Wunderlich bars
I had black HB bars on a previous bike (Tiger) and the paint was very fragile.
I have fitted Wunderlich bars to my GS and unwillingly tested them this week - a Jeep Cherokee body checked me. I didn't come off but have his blue paint and rubber on the bars, rocker cover etc. All came off with T-Cut and there isn't even a scratch on the Wunderlich bars.
A rare occasion where the bike came off best!
