PARMAKIT Racing engine housing for Vespa Smallframe engines

PARMAKIT engine housing suitable for Parmakit SP09, W-Force. SixtySix and similar.

New engine case, which has a spindled crankcase diameter and a larger cylinder base mount ex works. This means that a reinforced crankshaft with a larger crank web diameter (max. Ø87mm) can be installed without modifications. The cylinder base mount has two different diameters:

• The larger one has a diameter of Ø65.5 mm and is 7 mm deep, making it suitable for the Parmakit W-Force with Ø60mm (144 cc)

• The second diameter is Ø63mm throughout and therefore fits the 135cc version of the W-Force cylinder

The housing has a mount for the classic 2-pull gearshift of the Vespa V50, PV, ET3 and PK XL models. By enlarging the crankcase diameter for crankshafts up to Ø87mm, the rotary valve inlet can no longer be used. The housing is therefore intended for use with a diaphragm intake manifold. Alternatively, it is possible to use a cylinder with a diaphragm inlet directly on the cylinder.
