Royal Enfield Adaptor with PAV Connection for Classic 500 EFI / Bullet 500 EFI – 572304/A

Royal Enfield Adaptor with PAV Connection for Classic 500 EFI / Bullet 500 EFI – 572304/A

572304/A is a genuine Royal Enfield adaptor with PAV connection. Your product photos clearly show the factory pack label as ADAPTOR-WITH PAV CONNECTION, and multiple public fiche/dealer sources repeat the same exact description. This is the correct part to list as the PAV adaptor, and it should not be mixed with 571091/A, which is the flange / inlet manifold piece.

This part is commonly searched as PAV adaptor, EFI inlet adaptor, intake adaptor, throttle body adaptor, and Royal Enfield adaptor with PAV connection. Current source coverage most strongly supports Classic 500 EFI and Bullet 500 EFI. Some seller sources also mention Thunderbird 500, but the strongest direct support remains cleaner for Classic/Bullet 500 EFI, so Thunderbird 500 is kept unverified here.

This is the right type of part when the PAV-connected adaptor in the intake / emissions path is cracked, leaking, hardened, or damaged. Before you buy: confirm your motorcycle is a 500cc EFI UCE bike and compare the old adaptor’s shape and connector provision with your existing part.
