170cc Ø67mm MALOSSI kit for 125 4-stroke motorcycle APRILIA RS, RX, SX, TUONO 125 EURO 3, EURO 4

Please note, part not approved on the road, prohibited on public roads, does not respect the engine capacity of 125cc!

High quality, both from its MALOSSI brand and its design! This kit offers a lot of torque and power thanks to its cylinder pushed to a real 167cc (compared to 125cc for the original), the diameter of the whole is therefore 67mm! Delivered with an unrestrained CDI unit which uses the injection parameters to provide the correct air/fuel ratio to the engine, the unit also modifies the rev limiter! The whole thing therefore offers you 1000 more revolutions to have fun in the red zone, which means that when you shift to a higher gear, you are still in the power mode. The cylinder is made of aluminum, the piston is extra compact with three segments but also lightened and reinforced with enlarged heat exchange surfaces, the segments are special for optimal resistance, minimum friction and maximum compression. In short, it can radically increase power with complete peace of mind with quality equipment.



Finally, the electronic unit called Force Master 2 is programmed with 4 different curves which each influence and regulate the fuel flow, which allows you to have excellent carburetion/fuel settings in each condition and programming levels.



Don't hesitate to download the official PDF from MALOSSI explaining from A to Z everything you need to know about this kit, the electronic box and more! The piston in combination with the original cylinder head offers a super compression ratio. Only SP98 should be used, a sports exhaust like the TURBOKIT without catalyst (complete line) is strongly recommended! Open your air box further to take in more air (or install a sports filter). A sprocket with one or two more teeth is recommended!
