Polini 133 racing cylinder available!
This is a classic
racing cylinder from Polini for the Vespa Smallframe models PV/ET3/PK/XL/XL2 models, except PK automatic. This tuning cylinder is the revised version of the legendary 133 Polini and offers plug & play high durability with plenty of torque. But the cylinder also offers plenty of potential for ambitious tuning of your Vespa, beyond 20 hp. If that's not enough:
Polini 152 Big Evo cylinder
The main innovation of this "racing version" compared to the classic 133 is the cylinder head, which is made of cast aluminum with a high silicon content. The head also has additional cooling fins on the underside. This means that heat is dissipated much better, both from the cylinder itself and from the head. The copper gasket not only conducts heat better, it also contributes to a much better seal between the cylinder and head. The layout of the cylinder is unchanged and is determined by the six transfer ports. The ASSO piston is made of die-cast, which gives it very good durability and low weight. 57 mm bore provides a displacement of 130 cc with a 51 mm shaft and an impressive 138 cc with a 54 mm shaft [su_spacer][su_button url="https://www.scooter-center.com/product/P1400050R" target="blank" background="#CF170A" size="8" center="yes" radius="0" icon="icon: flag-checkered"]Order Polini 133 now[/su_button][su_spacer][su_spacer][su_spacer]
Racing cylinder of the K5 in the ESC
The cylinder is ridden very successfully in the ESC (European Scooter Challenge) in the K5 class and has approx. 15 hp when "plugged in". We already had this cylinder, extremely revised, with 30 hp on our test bench!

This is the original press release from Polini about the cylinder: POLINI CYLINDER KIT FOR VESPA 125 PRIMAVERA ET3 WITH NEW CYLINDER HEAD: RACING GENERATION Polini Motori has redesigned the popular cylinder kit for the Vespa 125 Primavera ET3. This is now also available as a RACING version with a specially developed cylinder head for better cooling. The cylinder head itself is also available separately. TECHNICAL DATA: The cylinder is made of cast iron with lamellar graphite. This gives it a self-lubricating effect and makes it highly resistant to mechanical loads. This reduces the working temperature and prevents possible power losses. The cylinder has a bore of 57 mm and has 6 transfer ports. The piston is made of chill-cast light alloy with a high silicon content and has two "S10" chrome-plated piston rings. The aluminum cylinder head is equipped with two fins, which dissipate the heat better. Cooling and compression ratio are optimized. The new copper gasket prevents gas from escaping between the cylinder and cylinder head and facilitates heat exchange [su_spacer][su_button url="https://www.scooter-center.com/product/P1400050R" target="blank" background="#CF170A" size="8" center="yes" radius="0" icon="icon: flag-checkered"]Order Polini 133 now[/su_button][su_spacer][su_spacer]
