Hi, I'm Brian Weaver from JE Pistons here to talk about our Pro Series motorcross part. We have two different styles of pistons. We have our standard JE and we have a Pro Series version of the same part. The standard piston mimics the stock part, both weight and style. The Pro Series is based off a race part that we've been doing for years for most of the high-end motocross teams derived from billets and now forged for just any user. Last year in 2011, JE Pistons was in every motocross and supercross championship engine, including lights both east coast and west coast, supercross, motocross and 450, donations and monster cup. These are the same type of quality pistons that you can get in your engine. The Pro Series part is braced both internally and externally. They're dedicated embossed forging for lightweight. We also reduce the weight by internally milling the internal struts. All the pistons are diamond turned and have exact tolerances for easy fitment. As you can see, this piston has a c What this does is as trapped gases get past the top ring, it has a place for the gases to expand. These pistons have plunge valve pockets for optimization and compression. Please check our website for the most popular applications for your engine at jepistons. com.
