Big Bore Cylinder Group Ø 63 mm 182 cc YAMAHA MT 125 125 cc 2015-2016

The cylinders are the aftermarket engine spare parts in which Athena has been investing for over ten years constantly to improve production and yield. The company's engine cylinders and cylinder kits are recognized worldwide for their performance, durability and reliability. Engineered entirely in Italy by the Athena R&D department, with internal know-how and cutting-edge tools to design and test each cylinder, they are coated with motor-nicksil, a silicon nickel coating developed by Athena to obtain smoothness and optimal wear resistance.

The Big Bore increased thermal unit developed by Athena guarantees an increase in performance that can be found along the curve power, always maintaining reliability equal to that of the original components.

The kit includes the complete piston with piston pin and rings, the necessary engine gaskets, and the cylinder with increased bore in a special aluminum alloy, machined with CNC machines to guarantee centesimal tolerances in all processes.

The kit also includes a Plug&Play replacement control unit designed by GET technicians, which can be installed using the original connector and wiring directly. A dry map and a wet map are installed in the control unit, which can be selected using the appropriate selector supplied in the kit. With the purchase of the GET WiFiCOM device, sold separately, it is possible to quickly and intuitively customize some mapping parameters, such as carburetion and spark advance, in absolute safety, by connecting your smartphone or tablet to the control unit via the free app WiGET.

All components of the thermal unit have been designed, created and tested with severe tests on the track and on the static and dynamic bench to guarantee maximum resistance to high pressures and temperatures.

This cylinder kit can be installed without making any modifications to the motorcycle crankcases.
