Try the Renthal 735, this has the same bend as the standard bar, but is 20mm higher, it is also about 5mm (ish) wider. It is a trials bar so the cross bar is shorter. 20mm is the maximum rise that you can get without changing cables etc. The higher bar will allow hand guards to clear the std screen on full lock and give good clearance above the tank. It also makes riding the bike off road (standing up) much more comfortable.
