I have a 2007 1600 Vulcan classic. When I purchased the bike it came with a cobra backrest for the passenger. My wife said that the backrest would make her back itch when we rode, even short trips. So I converted the backrest into a quick-attach mount. This however did not seem to help. So I was wondering if anyone has had similar issues and if so has anyone been able to come up with a solution? Any help would be great. Thank you.
