NEW #polini E-P3 MX

Faithful to its slogan, the company of Bergamo goes on with the development of the products dedicated to the e-bike world, and presents the evolution of the E-P3 electric motor. E-P3 MX is born, more powerful and performing than the previous one, it has been studied for the MTB and dedicated to the most exigent customers who look for more motor torque.

Thanks to the good job of research and development, #polini wanted to achieve the aim to have a motor for the off-road models, more resistant to external agents with 144mm central axle but without changing the overall dimensions and geometries in order to be installed on the frames already manufactured.

This leap forward gives the possibility to satisfy a market even more careful to the motor power and battery life.

The torque of the new E-P3 MX motor passes from 70Nm to 90Nm, increasing the motor power that the motor can exploit above all at low rpm.

POLINI KIT FOR VESPA 300 GTS – PIAGGIO BEVERLY EURO 3 AND 4: POWER EXPLOSION

With the help of the technology used for the Formula 1 engines, #polini Motori has designed a new cylinder kit that wants to be a point of reference for Piaggio 300 engines tuning.

Thanks to the special barrel made of steel with Nicasil coating and to the “HTR” ring (High Turbulence Ring) it has been possible to increase the bore to 77mm, bringing the displacement from 278 cm3 to 294 cm3: an incredible explosion of power for your scooter engine.

The cylinder kit can be installed without any modification to the crankcase and to the original head.
Exclusive detail in the scooter market is the “HTR” ring that above improving the squish effect, it allows a larger supporting surface of the head gasket, granting great reliability of this part.

The piston has a wider skirt to resist to the side shifting generated by the coil; the combustion chamber, machined from the piston top, has been designed to have the best compression ratio with wide squish lines that match to the original head. The CDI has two curves specific for the different tuning steps: the first is proper to be installed with #polini Hi-Speed, cylinder kit and original muffler; the second one with #polini Hi-Speed, cylinder kit and #polini muffler.

With the new kit the performance is tangible just from the first rpm and the engine is powerful at all the rpm.
The cylinder kit comes with plug and play CDI and the wirings to be connected to the original system without any modification.
