These are a must to increase your rear view. I saw a guy on a buddy 125 who showed them to me on his scoot and knew that was the answer to my problem. After ordering the wrong ones I finally got the 10mm correct ones and it's like night and day. I feel safer riding changing lanes, viewing what's up behind me. Cheap upgrade for sure. Might have gone with new mirrors but on the movie they're color matched to the scoot. Anyone who sees mostly shoulders/arms in your RV mirrors these are a must, seriously your life just might depend on them. They extend out 3in and up 1.5in.
