FOR RACE USE ONLY

Welcome to the POLINI world of tuning! Here comes a powerful 75cc cylinder with power at low revs as well. Ideal basis for use by 2 people this item will not become tired even on longer rides or stretches at full throttle!

Thick cylinder walls ensure good heat dissipation and make the POLINI a trouble-free companion.

Conclusion: Powerful cylinder with extra power at low revs. Thanks to the higher compression and the additional channels sportier than the competition. Thermally balanced and long-lasting.

 

Cast iron/ 47mm bore/ 6 transfer ports/ 74.60ccm

Cast iron cylinders, stroke 43mm, 6 transfer ports, pistons with 2 piston rings, exhaust with a width of 27.5mm (chord dimension), 6mm exhaust studs, original POLINI cylinder head included in delivery, compression 11.2:1, incl. gasket set. Jets should be adjusted.

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

 

SIP-TIP: Adjusting main jet and a new spark plug is a must. Transmission recommended here is at least the PINASCO pinion or a 3.72 transmission. The engine is made even sportier by a 16/ 16 carburetter, original exhaust with wider manifold, SITO Banana or POLINI racing exhaust.
