Piaggio C-One Crankshaft C.39,3 connecting rod 85 RB Racing

Crankshaft 39.3 stroke, 85 rod RB Racing for Piaggio C-One crankcase.

If you are building a racing engine on the Malossi C-One crankcase, you need a crankshaft capable of withstanding the extreme demands of racing without flinching. The Piaggio C-One 39.3 stroke, 85 rod RB Racing Crankshaft has been developed specifically to extract every horsepower from your engine, eliminating the vibrations that reduce power on the track.

This component stands out for its 85 mm CNC-machined connecting rod, which ensures structural strength far superior to conventional cast rods. Its 75 mm webs increase pre-compression in the crankcase, forcing a faster and more direct intake of mixture toward the transfer ports. To ensure perfect concentric rotation at high rpm, it features precision balancing by means of 6 tungsten slugs, a material of extremely high density that stabilizes the crankshaft without the need to drastically increase its volume.

With a total weight of 1590 grams, it provides the inertia needed to keep the engine pulling with constant force.

Attention! This crankshaft is compatible with Piaggio 50 scooter engines and Malossi C-One engines
