The list is taken from the official Piaggio spare parts catalog (B2B area). The code is found in the historical catalog for the X9 500 (frame ZAPM27000), Engine group, plate T12 "Drive pulley", position 6. Before ordering, verify code 827826 and your vehicle's frame number.

Who it is perfect for

This belt is for those who keep a first-series X9 500 or Atlantic 500 on the road and face the classic problem of these vehicles: the original belt is no longer available at reasonable prices. It is the right spare part for those who do not want to settle for an aftermarket product with approximate dimensions on a variator that, if it slips, also damages the pulleys and the clutch bell.

Frequently Asked Questions

Which scooters does this belt fit?
The first-series Piaggio X9 500 (frame ZAPM27000) and the 2001-2004 Aprilia Atlantic 500 4T. These are the two maxi-scooters that share the same variator group. On subsequent versions of the X9, the catalog specifies a different, longer belt, so the frame must always be checked.

What are its exact dimensions?
1009 mm in length and 26.3 mm in width, with a trapezoidal section and transverse teeth on the inner side. These are the original equipment dimensions: the belt sits in the grooves of the original pulleys and maintains the gear ratio intended by the manufacturer, without affecting either acceleration or top speed.

My catalog shows AP8560070: is it the same part?
Yes. AP8560070 is the code by which Aprilia identified this belt, and Piaggio unified it under its own code 827826 when it merged the two brands' catalogs. It is the same spare part: if your mechanic or manual indicates AP8560070, this is the part to order today.

Can I use the 832738 instead of this one?
No. The 832738 is the belt for subsequent versions and is significantly longer: if installed on a first-series variator, it works outside the useful stroke of the pulleys, resulting in sluggish starts and abnormal wear. They are two distinct parts and remain so in the catalog: check the frame and order the correct one.

How often should the variator belt be changed?
On these 500cc models, the manufacturer indicates checking during service intervals and replacing based on condition. In practice, it should be changed when it falls below the minimum width, when the internal teeth are cracked, or when the scooter jerks during takeoff. A neglected belt can break and damage the casing and pulleys.

Why is the list price so high compared to the sale price?
Because it is a code for a model that has been out of production for years, with very low turnover: the manufacturer's list price has remained stagnant at a value no longer used. We sell it at the current market price for original spare parts. Once the current stock is gone, this code will no longer be replenished.
