Carter VMC X1 for Vespa Small Frame mod. ROTARY VALVE

The evolution of modifications in the Vespa world is constantly evolving, and VMC has also decided to create specific casings for Vespa small frame that can accommodate the most powerful thermal kits and larger displacements available on the market. VMC has designed and manufactured casings capable of meeting these needs and has given life to the VMC X1 Casings

The Vespa Smallframe VMC X1 Casings are made of aluminum alloy, cast in sand molds and CNC machined in Italy, and checked for dimensions with high precision instruments.

Compared to Piaggio casings and semi-standard aftermarket versions, VMC casings feature technical improvements that position them at a higher level and make them the essential base for those who want a safe product made by enthusiasts for enthusiasts.

The VMC X1 engine casings have the following technical features:

- innovative fastening system for removable gear wire rods, which, combined with our external rod gear sheaths, speeds up engine change and gear cable tension adjustment

- increased wall thickness for greater resistance to mechanical stress

- a very wide cylinder support base

Sleeve diameter 30 mm
for carburetor: PHBL PHBH -22 - 24 - 25

The venturi hole is Ø 26mm and perfectly fits carburetors of this size. To adapt it to smaller carburetors, it is necessary to file the first part of the carburetor's intake duct. To adapt it to carburetors with a diameter greater than 26mm, it is necessary to slightly file the venturi to fit the carburetor's diameter.
Advantages:

Improves engine performance
Increases power, acceleration, and top speed
Compatibility with carburetors with or without a mixer
Possibility to mount an air filter directly in the box
Stylish and classic look

Mounts on Et3 frames with the side compartment, on Pk frames it is necessary to slightly cut the bulkhead to allow the expansion curve to pass through.

On pre-1976 Primavera frames, the compartment is deeper and may limit the installation of the exhaust.

Designed to give the best performance on 125/185 timing, it adapts to a wider range of timings.

It fits very well with long-stroke 130cc cylinders that have a 32mm exhaust diameter.
