New rims needed?

Hi all,

As some of you have read, I am going to do a bit of racing on my WR in the future. I was wondering if the stock rims will hold up ok to the punishing terrain? Should I be getting some Excel rims or the likes?

Thanks all!

just run 90/100-21 front tyre, and correct pressures and worry about new rims if/when something happens. then get SM Pro Platniums, heaps cheaper then excels and testing reckons they 25% stronger than the A60's
