Cylinders are the aftermarket engine parts that Athena has been continuously investing in for more than a decade to improve their production and performance. The company's engine cylinders and thermal units are recognized worldwide for their performance, durability and reliability. Engineered entirely in Italy by Athena's R&D department, which has the strength of in-house know-how and state-of-the-art tools to design and test each cylinder, they are coated with motor-nicksil, a nickel-silicon coating developed by Athena to achieve optimal smoothness and wear resistance.
The Big Bore oversized thermal assembly developed by Athena provides a performance increase noticeable along the power curve, while still maintaining the same reliability as original components.
The kit includes the high quality aluminum cylinder with increased bore, cylinder head, complete piston with piston pin and rings, exhaust valve kit and necessary gaskets.
All components of the thermal assembly have been designed, manufactured and tested with stringent testing on the track and on the static and dynamic dyno to ensure maximum resistance to high pressures and temperatures.
This thermal assembly can be installed without making any modifications to the motorcycle crankcases.
