ATHENA Forged 4T Racing Piston 87.97mm

The 4T Racing ATHENA forged piston with a diameter of 87.97 mm represents engineering excellence in the world of motorcycles. With over 40 years of experience, ATHENA stands out as a leader in the motorcycle spare parts sector, offering forged pistons through an innovative reverse extrusion process. Each piston is precisely manufactured using CNC (Computer Numerical Control) machines, ensuring dimensional tolerances of less than 0.01 mm.

The special silicon-based aluminum alloy used in production ensures not only reliability comparable to the original but also superior strength and high performance. The carefully polished profiles optimize the flow and propagation of the flame front, contributing to smooth and powerful engine operation.

Engineered in Italy by the ATHENA Research and Development team, this piston undergoes rigorous testing both on the bench and on the track, ensuring excellent results in competitive conditions. The kit includes not only the piston but also the pin, circlips, and the ring kit, all designed to be easily replaceable and interchangeable. It is important to note that ATHENA products intended for displacements and powers exceeding those allowed by road regulations are exclusively for competitive use, and the company disclaims any responsibility for uses not in compliance with national regulations.
