The mirrors arrived in good time, were well packaged and the instructions (for a very simple process) were easy to follow. These items are not cheap, but they are clearly really well designed and engineered. If I didn’t know better, I would have guessed that they were OEM optional extras. Better still they are excellent mirrors - far better placed for a clear veiw to the rear, rock solid and wider view. An added bonus is that they have reduced the vibrations from the boxer engine that used to be troublesome. Only issue is that the blanking plugs provided are clealy not for the model of my bike. Admittedly, the R1300RS is a new model but I would have expected Evotech to have caught up by now - offer blanking plates for this model as part of the product, or even as a separate product. On an unrelated point, the tech support responded to an email enquiry on the same day. I'm totally delighted with the service and thhe product.
