ATHENA crankshaft for PIAGGIO 50cc liquid or air engine. This crankshaft is in our eyes one of the best in original 39.30mm stroke. With its increased head axis (crank pin), its perfect balance, its machining from the most dignified materials, its reinforced connecting rod, its increased cage (thicker), its revised and corrected lubrication, its two ultra reinforced cages ...
It is really great, yet very inexpensive. It will be able to withstand speeds of over 15,000 revolutions / minute without any problems, it will withstand the torque and revolutions of all your 50cc and 70cc kits, even the most efficient ones. The finish is flawless and its studied solid masses will offer you much more pre-compression and therefore performance. Comes with a super reinforced 12mm cage.
