Piaggio 83025R Variator Drive Belt – Beverly 350, BV 350, MP3 350 and X10 350 (2012-2021)

The Piaggio 83025R drive belt is the CVT variator belt for the 350 4T 4V maxi-scooters of the Piaggio Group: Beverly 350 and Beverly ST 350, BV 350 and BV 350 ST, MP3 350 Maxi Sport and X10 350. It is the component that transmits all the engine's torque from the variator to the clutch: it wears out over miles and is part of scheduled maintenance, not a replacement for a breakdown. On a 350 used for highways and ring roads, the belt works much harder than on a 125. Original Piaggio, available for immediate delivery from Moon Bike S.r.l. — Cercola (NA).

✓ Strengths

• Original Piaggio part number 83025R – the same component installed in production, not an equivalent
• One code for all 350 4V models – Beverly, BV, MP3 Maxi Sport, and X10
• Sized for the 350's torque – it's not a universal belt adapted for use
• Restores original acceleration and pickup – a worn belt thins out and reduces initial thrust
• Safety and performance replacement part – a belt that breaks while riding will leave the vehicle stranded
• New product, never installed · shipped from Italy

Technical specifications

Compatibility

Compatibility source: official Piaggio spare parts catalog (B2B), EMEA, APAC, and NAFTA markets. If your scooter is not listed, or if you are unsure of the version, send us the VIN, and we will confirm exact compatibility before you order.

Recommended products

• Original variator rollers – to be checked and replaced along with the belt
• Variator sliders – wear out along with the rollers
• Clutch and clutch springs – take advantage of the open casing to check their condition
• Rear hub oil – the most economical fluid change to do during the same service

Who is it perfect for?

This is the right replacement part for those who use a Beverly 350, BV 350, MP3 350, or X10 350 for serious mileage — commuting, ring roads, travel — and have noticed that the scooter no longer pulls like it used to: it starts slowly, slips on inclines or with a passenger, the engine revs up without the speed following. On these 350s, the belt is stressed much more than on a 125 and reaches the end of its life sooner than expected. It is also the spare part that workshops keep on the shelf, because a single code covers the entire 350 4V family of the Piaggio Group.

Frequently Asked Questions

How do I know if the belt needs changing?
Signs include: weak acceleration, slipping on inclines or with a passenger, engine revving without gaining speed, vibrations or noise from the transmission casing. A removed belt will show shiny flanks, transverse cracks, and reduced width compared to a new one.

How often should it be replaced?
It is scheduled maintenance, and the interval is indicated in your scooter's manual. On a 350 used for commuting and highways, the belt works hard: it's not advisable to stretch it beyond the recommended interval, because if it fails while riding, it will leave you stranded and can damage the casing.

Is it suitable for my scooter?
It is intended for Beverly 350 and Beverly ST 350, BV 350 and BV 350 ST, MP3 350 Maxi Sport, and X10 350 in the versions and years listed in the table. If you are unsure, send us your VIN: verification is free.

Do I also need to change the rollers?
We recommend it. Rollers and sliders wear out along with the belt and are in the same casing: changing them in the same service costs little more in parts and nothing in labor, and will make your scooter feel like new.

Is an aftermarket belt better?
On a maxi-scooter's transmission, the belt transmits all the engine's torque: the quality of the compound and reinforcements makes a difference in durability and performance. This is the original Piaggio 83025R code, new and never installed.

Can I install it myself?
You need to remove the transmission cover and have specific tools to lock the pulleys. If you don't have experience and the right tools, it's best to have it installed at a workshop.

How long does it take to arrive?
The item is available in stock and shipped from Italy. You will receive the tracking code as soon as the package departs.
