ATHENA Big Bore Cylinder Kit Ø 83 mm, 290 cc - P400485100036 (Includes Piston and CDI)

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 guarantee 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 complete piston with the piston pin and rings, all the necessary gaskets, and increased bore aluminium cylinder with CNC machining to grant tolerances of a hundredth of a millimeter during the whole production process.

The kit also includes an additional CDI designed by GET technicians to maximize engine performance.

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.
