The Vespa Smallframe Racing Cylinders from VMC for the 125cc models, i.e. with 51 mm stroke, are available in different versions. The most important distinguishing feature between the "GS" and "ET6" models is the material. The ET6 is made of aluminum, while the GS Cylinder is made of grey cast iron. The "ET7" version is also cast in aluminum, but has an additional transfer port as well as a three-part outlet. The cast iron "GS" cylinder is also available with different bores. The 135 variant (58 mm bore) has a forged piston. The 132 (57.5 mm bore) is equipped with a cast iron piston. The 55.6 mm bore version is a particularly interesting option. It can be used to build a powerful Engine in the 125 cc class. All Cylinders are supplied with a lightweight Piston with a 1 mm thick Piston Rings. The scope of delivery includes base gaskets in various thicknesses. This allows the Cylinder to be adjusted to an ideal pinch edge.

Note: For the variant with 144 cc and 60 mm bore, the Crankcase must be spindled 10 mm deep to 64.5 mm. The casing for the Flywheel must be removed above the cylinder base sealing surface.

Conclusion: If you are looking for an uncomplicated, inexpensive but powerful tuning for your Vespa Smallframe, you will find it at VMC.
