I love the Scythe Mirrors.....P/N 1449.......They DID tend to loosen a bit at "higher" speeds......I got them in the VERY BEST position manually, then glued the threads with a high quality 2-part epoxy glue......problem solved. They now will NEVER move again......really dresses up the scooter, IMO.Who has purchased the Kuryakan Scythe mirrors.Looking for feedback,any problems,hows the vision in them,do they stay tight,I am possibly going to order the Scythe or Scythe II and want to here how they are,thanks.
