Athena 170cc Cylinder Kit
Honda CBR 125cc 2007 > onwards models
The Athena 170cc kit for Honda CBR 125cc injection models features an aluminium cylinder with nickel-carbide coating designed with wider water jackets for more efficient cooling. A cast-lite piston with rings, gudgeon pin, circlips and a full top end gasket set. Also included in the kit is the new ECU that dramatically changes the RPM curve of the engine. This comes out at 16.8 HP on the dyno and the graph shows the power coming straight in at 6000 RPM thanks to the new Athena ECU.
