WISECO Forged Piston – Ref. W4577M09750
Forged aluminum piston by WISECO, designed for engine rebuilds and classic roadster restorations. With a diameter of Ø 97.50 mm (oversize +0.05 / letter 050), this standard compression piston is intended for engines bored to +0.05 mm. Its forged aluminum construction ensures a homogeneous part that meets the thermal and mechanical demands of 600 cc single-cylinder engines.
Ideal part for engine reconditioning: boring, installing rings, and checking piston-cylinder clearances should be considered during replacement. The forged design prioritizes load-bearing capacity and longevity under varied riding conditions, from daily use to long journeys.
