ATHENA Forged 4T Racing Piston 87.97mm for Husqvarna/Ktm

The 4T Racing ATHENA forged piston with a diameter of 87.97 mm is designed for Husqvarna and KTM models, representing excellence in motorcycle performance. With over 40 years of experience, ATHENA stands out in the motorcycle spare parts industry, offering forged pistons through an innovative reverse extrusion process.

Manufactured using state-of-the-art CNC machines, these pistons ensure extremely precise dimensional tolerances, less than 0.01 mm. The special silicon-based aluminum alloy used in production guarantees reliability comparable to that of original components, while the superior strength and performance are the result of an engineering design developed in Italy by ATHENA's Research and Development team.

Each piston undergoes rigorous bench and track testing, ensuring that its performance meets the expectations of the most demanding motorcyclists. Equipped with rings that reduce friction with the cylinder, this piston optimizes engine output. The kit includes not only the piston but also the pin, circlips, and the ring kit, all designed to ensure a hassle-free replacement and interchangeability.

It is important to note that all ATHENA products intended for displacements and powers exceeding those allowed by the road code of the user's country are designed exclusively for competitive use. ATHENA disclaims any responsibility for any use contrary to national regulations.
