Wheels m/c


I've been really banging up my stock wheels on my XR 650r. I ride/race in Imperial valley and baja. Last month I put a big ding in the front rim and it broke when my friend tried to fix it on a vise. This happend after a ZR promotions race in Mexicali. The rim was replaced and I was off to the next race which was last weekend. After the race I noticed another big ding in the new front rim. This wasn't as big as the first one but very noticable.
I went prerunning in San Felipe the last 2 days and now I have another one in the front rim and 2 in the rear rim. This terrain is very rough with lots of submerged rocks,sections of crushed rocks and a bunch of hardcore stuff. I know I hit some stuff so hard it causes your hands to come off the bars and almost loose it. I know if I slowed down and was more carefull that would be the obvious answer but what about on race day ?
What can I do or what wheels are recommended for this type of riding/racing for this hard terrain ?
Thanks for the support and help....Paul

If you are running aluminum rim ,switch to steel little heavier but stronger also bigger tire if possible and more air pressure jim g

I'm running a Dunlop desert D739 A/T in the rear and a Pirelli MT 18 in the front. I run 15 psi in both tires.

I'm not familiar with the Pirelli MT18, heck I'm still running a Dunlop K139. The K139 was the tire of choice for desert racing before Dunlop quit making it, I don't know what the replacement is. The side walls were so hard you could run it flat into your next pit. Just put a couple of tie wraps on it. We always ran 20+ lbs of air especially on the rocky courses. Harder tires (more air) don't handle as well in the sand but it's a trade off for the rocks.
