Kit 170cc MALOSSI Ø58mm, cylinder / piston + electronic box calculator for YAMAHA CYGNUS X, BW'S and X OVER 125cc

You were waiting for ... The big kit that'll finally make your roar 125cc maxi scooters YAMAHA CYGNUS X, and X OVER BW's 125cc 4-stroke injection. Here, the famous Ø58mm kit that is increasingly delivered with the electronic calculator multi curve.

 

 

As usual MALOSSI has made a powerful kit, strong, torquey and very high-end. This little monster will project your engine of 125cc to 170cc real extreme performances. MALOSSI has for this thermal group found the perfect ratio race / diameter, this cylinder serras without problem supported by your crankshaft of origin.

 

 

It is already running in competition and endurance is therefore to say if it is tested ... Force Master 2 is the electronic box that allows to change the injection to fit perfectly to the new 4t Malossi thermal unit. This box has been programmed with different programs to be perfectly matched to your vehicle, whatever its configuration! With this casings 4 curves are offered ...

 

- curve 1: best performances with the original cylinder
- Curve 2: Malossi cylinder and original muffler
- curve 3: Malossi cylinder and modified exhaust

- curve 4: excl.

 

Let's see instead how MALOSSI did to increase the performance of the high engine, it did not stop of course increased the diameter of the piston cylinder! Here are the technical characteristics of the kit:
