The screws arrived quickly, no problems. Prices are somewhat high but I guess this comes from Honda. For me MSP is the best source for original parts.

Motorcycle Spare Parts only sell genuine spare parts made by each manufacturer. The Ring D39.5 part has been manufactured by Piaggio and is brand new and dispatched in its original packaging.
Diameter-specific rings are usually used as spacers or seating washers in suspension stacks, and AP8163102 is the ring with a 39.5 mm diameter referenced across multiple Moto Guzzi and Aprilia applications, including Pegaso 650 variants. It replaces earlier superseded numbers and is intended to preserve the original spacing and contact area in the specified assembly.
Correct function depends on being installed in the exact position shown in the parts diagram, since ring placement often controls bearing preload or bracket spacing. If the ring shows cupping or grooves, inspect the mating face for burrs that can cut into the new ring under clamp load.
