This piston is available in different clearances to fit your bore perfectly.It has a wider ring end gap than a Wiseco, but in my instance this was a good thing because it allowed me to run pump gas without worrying about damaging my engine, not to mention much easier to start.

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.
- 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.
Well as always it's a perfect fit this is the 3ed piston I order and can only say I'm very happy with the coast and support I get from you guys thanks
Great part just get it you will love it
Good piston. Gave me same power as other brand name pistons. Great price. After a good bit of riding I took the piston off due to a lack of power and found a big chunk missing from it but oh well will buy again
Great piston for the price. Developed the same power I get from use of other pistons I have tried. Easy to install. One thing is I took the piston off due to a lack of power and it has this big chunk broken off. Never dropped the piston so got not clue on that either way im buying another one
Completely satisfied with the purchase and operation of the piston.
I use PRO-X Pistons for the Quality and Durability . Motosport sells it in a package with gaskets and a rod bearing everything you need to get back on the track. Braaaap
Motosport has always been my go to place for all the parts I need! They have the best prices and quick shipping, so I can get back to riding my ATV faster and safe money! I am a person who likes to trade and work on projects, and Motosport always has the parts I need.
We always rely on ProX Top End Kits.... Excellent Pistons.....
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.
