Vespa LX / Sprint / Primavera 150 3V Polini Hi-speed control 241.710

POLINI MAXI HI SPEED FOR VESPA 125/150 4T 3V PIAGGIO ENGINES:

FUTURE PRESENT

Exalting acceleration and never-ending engine progression with the new Polini

maxi Hi Speed Variator studied for the futuristic Vespa 946 and for all the Vespa

125/150 4Stroke A/C Piaggio engines.

The characteristic is the already tested new lubricating system applied to all the

new productions.

But many are the technical features that mark out this new Maxi Hi Speed:

The rollers sliding surfaces have sustained a new polishing treatment to

improve the sliding.

Piston pin made of chromed nickel with the lowest friction coefficient: it features

the DLC carbon treatment for racing and aircraft applications dedicated to the

sliding and high wear components.

It has a big internal pocket that contains the grease, inside of which there is a

special spring that allows a constant grease distribution on the pin even during

the hardest conditions of use.

Thanks to this new technology the performance is constant and, compared to

the previous models, it isn’t necessary anymore to modify the rollers’ calibration

to find the best engine efficiency.

It is available with compression spring which is 7% harder than the original one

increasing the engine revolution rate when starting.

The rollers have a coating made of a new mixture of nylon and aramidic fibers.

This combines to give the best performance and less servicing costs thanks to

these particular features that have also improved the bush and pin lubrication,

while the rollers material allows for a better wear resistance.
