Forged Wössner high-performance piston for the 47 mm Gilardoni italkit Puch cylinder kit when operated with a housing-membrane inlet (GME).
Attention, the piston cannot be used for conventional Gilardoni italkit cylinders which are operated with cylinder diaphragm inlet (ZME).
GME forged piston developed by MBR with a 1 mm rectangular piston ring with internal locking (IS), which is very often used in the Mofacross / Mofacup scene.
Optimal material structure, flow-optimized shape and large lubrication pockets above the piston pin characterize this high-quality racing piston.
The detailed dimensions of the piston according to the technical drawing can be found in the details. You can also find out about the common piston rings, their stems and locking types on the legend in the images.
The molybdenum coating in combination with oil provides technologically advanced wear protection with outstanding sliding properties.
Recommended piston size (coating corresponds to +0.01 mm to +0.02 mm):
Gilardoni italkit Cylinder A (47.00 mm): 46.94 mm piston (in exceptional cases, e.g. when using ASP®).e.g. when using ASPEN: 46.93 mm piston)
Gilardoni italkit cylinder B (47.01 mm): 46.95 mm piston
Gilardoni italkit cylinder C (47.02 mm): 46.96 mm piston
Gilardoni italkit cylinder D (47.03 mm): 46.97 mm piston
Piston ring, piston pin and piston pin retainers are included in the scope of delivery.
Matching add-on parts such as cylinder kits, needle bearings, stroke plates, carburettors, air filters etc. can be found under accessories.
