Just picked up my mounted MT-21 rear rim and tire setup for my 04'XR650L. My shop told me they installed a bead lock. I never noticed it didn't have even one!! Good thing as I have sheared my stems a few times on different machines. My Zilla had to have bead lock rims as it sheared them a few times alone. My CR has three, and my 600R has one. Did XR600's come with factory bead locks? I was told 650L's did not.
