POLINI FOR VESPA 50 4T EURO 5

Polini Motori and Vespa: a duo with more than 70 years of history. An indissoluble bond over time, which still excites all fans today.

The relationship between Polini and the most famous scooter in the world has solid roots and continues to mark the collective imagination. The Vespa equipped with Polini is distinguished by its decisive thrust, in any driving situation. There are those who love speed, those who love the fluidity of driving, those who love quick recovery: Polini Motori opens up a range of unique emotions without comparison.

How is that result achieved? It is essential to replace the control unit by updating the ECM Polini “ENGINE CONTROL MODULE” with valve springs.

Replacing the control unit is essential for any type of assembly .

Studied and fine-tuned thanks to feedback from Polini's competition department, the update of the Polini control unit allows you to choose between 3 different mappings, thus giving the end user the possibility to further customize your vehicle.

The addition of valve springs inside the package allows the limiter to reach up to 10,000< /strong> engine revolutions with a specific result in speed and an increase in performance that guarantees a more dynamic and fluid ride.

Depending on the assembly steps of the scooter, it is important to match the specific mapping developed by Polini.

Mapping 1

This is the simplest assembly step, since it is enough to dismantle the original control unit and attach the Polini ECM for Vespa and Liberty 50 4T Euro 5; In fact, it is a plug & play easy installation. Only the replacement allows the revolution limiter to be increased from 7,500 to 8,100 rpm.

With this mapping it is possible to maintain the original Piaggio engine, but it is advisable to mount the Polini variator (241.737) and the Polini silencer (190.0079).

The assembly of the Hi-Speed variator allows a small increase in speed and acceleration. p>

To improve engine efficiency, Polini suggests the installation of the Polini Original silencer: made with lines reminiscent of the original, it has a refined but discreet character. Made entirely of steel, it stands out for its incredible lightness.

With this mapping the speedometer goes from 45 km/h to 50/53 km/h.

Mapping 2 strong>

With the second mapping you enter the heart of customization and take the vehicle to a higher level . It is essential to have a professional when working on the engine. First of all, it is important to know that it is necessary to change the original engine valve springs with Polini ones (already included in the control unit package), which allow the engine limiter to be raised. at 10,000 rpm without valve problems.

This mapping also works with the original engine, but Polini recommends combining the Polini variator (241.737), the Polini silencer (190.0079 ) and the Polini oversized air filter hose (223.0131).

With this process you go from 45 km/h to 56/60 km/h.< /p>

Note – To replace the springs it is necessary to dismantle the engine. With a small additional step in terms of cost, an expanded cylinder and ratios (using mapping 3) can also be fitted with a final result of higher performance.

Mapping 3< /p>

At this point, there is very little left to do to have a real Vespa sprint with a maximum speed of 70/75 km/h. If you have already done important work with mapping 2 by reaching into the engine to mount the spring, with a small additional step you can configure your vehicle with mapping 3 and have a complete job at maximum performance.

< p>In fact, it is in mapping 3 where a clear and sharp difference is perceived.

The basis of this step is the cylinder kit of 49 mm in diameter, which raises the engine about 80cc. (140.0223) with the Polini elongated ratios (202.1424) mandatory for a result optimal.

The performance improves both in terms of maximum speed and acceleration, with a decisive sprint both at the start and when overtaking , and an increase of 50% of the maximum speed.

The result is a lively character that satisfies even the most demanding Vespa fans who want a vehicle at the same time. fashionable but at the same time powerful. Also with this mapping it is advisable to combine the Polini variator (241.737), the Polini silencer (190.0079) and the  Polini oversized air filter hose (223.0131).
