Royal Enfield Grommet (St. Motor Cover) for Bullet 350 UCE, Classic 350, Electra 350 & TBTS – 580286/A

Royal Enfield Grommet (St. Motor Cover) for Bullet 350 UCE, Classic 350, Electra 350 & TBTS – 580286/A

580286/A is a genuine Royal Enfield grommet for the starter motor cover / ST. motor cover. Public Royal Enfield fiche-style sources identify this part exactly as GROMMET (ST. MOTOR COVER), and dealer references tie it to older UCE-platform motorcycles including TBTS, Bullet 350 UCE (ES), Electra 350 UCE (ES), and Classic 350. This is a small but important rubber mounting/support piece used around the starter motor cover area, where correct cushioning and fitment matter more than buyers usually expect.

Buyers also search for this as starter motor cover grommet, starter cover rubber, Royal Enfield grommet rubber, motor cover mounting rubber, and UCE side cover rubber. Because this is a shared rubber hardware part, it is best sold by part number + function + old-part match, not by broad engine-family assumption alone.

Before you buy: match the old rubber piece and confirm your motorcycle is one of the supported UCE applications. This is the correct kind of part to replace when the original grommet is hardened, torn, missing, loose, or causing poor cover seating / vibration.
