PARMAKIT SP09 Evo-C 135cc cylinder for Vespa PV, ET3 and PK125

135cc cylinders from Parmakit with ultra-hard coated aluminum as a base.

shortfacts:

  • Bore: 58 mm
  • Stroke: 51 mm
  • Displacement: 135cc
  • Connecting rod length: 97 mm
  • Spark plug position: lateral
  • Cylinder head: two-piece
  • Piston: forged
  • Exhaust flange diameter: 36 mm
  • Distance between stud bolts: 62 mm
  • Spindles required: yes
  • Exhaust shape: oval, without land


Compared to the normal versions, the EVO cylinders have a heavy-duty forged piston and, with 1 mm more diameter in the bore, also more displacement. Fitted with the right components, such a cylinder can easily produce more than 20 hp at under 10000 rpm, even when plug-and-play. The 'C' in the Parmakit name stands for Classic, which refers to the conventionally designed exhaust window. Compared to the normal EVO cylinder (without the 'C'), this is manufactured without a bar in the middle of the exhaust.

The engine housing must be widened to 63 mm in the diameter of the cylinder base mount in order to fit the cylinder. Due to the large exhaust cross-section and the resulting large stud spacing of 62 mm, only suitable exhaust systems can be used.

Conclusion: Extremely powerful cylinder with oval exhaust.
