My kawasaki ER5 mirrors just gave me a view full of my arms and little else. I debated getting some cheaper versions but went for these Oxford ones instead. I didn’t use the risers because the height of the mirrors was fine as it was, it was just the extra width I needed. I cut the bolts shorter to allow for the risers not being used. They’re very sturdy and stay in place. I’ve now got a great view behind me. The only negative is the caps that cover the bolt heads aren’t the best fit and with the vibration lift up out of the hole for them and as such I’ve already lost one, they are aesthetic although if riding in the rain the water will accumulate but being stainless steel and ally it won’t be an issue.
