Cylinder and control unit kit Athena 180cc Yamaha MT 125 15-16

Athena 180cc cylinder kit with GET Boost control unit for Yamaha MT 125 2015-2016.

Here you’re not just changing a part, you’re transforming the engine. You go from 124.7 cc to 180 cc, which means a clear change: more mid-range torque, a much more direct throttle response, and an engine that stops being just adequate to really start pushing.

The increase in displacement gives the bike more power where it’s most needed, in acceleration and recovery. You’ll notice you no longer have to rev each gear so high to get a response; the engine fills earlier and maintains its thrust more consistently.

The aluminum cylinder with high silicon content improves heat dissipation, which is key when increasing displacement. The forged piston is designed to better withstand the extra load and reduces internal friction, keeping the assembly stable even under demanding use.

The real difference with this kit is in the electronics. It includes the additional GET Boost control unit, already configured for this cylinder, which adjusts the injection so the engine can take advantage of the increased displacement without errors or lean mixtures. It connects directly to the injector and throttle body, without modifying the original ECU.

Without this electronic management, the engine will not work properly. The kit is designed to function as a complete system.

Includes cylinder, piston, rings, wrist pin, gaskets, and electronic module with wiring, ready to install the complete assembly.
