No, Never, razor pro bars are wider than the ultra it just wouldn't fit
the only diferrence is that the lo has lower and closer bars, but has a new peice of metal so its a lot harder to snap, about 40 more expensive
razor ultra pro is way better! but there is a razor ultra pro lo.... that is even better then the both. u should get that one for sure and if u have a youtube subscribe to GNITGHIF
I have a strom and the bars are 21 high by 18 wide, they are goood bars but are pretty plain
razor ultra pro's r better cos they r all one peice
