Is anyone using these? They make sprockets for the Tecate. You can get them in anodized red, or blue. Check out the link: https://www.vortexracing.com/
Did not see a link for a tecate ... Several for kx250 with 520 chain ... Did u call them and verify this ? I wouldnt mind one ...
They are labeled KXF250 Tecate 84-85 for the first gens. I was told that they are for the Tecate 3s and not the 4s.
THey have rear sprockets, but no front ones. I'd imagine a KX250 sprocket might be the same...
