In terms of comfort I am still contemplating whether I should get the Speedymoto risers w/ OEM handlebar or a Brutale handle bar to replace the OEM one, which is damaged from a crash. Leaning towards the Brutale bar.
I switched to Rizoma bars on my S4R, similar contour to the Brutale -- more pullback/sweep which makes a huge difference over the OEM. Search this forum for Brutale, I think you'll find another thread with a lot of discussion about bars.
