Cylinder -PARMAKIT 135 cc SP09 Evo-C- Vespa PV125, ET3 125, PK125

short facts:

• bore: 58mm
• stroke:51mm
• capacity:135cc
• common rod length:97mm
• spark plug position: lateral
• cylinder head: two-piece
• piston: forged
• diameter outlet flange: 36mm
• distance stud bolt: 62mm
• spindles necessary: yes
• exhaust shape: oval, without web

Compared to the normal versions, the EVO cylinders have a heavy-duty forged piston, and with 1mm more diameter in the bore, also more displacement. Equipped with the right components, such a cylinder already delivers plug and play over 20 hp at less than 10000 rpm.

The 'C' in the Parma kit name stands for Classic, which refers to the conventionally designed exhaust window. Compared to the normal EVO cylinder (without 'C'), this one is manufactured without a bridge in the middle of the exhaust.

The engine housing must be extended to 63mm in the diameter of the cylinder base mount for mounting the cylinder.

Due to the large exhaust cross section and the resulting large stud distance of the exhaust of 62mm only suitable exhaust systems can be used.

Conclusion: Extremely powerful cylinder with oval exhaust.
