This Wossner forged piston kit features a 56.02mm bore size (55.97mm actual), providing a +0.02mm oversize fitment for specific Cagiva 125 models. Designed and manufactured in Germany, the piston maximises heat transfer and maintains structural integrity under thermal expansion. Its elliptical form reduces localised stress, promoting even load distribution and preventing collapse.
