If you want to upgrade your two-wheeler for everyday street use, have a look at this excellent pack: Stage6 Tuning Kit 50cc MKII Evolution 1. We picked only premium quality components so you don't have to spend time and effort on looking for parts that perfectly complement each other.


Cylinder Stage6 MKII 50cc

Developed in collaboration with MXS Racing. It comes with a 2-ring piston, is made of Nikasil-plated aluminium, has 5 transfer ports and an oval-shaped exhaust port. The most important technical innovation: 2 additional intake ports which result in a performance comparable to a 1-ring piston racing cylinder.


Exhaust Yasuni Z

The Yasuni Z exhaust is a tested and tried (and accordingly very popular) exhaust for 50cc OEM/OEM quality and 50cc sports cylinders. Acceleration is improved, top speed is slightly increased.


Carburetor PHBG 19mm

Racing carburetor "Black Edition" PHBG 19mm by MotoForce will improve the performance of your engine considerably. It has a separate oil injection and a vacuum port. Starter is a manual cable choke.


Definitely a perfect compromise between reliability for everyday riding and outstanding performance. Needless to say, you can optimize performance by adjusting the carburetor (jetting) and variator (weight and spring adjustment).

And to round it all off for maximum power, we recommend running this set-up with a Malossi CDI. This should add up to 10hp / 7.5N.m torque.

    Not available.
    MotoForce, a manufacturer specializing in parts and accessories for powered 2-wheelers, with a MotoForce Carburetor "Black Edition" PHBG 19mm for a very good price. A carburetor that will noticeably increase the output of your engine. It has a vacuum and an oil injection port. Manual cable choke. The advantage of this version is its float bowl screw allowing for quick changing of the jet. The black paint adds a "racing" touch. We recommend getting a set of jets so you can properly adjust your carb. Note: make sure you have a proper manifold for rubber mounting, this is not a solid mount carb! Learn More
