VMC SUPER G 2.0 cylinder kit for 2-channel housing - Vespa Largeframe 125 and 150

The VMC SUPER G 2.0 is a cast iron cylinder kit for Vespa Largeframe engines with 2 transfer ports. This version differs specifically from the 3-channel version: pistons and a specific adapter plateare matched to the 2-channel base so that the kit also works properly on original, little-machined engine cases.

Largeframe 125 and 150 2 transfer ports Ø 63 mm 6 transfer ducts 8-bolt head Outlet nozzle with O-ring

Concept: Plug and play with reserves

The shape of the transfer ports on the cylinder base is deliberately conservative. This means that the SUPER G 2.0 can be fitted to many 2-channel housings without the need for milling work on the housing. If you want more throughput and power at a later date, the windows on the base can be specifically widened and adapted to the engine housing cross-section.

Material and exhaust design

Cylinder: 6-overflow design in high-quality spheroidal cast iron.
Exhaust: innovative design to optimize the torque curve for powerful acceleration from low engine speeds and a clean band up to high engine speeds.
Important note: In order to maintain the design, we expressly advise against changing the shape of the exhaust.

Cylinder head and combustion

Head: Aluminum head with special ribbed shape for better heat dissipation, recessed squish band geometryand 8 mounting points.
Spark plug: Lateral plug position with central electrode position in the combustion chamber for stable combustion.

Technical data and scope of delivery

  • Bore: Ø 63 mm
  • Transfer ports: 6
  • Timing (approx.): intake 118°, exhaust 176°
  • Piston: VMC aluminum piston, 2 piston rings, biconical piston pin
  • Gasket set: Paper gaskets in various thicknesses (basic)
  • Exhaust port: Steel, bolted to cylinder, sealing via O-ring
  • Note: This version includes pistons and adapter plate specifically for 2-channel housings

Setup tip

For a harmonious result, VMC recommends a clean rotary valve intake with suitably adapted intake control angles - depending on the concept via a sports crankshaft and or by machining (milling) the intake on the engine housing.
A modern box-type exhaust system is particularly suitable
The SUPER G 2.0 delivers a very driveable torque even on moderate setups. If you want more later on, you can selectively extend the basic transfer ports at the base of the cylinder.

Conclusion

The VMC SUPER G 2.0 is a consistent solution for Vespa Largeframe 125 and 150 engines with a 2-channel housing: easy to install in its basic state, with a clear technical reserve for later adaptations. The modern exhaust layout and the 8-bolt head are aimed at a wide power band suitable for everyday use and clean thermal control.
