Forged Wössner high-performance piston for the 47 mm Gilardoni italkit Puch cylinder kit.
ZME forged piston developed by MBR with a 1 mm rectangular piston ring with internal fuse (IS), which is often used in the Mofacross / Mofacup scene.
Optimal material structure, flow-optimized shape and large-diameter inlet windows 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 relevant piston rings, their stems and locking types on the legend in the pictures.
The molybdenum coating, in combination with oil, results in technologically advanced wear protection with outstanding sliding properties.
