Im doing a rebuild on my bike making it better for woods riding. I have a 2004 WR450F and i was just wondering if a weighted flywheel is even worth it if i dont race. If so, which kind should i get and how heavy should it be??? Any info would be helpful, thanks:thumbsup:

In my opinion, the WR's come with a heavy enough flywheel. Are you having issues with trying to get it to hook-up? Traction on rocks? If your not racing, I say skip it. Heck, I race mine and I find no need for it either. Your results may vary. Maniac

I had a 99 YZ400F and lived in Chicago, I got a flywheel weight cause I was always stalling the bike and had zero traction in the slimy clay.. Moved back to California and took the weight off after the first ride.. I couldn't climb a hill to save my life!!

So the question is why are you considering one?

I have no problems with traction or riding, i just really had no idea what they were for and how they worked. I know how a fly wheel works, but i just never know what a weighted one did... now i dont want one haha

The WR's come stock with more weight than a YZ does, so they are "weighted" from the factory.

I had a CR250 for a while that spun the wheel so fast and was hard to control in the slop so I put a 14oz. on it and it calmed it down nicely. NO real need for the WR unless you are having issues with keeping the wheel from spinning in slop or stalling at low speed.
