The OEM's round Mirror has a small mirror surface area and a narrow viewing angle, making it difficult to see behind. Replaced the Shark mirror that was on the previous car.
Interference with the Right Side Throttle Cable was my biggest concern, but I had no problem. [Color] Clear, so it can be installed on the CT125.
Ease of viewing is a given. The two curvature/area combinations provide very good rearward visibility, and the RaySave mirrors reduce glare even with modern LED headlights.
Another side effect is that vibration around the handlebar has been reduced, probably due to the considerable change in Mirror weight.
