The Super Duty Piston is designed for serious riders who demand durability and enhanced performance from their engines. With its advanced features, this piston provides an exceptional fit and smooth operation, ensuring your bike performs at its best when it matters most.

Precision Engineering for Optimal Performance

Each Super Duty Piston is crafted with an anodized top ring groove and crown, ensuring a perfect seal and reducing wear over time. Its Line2Line abradable skirt coating is meticulously applied to create a zero initial fit, allowing for a tight and quiet running clearance as it hones in during use. This means you can enjoy a more efficient ride without the noise and hassle of inferior pistons.

Innovative Features for Enhanced Longevity

This piston is equipped with premium Hastings top rings made from steel nitride, featuring a ductile Napier second ring for superior oil control. This combination not only improves engine efficiency but also extends the life of your motor, giving you peace of mind on every ride. The forced wrist pin oiling system further enhances lubrication, ensuring your engine runs smoothly under all conditions.

Customizable Options to Suit Your Needs

The Super Duty Piston comes in an M8 version with a flat top, designed to accommodate 1mm oversized valves. This versatility allows you to customize your bike's performance to fit your unique riding style. Whether you're hitting the trails or cruising down the highway, this piston adapts to your needs for a truly personalized experience.
