I bought a 500 EXC this spring, and at 6' 2" I found the bars to be too low for off road riding. I got a set of Trail Tech bar risers from Gnarly Parts in BC. They're anodized orange so they look sharp on the bike. The rise is about 1 1/2" which is about as much as I could get with a new set of bars, and cost $100. Not much of a cost savings until you consider that I didn't have to do much work or buy new grips. I would definitely recommend them if you're a taller rider.
