speed, and the image is crystal clear. Great mirrors - you get what you pay for!!
