Who it's perfect for

This is the right spare part if your Beverly, BV, MP3 or X10 350 has lost initial acceleration, jerks during acceleration or makes a metallic noise from the transmission crankcase: these are classic symptoms of ovalized rollers. It's also an item to put on the list when planning your transmission service, along with the belt. Workshop technicians order 8 for each vehicle.

Frequently asked questions

How many rollers are needed for the Beverly 350?
The variator of the 350 cc 4T 4V Piaggio uses 8 rollers. The code B014273 identifies a single roller, so for a complete replacement, you need to order quantity 8. The same applies to BV 350, MP3 350 Maxi Sport, and X10 350.

Is the price indicated for one roller or for the set?
The price is for a single roller. We chose to sell them individually because it corresponds to Piaggio's official spare part coding: this way you can order exactly the quantity you need, 8 for a complete change or fewer if you only need a few pieces.

How often should the variator rollers be changed?
It depends on use, but on maxi-scooters, they are checked along with the belt. When the rollers become ovalized, the variator no longer closes smoothly, and you lose initial acceleration and top speed. If you find ovalization or wear flats during the service, all eight should be replaced.

Can I install rollers of a different weight than 16 g?
Technically yes, but it changes the vehicle's behavior: lighter rollers increase the shifting speed (more initial acceleration, less top speed), heavier ones decrease it. 16 g is the value chosen by Piaggio for these models and is the recommended choice for road use.
