Big Bore Cylinder Kit With Head Ø 47,6 mm, 70 cc, Pin Ø 10 mm, Domed Head Piston
TECHNICAL ADVICE: The kit is supplied with piston pin-piston Ø 10 mm as the original. In view of the mechanical stress we suggest to assemble the kit with increased pin-piston Ø12 mm (see section Thermic Units). In this case we remind you to replace the original crankshaft with our crankshaft with increased piston pin Ø12 mm (see section Crankshaft).
WARNING: the cylinder head and base gaskets contained in the kit are specifically developed for Athena cylinders kits. Whenever the cylinder kit is disassembled, replace the gaskets with the specific Athena spare gasket kit: DO NOT use OE replacement gaskets.

Description
Athena has been constantly investing in cylinder aftermarket replacement parts for more than ten years, to improve their production and performance.
All the cylinders are entirely engineered in Italy by Athena’s R&D Department which has a strong internal know-how and cutting-edge tools to design and test each piece. They are coated with motor-nicksil, a nickel-silicon coating developed by Athena to obtain smoothness and optimal wear resistance.
Athena’s cylinder kits and its components are recognized worldwide for their performance, durability and reliability.
Athena’s Big Bore Cylinder Kits guarantees an increase in performance that can be observed along the power curve, keeping the reliability at the same level of the original components.
The kit includes the high-quality aluminum cylinder with increased bore, the cylinder head, the piston with domed head with the piston pin and rings, and all the necessary gaskets.
All the components of the kit have been developed to withstand the highest temperatures, pressures and stresses and have been validated by Athena technicians with severe bench and road tests.
This cylinder kit can be installed without making any changes to the engine crankcase.
CAUTION! All Athena products must be used in compliance with the specific national regulations of the member state where it is being marketed or sold. Athena declines all responsibility for any improper use.
