Mick, I'm really interested in learning more about your trekking handlebar setup. I'm considering the same for my 750. The stock stem on the 750 is relatively short, but with a longish reach (120mm), so I'm pretty leaned over riding it, and I get some hand pain. I've been thinking of butterfly bars with foam grip like what you have. Could you post some more pictures of your cockpit setup? Curious to know what brake levers/shifters you're using, etc.
Thanks!
