Description Item #WCO000P

Wiseco leads the performance aftermarket by producing the highest quality forged pistons in the U.S.A. Wiseco is unique because they forge all of their own pistons in-house, and produce all of their own forge tooling in the U.S.A. This allows Wiseco to control all aspects of their manufacturing process from raw bar to skirt coating on the finished parts.

  • Much stronger than stock. Forged using the highest quality materials available resulting in a piston that provides excellent performance and durability.
  • Tight tolerances for quiet running. Featuring a race-ready dome finish with smooth edges for improved combustion flow.
  • More hours with peak performance between piston changes. The rings, wrist pin, and circlips are manufactured by Wiseco under their strict quality standards to make sure every piston kit fits correctly, ensuring top performance and long-lasting durability are achieved.
  • The Wiseco Pro-Lite Piston includes: piston, ring(s), wrist pin, and circlips.
  • Note: Oversize piston requires cylinder sleeving and top end bearing not included in kit.

Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance.

They guys at Motorsport provided the best customer service in the world. I will always going to shop from their website. This kind of customer service is what we need in America. The owner of this company is very smart how he/she runs this business. Keep up a good job guys.

Now let me move on to the piston. I love the quality of the product. It looks really well built but I have not taken my bike for a ride yet. It is too hot here in California, where we can ride. In 2 months or so then I can tell if it holds up to it name.

Feel the power

Put a fresh top end on my sons kx100. Stock bore. Real easy to install. He felt the difference in power immediately. Front wheel easily comes up with no clutch pop. Highly recommended.

Just what you expect from Wiseco

Just installed the Wiseco standard bore piston kit in my 2004 RM125. It was fairly easy to install, and the quality of the product is evident as soon as you take it out of the box. My bike is back to its old snappy, revy self again! Thanks Wiseco, and thanks MotoSport!

Good Piston

I just installed this piston in my 04 CR250. It is alive and fast as ever. Everything went together well and was easy to install. The only complaint is you get a little piston slap every once and a while, but that is it. The bike is fast and runs great. As always customer service at motosport.com is awesome.

It worked but going to cast

Installed this in my 200EXC when I did a complete rebuild last summer. It ran great, had great power, 215psi compression from installation until I pulled it out last week with 90 hours on it. It did me well for almost 3000 miles of singletrack, desert blasting, a trip to Moab, etc. My only complaint is that the forged Wisecos do run much noisier compared to a cast piston because of the increased cylinder-to-piston clearance required. Excessive piston slap can be heard both when the engine is cold and at operating temp. I put in a cast piston this go-round and will from here on out.

A: If the cylinder has an exhaust port bridge going across the center of port, then yes you will need the holes. If it just has a full size hole for the exhaust port with no bridge in between, then you do not need to drill holes.
