Best upgrade for a Brute 650i

I'm getting the itch to start some upgrades on my Brute 650i.

What would you guys say is the best upgrade for the money?

I'm seriously thinking about tires and wheels as the first upgrade. How tall of a tire will the 650i handle without rubbing or being to stressful on the stock belts and stuff? I'm thinking of going with 26 or 27 inch Mudlite XL's.

Thanks

Best upgrade you can do that bike is a power mudule.Highlifter sells them for about $100 and they are plug in and play,you can get as high as 500 for a VDI...

Depending on your type of terrain you will be rising on I would say 26in tires.WOnt have to mess with you clutch and still keep your power

I would have to say tires and rims, and I would go with the 26"

Well, I couldn't pass up the deal and ended up going with 27" ITP Mudlite XTR's, on ITP T-7 wheels.

Man, they look awesome, can't wait to hit the trail.

These tires were shipped with 7 psi in them. Is that too much? I backed them down to 5 psi and I'll see how they do.
