Athena S410250006129 Base Gasket Kit Kawasaki - 0.3mm KX125

The Athena S410250006129 base gasket kit is engineered specifically for 2003 Kawasaki KX125 two-stroke motocross engines with a precision thickness of 0.3mm. This base gasket plays a critical role in sealing the cylinder to the crankcase while allowing riders to fine-tune compression ratios and power characteristics through strategic gasket thickness selection.

Key Features:

• Precision laser-cut construction ensures exact fitment and reliable sealing
• 0.3mm thickness specification for controlled compression adjustment
• High-temperature resistant materials withstand extreme combustion chamber conditions
• Rubber-coated steel construction provides superior spring-back and tensile strength
• Manufactured in state-of-the-art computer-controlled facilities to meet or exceed OEM specifications
• Compatible with stock bore and big bore cylinder configurations

Athena base gaskets feature soft steel construction with rubber coating, designed to compensate for surface irregularities and maintain a perfect seal even under high cylinder pressures. The 0.3mm thickness allows engine builders to adjust compression ratios and squish clearances for optimal performance in competition or recreational riding applications.
