Dirt Bike

Dirt Bike

With a collection of Pro Motocross, AMA Supercross, and off-road motorcycle titles, JE has been at the forefront of off-road four-stroke performance since manufacturers began introducing them to the sport. JE’s long history of working with teams such as Pro Circuit Racing and JGRMX have led to the development of the Pro Series line of pistons for a long list of dirt bike and off-road applications. Built for top performance and reliability with Forged Side Relief designs and internally and externally braced forgings, Pro Series pistons are available in multiple compression ratios and feature two-ring designs for many applications. Unlock your machine’s true potential.

“We’ve worked closely with JE for more than 10 years to build a race-ready piston that performs at the highest level for our riders and our customers. The length of our relationship speaks volumes about our collective success.”

Mitch Payton, Pro Circuit Racing
