Aprilia 1B007787 Underseat Compartment Lid – SXR 50 and SXR 160 (2021-2025)

The Aprilia 1B007787 under-seat tray cover is the original panel for the under-seat compartment of the SXR: in the official catalog, it appears in the "Central bodywork" table, between the compartment lid and its gasket. It's the part that finishes and closes the compartment from the inside, keeping the shape clean when the seat is opened and protecting the inner part from contact with the helmet. It's also a component that gets damaged easily: it cracks around the screw holes, deforms with summer heat, and breaks when someone forces the seat shut with a full compartment. On a recent scooter, an under-seat compartment with a broken or missing tray cover is the first thing noticed when opening the seat, and during resale, it carries more weight than the cost of the replacement part.

Frequently asked questions

What is Aprilia part 1B007787?
It is the under-seat tray cover for the Aprilia SXR. In the official catalog, it appears as "Contre-porte" at position 7 of the "Central bodywork" table, between the compartment lid and the compartment gasket. It finishes and closes the compartment from the inside.

Which SXRs does it fit?
On the Aprilia SXR 50 4T 3V E5 HE New Comfort from 2021 to 2023 and the MY2025 version, and on the SXR 160 BSVI ABS from 2021 to 2023, including the 2023 4T 3V ABS version. It is the same code for both displacements.

Why does it break?
Almost always around the screw holes: the plastic is thin, and excessive tightening cracks it. Summer heat, which deforms it, and forcing the seat shut when the compartment is too full also contribute.

Is it difficult to replace?
No. Open the seat, unscrew the fixing screws, and replace the panel: there's no need to disassemble the external bodywork. The only caution is not to overtighten the screws on the new plastic.

Does it also include the gasket and screws?
No, it's the tray cover only. The compartment gasket, lid, hinges, and screws have dedicated Aprilia codes and must be reused or ordered separately: if the old one broke due to excessive tightening, it's advisable to also change the screws.
