These are great pistons. These are the only pistons we run now. On our practice/trail bike I let my son go to 90 hours on this piston and decided to replace it. I probably could of put another set of rings on it and continued to run it but we were doing full motor rebuild and didn't want to cut corners.

Hot rods makes a good complete crank, this is the first time using Hot rods and I'm very happy with the quality of the crank.

I grabbed this Pro X piston kit for my top-end refresh and it worked out great. Everything came right in the box piston, rings, wrist pin, and circlips and the tolerances were spot-on. The fit and finish are top-tier, dropping right into the cylinder with smooth action and great compression once sealed up. Solid quality and zero issues definitely a go-to kit if you're rebuilding on a budget without sacrificing reliability.
