Vespa V50 PK50 PK80 PK125 Prim 125 ET3 Ape 50 Pinasco Zuera SRV reed valve 135cc Cylinder Kit Ø57.5mm

This performance cylinder is manufactured from aluminium and is provided with a high end bore lining material ensuring excellent thermal properties and a solid endurance. The exhaust port is wedge-shaped with a 66% chordal dimension within the 57.5mm bore. The 8mm exhaust mounting studs are 52mm apart and the unmodified port timing is 125° to 185°.

The cylinder head is held in place by eight bolts and the centrally located long-thread spark plug opening will require a modified cooling hood to be fitted. The original spark plug opening can be sealed using the specially designed stopper included with the kit. Full Italian and English instructions are included in the delivery. A positioning shoulder is included in the design to ensure a centrally positioned cylinder head.

The plated aluminium piston weighs 169gr. and is equipped with a single 1mm thick piston ring and a bi-conic gudgeon pin. In order to fit this cylinder the upper part of the flywheel casing on the engine will require modification. Full English and Italian instructions are included with the kit.

 

Developed on the racing fields, the "Zuera" thermal group is also suitable for touring use, the exhaust and intake diagrams have been designed to have the right compromise between maximum torque and maximum power, allowing the engine to “Push” in any operating condition without supply gaps and failures. The central spark plug head with 8 studs guarantees maximum performance and prevents deformation of the sealing surfaces.
The new “Zuera” thermal group is exceptional in both daily and competitive use.
