Cylinder kit Athena Racing 77cc (43 stroke) Minarelli Horizontal /CPI/ Keeway 12mm

Attention! : Crankshaft Athena Racing 80cc 43mm stroke required! High performance sport aluminum

Cylinder kit made in Italy by Athena. The thermal advantages of aluminum provides these cylinders with better colling and a higher peak power than cast-iron cylinder. Developed with 3D Solid Modelling software creating virtual simulation and verification of mechanical stresses.

This aluminium cylinder is casted in steel moulds and manufactured by CNC machines to assure millesimal tolerances during all manufacturing phases. The cylinder liner is made with a special silicon carbide and nickel coating mixture to grant the best fluidity of the piston and durability of the cylinder. Manufacturing performed in rooms with indoor temperatures of around 20 degrees, in order to have an excellent control of the boring and of each cylinder quality. Cylinder support surfaces are perfectly parallels in order to eliminate any matching inaccuracy. Supplied with piston and ring, cylinder head, carbon reeds and gasket set with various base gaskets to adjust the squish.
