I purchased a handlebar adapter kit from MurphsKits last year, (I allows use of standard motorcycle handlebars on the classic Concours). My bone doctor says I have to move to a fully upright seating position; so it is this or get a new motorcycle. Being cheap I have opted for the handlebar and seat revision on my Concours. I am ready to start the project, but some family members think I am being stupid doing this and have made me a bit nervous about changing the rider geometry of the bike. Any of you have experience with this type of revision?
