ATHENA EC485-049 THERMAL UNIT CYLINDER KIT

The ATHENA Standard Bore 250CC 77mm Thermal Group for Yamaha represents excellence in the aftermarket motorcycle parts landscape. Designed and engineered in Italy, this cylinder is the result of over ten years of innovation and development by ATHENA, a globally recognized brand for its performance and reliability.

The design of the thermal group has been optimized to ensure superior smoothness and wear resistance, thanks to the motor-nicksil coating, an exclusive nickel-silicon overlay. This engineering approach ensures that the lightweight aluminum cylinder and the coated sleeve can withstand high pressures and temperatures, maintaining consistent performance over time.

The Easy Cylinder Kit Standard Bore includes everything needed for a complete engine overhaul, featuring a standard bore cylinder and a set of specific gaskets. Each component has undergone rigorous testing on the track and in the lab, ensuring that the thermal group can be installed without any modifications to the motorcycle's crankcases, thus facilitating the replacement process.

With ATHENA, your motorcycle can rely on a replacement designed to offer performance comparable to that of the original part, maintaining the reliability and smoothness that every rider desires.
