WISECO Forged Piston Kit Ø89.35mm - Ref. K1642

Designed for the restoration and reboring of Big Twin engines, this WISECO piston kit provides a reliable replacement part for heavy roadsters. The forged piston offers a more homogeneous structure than cast parts, suitable for the thermal and mechanical stresses encountered on large air-cooled single and twin-cylinder engines.

• Brand: WISECO
