Athena Cylinder 183cc Yamaha YZF 125 R / WR 125R/X

Malossi presents us with one of the most complete and most powerful cylinder kits. A good preparation, in this case, for Yamaha 125cc engines. In addition to the significant increase in displacement, which will reach 183cc (a 50% increase!! almost nothing), the kit includes a control unit.
This control unit has been programmed with 4 different power curves so that it can be perfectly installed in your vehicle, whatever its configuration!
The kit includes the control unit, the cylinder, the piston, the rings, and the necessary gaskets for assembly.
The cylinder head is not included, as is usual in 4-stroke kits.
The material, as we are used to from the Italian manufacturer, is of the highest quality.
It goes without saying that this is a kit for connoisseurs.

curve 0 : original exhaust, original cylinder, original cylinder head, original camshaft, and original filter
curve 1 : original exhaust, Malossi cylinder, original cylinder head, original camshaft, and original filter
curve 2 : modified exhaust, Malossi cylinder, original cylinder head, original camshaft, and original filter
