The current crop of 4T's have these little slipper pistons. They don't have the life of the pistons of old. I put about 40k miles on my xr600 all on the same piston. Probably 1000 hours or more. I did have to re ring it, but it still measured within limits and it ran for several more years.I hope that my Beta's piston makes it to 200 hours. That is a lot for a slipper type piston design. Run a piston too long and they have a way of breaking a chunk off and doing catastrophic damage.
