Royal Enfield 888147 – Chain Adjuster Kit (RH & LH) – Thunderbird 350/500, Classic 350/500, Bullet 500, Continental GT 535 (UCE) – Genuine OEM

The Royal Enfield 888147 – Chain Adjuster Kit (TB 350 & 500CC) is the genuine OEM kit used on the swingarm of multiple UCE 350/500 models, including Thunderbird 350/500, Classic 350/500, Bullet 500 and Continental GT 535. Royal Enfield’s own price list describes this part as “CHAIN ADJUSTER KIT – TB 350 & 500CC”, confirming it as a factory part, not a generic aftermarket substitute.

Factory microfiche and model-specific parts catalogues show 888147 as the chain adjuster kit (RH & LH) in the Swing Arm Assembly for Thunderbird 350/500, Bullet EFI & Classic models, and various Classic 500 special editions (Gunmetal, Pegasus, Stealth Black, Redditch). It is also used on Continental GT 535 (Euro 3 & Euro 4) swingarm diagrams.

This kit typically includes both right- and left-hand chain adjuster blocks with the necessary hardware (as supplied from the factory), allowing precise rear wheel alignment and chain tension setting. A worn or bent adjuster can cause uneven chain wear, poor handling, and sprocket misalignment. Replacing it with a genuine 888147 kit restores accurate chain adjustment and keeps the rear wheel true in the swingarm, which directly improves ride quality and drivetrain life.

Ideal for overhauls, swingarm work, chain & sprocket replacement, or restoration of older UCE bikes, this kit is the correct OEM solution backed by Royal Enfield engineering, not a universal “jugaad” part.
