OEM Aprilia Accessory Polyester Belt - 607538M
An official Aprilia Accessory
Largest waist size possible is 49.5"
Smallest is aproximately 33", but the buckle is a screw type clasp, so the belt can be cut and shortened, if desired.
One thing to note about this belt is that the Aprilia Racing logo only appears once on the belt, just after the notched end.
