Spears Racing Thermal Barrier Crown Coating.
Elevate the durability and performance of your Kawasaki Ninja EX650/ER650 with the Spears Racing 700cc Overbore Piston Kit, featuring JE Pistons’ proprietary Thermal Barrier Crown Coating. This advanced ceramic gold coating is designed to combat the destructive effects of heat, significantly extending piston lifespan while boosting engine efficiency for street and track applications.
Thermal Barrier Crown Coating: Engineered for Endurance
Heat is the enemy of piston longevity, causing annealing (softening) over time through repeated thermal cycles. Without protection, the piston crown absorbs intense heat, leading to material degradation, deformation into an “umbrella shape,” and eventual failure. JE’s state-of-the-art ceramic gold coating, applied in-house, revolutionizes piston performance by:
-
Reflecting Heat: The .0015” thick coating acts as a thermal shield, rejecting a large portion of combustion heat that would otherwise be absorbed by the piston crown.
-
Preventing Annealing: By minimizing heat transfer, the coating keeps the piston material stronger for longer, virtually eliminating softening and extending the piston’s lifespan indefinitely under proper engine conditions.
-
Enhancing Combustion Efficiency: The coating reflects heat back into the combustion chamber, increasing exhaust gas velocity and improving scavenging potential for better power output.
This cutting-edge technology ensures your pistons withstand the rigors of high-performance riding or racing, delivering reliability and performance lap after lap.
