Hey guys, I have a question about rims. I'm looking for used replacement rims for my 97 KX125. Some of the ones I've found don't look like my stock rims, but are rounded from bead-to-bead instead of the squared-at-the-bead type. What's the story on these round rims? Are they OK for racing? Any advantages or disadvantages with these rims? Thanks, KXBuffalo
