Some of you that saw my recent post will note that I have purchased a beautiful Honda CB500FA. I took the streets yesterday, joining the Netrider group at the Homebush learner day, before heading out on the group ride. Taking plenty of advice from this forum, I am working on one of my main rider deficiencies, looking behind me. My problem is that whilst I have my OEM mirrors set up to view only a small piece of shoulder each side, I am really struggling to see what is directly behind me (other then the fellow NR Ninja 300 rider who kept getting a bit too close during the ride). I am interested in what others feel is an appropriate amount of lane / vehicle to be seeing behind me, and whether alternative mirrors might help solve my issue. Note that I do not believe I have weirdly wide shoulders.
