Restore the factory seal and clean look on the right-hand engine oil filler with the genuine Royal Enfield 570872 – Oil Filler Cap, Cover RH. This OE cap closes the RHS oil-filler opening on UCE engines and keeps dust, water and grime out of the crankcase area. Because it’s OEM, the inner lip, OD/ID and locking profile match the original, so it press-fits securely and won’t rattle loose like universal plugs.
Fitment is verified for Bullet 350 UCE (Kick/Electric Start), Bullet 500 UCE, Electra 350 UCE (ES) and Thunderbird Twinspark (TBTS)—all platforms that use this specific right-side filler cover. Multiple OE sources also note the running change to suffix “/C” on later production (570872/A → 570872/C), with function and fit retained. Order this listing when your old cap is missing, cracked or hardened; it’s a quick, inexpensive refresh that prevents contamination during washing or rain rides.
Supersession Note: Early cartons show 570872/A. Current supply commonly ships as 570872/C (same application).
