I'm taking off next weekend, so I thought I try a set of bar risers I had picked up before I left. I have an S4RS with an Ohlins front end. I mounted the bars and risers but the front brake line is too short. It would fit, but would be stretched to the limit. There is no room to make any slack in the lines. The maker claims the risers fit without mods, maybe on the S4R, but not the Ohlins.
