Got mine today. I'll fit them after this weekend's ride. I realized I need new bars. The touratech F650GS Magura bar kit has the bar cut pretty narrow with the grips sticking off the ends to allow the BMW heated grips to work. So in reality my bars are narrow than I thought. I'll pick up some Pro-Tapers next week.
Paul happened to have a 100x43mm top clamp to work with my Touratech/WP fork kit.
