Modern Vespa

what's is your opinion? which is better variator?

Change the question to Polini or J.Costa.

Then it depends on the type of riding you do. For some performance gain and a higher top speed, go Polini. But for a more fun scooter to ride around town, the J.Costa is tops.

The Costa gives good results as it comes straight out of the box, but with the Polini you will be fiddling with different weight rollers to get what you want.

So how often do you use youir top speed?
