Full cheek racing crankshaft suitable for Puch Maxi S / N mopeds, as well as Supermaxi LG1 mopeds with a 1-speed E50 engine.
Cleanly finished, 970 gram full cheek crankshaft with corresponding needle bearing.
The crankshaft was designed for use in engines with increased performance. For this purpose, all balancing bores in the cheeks are sealed with aluminum inserts for maximum pre-compression.
The solid connecting rod is fitted with a more stable 16 mm connecting rod bolt.
The two C3 ball bearings and oil seals are already fitted to the crankshaft.
The two ball bearings and the oil seal from the rear gear are also included in the scope of delivery. Depending on the gearbox, only one of the two bearings is required.
The needle bearing is also included in the scope of delivery.
Quality product from the Portuguese manufacturer Rito.
