VMC has created a superior class cylinder with this lamellar for the RV-A 100 cylinder.

The technical solutions on this cylinder allow for performance that was previously reserved for long-stroke cylinders.

The cylinder is made of aluminum with a Nikasil-coated barrel and lamellar intake.

The head is CNC machined, with a viton gasket and secured with eight M6 bolts.

It has a bore of 54 mm and a stroke of 43 mm, 8 transfers 

Exhaust port with bridge with an outlet diameter of 28 mm and stud spacing of 52 mm

Phases 113° intake and 171° for exhaust

The manifold has an internal diameter of 25 mm and is equipped with a four-petal reed pack.

Included in the kit are the original valve closure cap screws and a kit of paper gaskets of different thicknesses.

Recommended carburetor size: 19 - 24 mm

Special kit of harmonic steel washers with preload

specifically to compensate for the play due to thermal excursions of Vespa cylinder studs.

These washers are fully compressed at 2 kgm (20 N/m) 
(tightening of Vespa studs) which usually falls within the
Piaggio guidelines between 1.7 and 2.2 Kgm

and compensates for the loosening of the studs subjected to heating and elongation.

Dimensions:

internal diameter 8.4 mm
external diameter 18 mm
thickness 2 mm
washer height at rest on average 2.4 mm
average excursion 0.4 mm

Special kit of harmonic steel washers with preload

specific for compensating the play of thermal excursions of Vespa cylinder studs.

These washers are fully compressed at 1.3kgm (tightening of Vespa studs)

and compensate for the loosening of the studs subjected to heating.

Dimensions:
internal diameter 7.5mm
external diameter 16.8mm
thickness 1.8mm

washer height at rest 2.18mm
excursion about 0.38mm

7-port aluminum cylinder, shell moulding technology, bore treated with Nikasil

Bore diameter 60mm, Stroke 51mm, Displacement 144cc, EXHAUST PORT WITH BOOSTERS

Main Transfer Phases 128° Exhaust 188°, exhaust stud spacing 60mm, oval exhaust outlet diameter 32mm

The exhaust can be slightly filed to 36mm to fit our Evo SeiDue and Kifly 62 exhaust pipes

Piston with 2 steel Rik rings, complete with pin and clips.

Die-cast aluminum head with SIDE spark plug and 4 additional fixing screws.

Squish 1.1mm ± 0.1mm. Tightening torque for M7 studs: 11÷12 Nm, Tightening torque for M6 screws 10÷11 Nm

Complete with bolts and cylinder gaskets in various thicknesses.

It is a cylinder suitable for extreme modifications.

Mounted with a VMC Evo 62, it requires a close-ratio gearbox and more generous expansion exhausts like the VMC Kifly 62 to reach powers of around 30hp

Bore diameter 60mm Stroke 51mm Displacement 144cc SINGLE PORT EXHAUST

Main Transfer Phases 126° Exhaust 186°, exhaust stud spacing 56mm, exhaust outlet diameter 32mm

Piston with 2 steel Rik rings complete with pin and clips.

Die-cast aluminum head with SIDE spark plug with 4 additional fixing screws.

Squish 1.1mm ± 0.1mm. Tightening of M7 stud nuts: 11÷12 Nm, Tightening of M6 screws 10÷11 Nm

Complete with bolts and paper cylinder gaskets of various thicknesses.

It is a versatile cylinder that is suitable for both mild and more extreme tuning.

With more generous expansion exhausts like the VMC EVO 52, it transforms into a classic 2-stroke racing engine.

Installed with the Vmc Siluro Sport, the cylinder transforms into a fast touring engine with generous torque from low revs and excellent top-end power.
