I have tried a number of different bends, all of which had their benefits over the stock Icon bars.
Like Xtyling, I tried Renthal ultra-low, as well as their medium superbike bar.
I also tried Domino 5.5inch trials bars, which were a great bend, and much like the FT bars (cost £27) (and with a flyscreen similar to the Dart, greatly improved touring comfort)
Finally, I ended up with Chrome Triumph T120 export bars which, for me are just fantastic (I love the '70's US Ascott dirt-track look)
All were 22mm dia, so didn't require new bar mounts
