Hey Guy's,I found a CRF450 front wheel. I know the wheel is different.What I need to know is can I put my XR650L wheel bearings in the CRF450 wheel to make it work?

I think that you can forget it.

450X uses a 6904 bearing that is 20mm x 37mm x 9mm

650L uses a 6003 bearing that is 17mm x 35mm x 10mm

You would need to find a bearing that has a 17mm ID and a 37mm OD. Don't think you are going to find it. Not 100% sure if a 10mm wide one would work or if you would need to find a 9mm wide one.

It wouldn't be that much work if you really wanted to do it. There are two options:

-Call a bearing company like Motion Industries and ask them if they have a bearing that matches the required parameters

-If not, have a machinest build you a sleeve to increase the effective ID of your axle

After that you may need to do some work building spacers to center your wheel and a bracket to relocate your caliper, but I'm not certain about that.
