Unless you want to really really race the sport class.. upgrade to a 400ex, or a 450..

Otherwise you're going to be spending a lot of hard earned cash on a quad that will "keep up" with an 400ex that costs half the price. I know people hate seeing that.. but most people that have built up their 300ex's would agree.

Honestly.. for the price it would probably be cheaper to but a decked out 400ex used.. rip out the motor. Sell it. Then buy, and instert a 250f motor.

I concur. I want to put a CRF 250R motor in my 300ex.

The frame isn't strong enough I believe. Just a waste of money and a lot of mods would have to be done to get it in there. Hooking up the radiator, mounts, lining the sprockets and chain up intake lining up ect ect. Plus gusseting. Not worth it IMO.
