Tiny little engine.
I wonder how long a piston kit would last trailriding?
My bike has 65 hrs on it now, all MX. I put a piston in at 30 and 60hrs both times they were still fine, cylinder still looks new. I would say 50 hrs would be fine if your trail riding, my friend with the 167 went 80 hrs on the last piston.
