with cylinder head,
M6 exhaust studs w/ SIP data
sheet

FOR RACE USE ONLY

The stairway to tuning heaven: the 50cc POLINI Cylinder Kit is the perfect start to power performance. Robust and solid basis, hot acceleration and sporting features. POLINI has turned out a really sporting cylinder with this tuning kit with lots of surprising features. 5 transfers move with perfect flow. High quality ASSO pistons have 2 piston rings to guarantee a clean seal. Those who are familiar with Dremel and Co. can get even more performance out of this kit.

Conclusion: POLINI offers a powerful performance 50cc tuning cylinder here. This is the real deal when tuning with original cubic capacity. For those who lust for more power, this cylinder offers a great deal of tuning potential. In this case, the motor casing must be modified.

 

Cast iron/ 38.4mm bore/ 5 transfers/ 49.80cc

Cast iron cylinder, 43mm stroke, 5 transfers, divided into 4 auxiliary transfers and a boost port, pistons with 2 piston rings (1x square, 1x L-ring) and boost port side cutout, 6mm exhaust studs, original POLINI cylinder head included in delivery. Compression 9.9:1, including gasket set. Jets should be adjusted.

Fits all Vespa 50/PK/XL/XL2 models, except PK automatic. Transfers match the originals, casing must not be modified.

 

SIP-TIP: Main jet 60-65 and new spark plugs are mandatory. We recommend a longer transmission, for example, the PINASCO pinion. Your motor will be even more sportier with a 16/16 carburettor, original exhaust with a wider manifold or the SITO Banana.
