No, the part numbers are different. You can go out to Yamaha's web site and look up numbers... here you go.

There's a company called AC Racing that makes subframes but I don't see WR450 on their Yamaha list. You may want to check with them to see if they know someone who does offer one; worse case, they could say no.

If the weld broke get a new welder.

The trouble with welding Aluminum is you end up with a heat effected zone of about 1" on either side of the weld where the material strength is significantly reduced. The subframe should be repairable if you can determine the actual material (probable 6061 but could also be 6005, 6063, 7005,7075 + many others), find a good welder that is experienced in welding different alu,inum alloys and then find someone to reheat treat the frame. For the frame to live, it MUST be re heat treated.

the reason the weld broke is becausa a weld fixex that place. the weld will ALMOST NEVER break it is right next to the weld that breaks try welding a peice of steel along it the whole lenght and that will probaly hold

Often the different part numbers may simply be due to a different color or finish, so don't let that dissuade you.

Also, there are plenty of subframes on eBay that sell for much less than $150.

Snag a YZ subframe off eBay and have someone with a welder add or subtract brackets so it will work. Honestly, how different can they be? Same attachment points for the seat, fender and silencer as a YZ, right? ? Do whatever it takes to go riding!
