Pro taper SE cr high or Renthal cr high in 7/8" are a good choice.
I have seen the ATV high bars recommended in many forums (strom, KLR, DR-Z) and I was using those on my KLR and DR-Z, but found I was having discomfort. Also, those bends caused me to keep my elbows down in the dirt. The CR bend bars are much closer to perpendicular. Looking at my other bikes, I would say they are slightly straighter than "splitting the difference" between the stock 'strom bar and perpendicular, if you follow. I may try a spare set of the ATV bars on my wee this weekend, as I only ride roads with it, but if that doesn't cut it, I will be putting CR bend bars on it as well.
The bar manufacturers give measurements on their websites so you can get a good idea before you order. The Pro Taper is available on amazon for $57.
