Athena Forged Piston Kit for 4-Stroke 250cc

Upgrade your motorcycle's engine performance and durability with the Athena Forged Piston Kit 250cc. Engineered for demanding 4-stroke applications, this kit provides superior strength and a precise fit, ensuring reliable power delivery for your ride.

Description

Specifically designed for high-performance 4-stroke engines, this Athena Forged Piston Kit utilizes high-grade 2618 silicon aluminum, renowned for its exceptional strength and resistance to extreme temperatures and pressures. A crucial 3% copper additive further enhances heat dissipation, vital for sustained high-RPM operation and engine longevity. While Athena also produces 2-stroke pistons from 4032 silicon, this particular kit is tailored for 4-stroke powerplants.

The precision forging process creates an incredibly dense and uniform grain structure, resulting in a piston that is significantly stronger and lighter than conventional cast alternatives. This advanced tooling ensures the lightest possible product, contributing to improved throttle response, reduced reciprocating mass, and a more efficient engine. Each kit comes complete with an antiwear coated piston, high-quality steel rings, a durable piston pin, and secure circlips, providing everything needed for a comprehensive engine rebuild or upgrade. The meticulous manufacturing guarantees a perfect fit for a 76.97 mm bore with a 13.5:1 compression ratio, specifically for 250 cc 4-stroke engines, delivering the reliability and performance that enthusiasts demand.
