aaaaaaand Welcome to the DMF
I have SpeedyMoto 20mm risers on mine (S2R 800), no problems with cables, wires or hoses.
From studying how the Rizoma rise and sweep will affect things - the added sweep will probably not be a problem. The added rise just might be a problem, but to me it seems like it would only be the fast idler and maybe, maybe the throttle cable. Both of which can be rerouted.
If you do the risers PLUS the Rizoma bars I'm not sure you'll need to adjust the steering stops because the bars will be a lot higher.
WARNING: this is all just thoughts on the matter. I haven't tested it yet.
