I got the '758' bars, in Silver. They call them 'Road Bike Ultra Low'. I wouldn't say there's any more rise than the standard bars, they're a little wider, and quite a bit less raked back at the ends. Feels a slightly more 'aggressive' riding position.
I haven't got the master cylinder on yet but with a 'dry run' it seems like the length of the HEL lines will be fine, especially if I route them to the right of the horn bracket etc (2 lines, not 3).
I'm waiting on getting the nerve to attempt tapping the bars in order to use the stock bar ends.... And drilling the holes for the switchgear in the right places. Gulp! The tap has arrived (~£9.50 Amazon), but Brave Pill, and clear head, needed!
