The Rizoma bars are just over two inches taller than stock bars. The added sweep is somewhere in the one inch area. Both measurements will be a little different depending on how you rotate the bars.
Usually, your stock lines and wires will be long enough with the Rizoma OR the Genmars, but even then some rerouting may be required. Combining the two will probably require some new longer items.
My FHE is with the SpeedyMoto 20mm risers - the only issue was a tight fast idle cable, but didn't have to reroute.
The Rizoma bars might give you a much more comfortable wrist (sweep angle) and be tall enough?
I'm sure PJsParts will know more about the Rizoma and if you can install without issues. Or, of course, some of the guys here
