Product Description

Important note: This piston is for a stock sized bore. Please measure your cylinder to check clearance before ordering.

ProX pistons are precision machined on the latest, state of the art CNC equipment. The same low-expansion, low-friction piston alloy is used as is used for all major Japanese and European engine manufacturers. ProX Piston Kits are a first class solution to replace the original piston in your machine.

Most ProX pistons come with a coating. The O.E.M. style tin-coated pistons assist the wear-in process as when you first started the bike. ProX has developed a new skirt coating that not only assists the wear-in process, but also helps reducing friction after the wear-in. The black coating is made from a delicate mix of materials and will increase performance.

  • Bore diameter: 66.35 mm.
  • Cast piston puts engine back to standard specs without boring or replacing cylinder.
  • Interchanges directly with O.E.M. part.
  • Piston kit comes complete with piston, rings, pin and end clips.

Good replacement
I have been told that Pro-X supplies the OEM's. If that is true, then their pistons should be as good as Honda's. Only issue was that I replaced a Pro-X that lost a piston skirt after less than 30 hours. I was told that 2003 CR250's eat piston's though, and that 25-30 hours may be expected.

I just got the pistons into my 125 and it fits great And it's not to hard to put in I did it my self and I'm only 14 so I think that this is a good product and it came to me on Kauai in 2 days.
