As my right knee is starting to give me more problems, looking to move onto a trike. Considering a Goldwing, been riding 2 wheel Harley's most of the time. Need more comfort for co-pilot and driver. Looking for guidance on things to check for on a used bike, I.E. if it shows this or that don't buy unless you want to pay for major repairs later. What potential issues i need to look for?? What options you should have on the bike?? Already decided on the trike converisions I am considering. Looking for a little help, Thanks.
