Racing Cylinder PINASCO 125cc

for Vespa 90-125/PV/ET3/PK/S
Ø 55mm, aluminium, 3 ports,
stroke 51mm, conrod 0,0mm,
2 piston ring(s),
with cylinder head


PINASCO has always been known for first class high quality workmanship, an eye for durability and fitness for daily usage. The PINASCO 125cc was the very first aluminum tuning cylinder for the Vespa to hit the market. Since the 70's, this classic tuning part has played a major part in hectic city traffic and daily usage for running small errands.

The Nicasil coated 125 cc cylinder comes with the original 55 mm bore. At the moment, this is the only available 125 cc cylinder made in Italy. The 3 transfers, an ASSO piston, a somewhat sportier timing than the original and the original PINASCO cylinder head make waves with 7.2 PS at 5600 rpm's.

PINASCO recommends a 82 main jet for 19/19ers and 95 main jet for a 24er carburetor, ignition 18°, Bosch W4AC spark plugs or NGK B7HS. for those wanting a little more refinement, then use a 19/24 carburetor and the PINASCO Banana exhaust.

Conclusion: Very good cylinder for 125cc town traffic. Hearty and durable. The aluminum material with nicasil lining allows full throttle handling.


Aluminum/ 55 mm bore/ 3 transfers/ 121.17 cc's

Aluminum cylinder, 51 mm stroke, 3 transfers, piston with one piston ring, 8 mm exhaust studs, original PINASCO cylinder included in delivery, gasket set also included. Jets should be adjusted. Fits all Vespa PV/ET3/PK/XL/XL2 models, except PK automatic. Transfers do not need modification.


SIP-TIP: main jet adjustment and new spark plugs are a must. We warmly recommend an original exhaust with a wider manifold or the original PINASCO Banana.

OEM Numbers (for the purpose of comparison)  25030794 (PINASCO)
