I happen to be a tall guy (6'4") so when I got this bike, one of the first things I did was to measure the vertical height of the bars. I found out I was going to need a whopping 6.5" of improvement over stock! So we reached out and got a favorable and friendly response from Rox Speed Fx who said they'd help us out there. These risers look pretty sweet, huh? Rox carries quite a few products beyond risers, including hand guards, so check them out!
