This specialized rolled-on application creates a bond 10 times stronger than traditional spray-on coatings, significantly reducing friction and helping to eliminate the risk of cold seizures. Whether you are building a KTM 350 SX-F service kit or performing an annual refresh on your Husqvarna FE350, this performance package ensures your motor stays cooler and runs smoother under the most demanding racing conditions.

Top Features Namura Top End Piston Kit:

• Complete All-In-One Box: Includes the performance piston, rings, wrist pin, clips, top end bearing, and a premium top end gasket kit.

• Machined Smooth Heads: Designed to reflect combustion heat and reduce carbon buildup; tests have shown this can improve horsepower and fuel economy by up to 6%.
• Hypereutectic Casting: High silicon content provides lower expansion rates and superior wear resistance to withstand extreme cylinder temperatures.
