Royal Enfield KAA00077/A – Counter Weight Kit (Chrome) for All New Classic 350 (Reborn) & Meteor 350 | Genuine OEM

If your handlebar feels buzzier than usual, or your bar-end weight is scratched, loose, or missing after a fall/traffic hit, the Royal Enfield KAA00077/A Counter Weight Kit (Chrome) is the correct OEM replacement to restore factory fit, finish, and riding feel. This is a genuine Royal Enfield “counter weight kit-chrome” part, designed to sit at the bar ends to add mass and help reduce handlebar vibrations during daily commuting and highway cruising. 

Unlike generic aftermarket bar-end weights (where threading/finish varies), this OEM kit is intended to match the original chrome look and installation geometry for the compatible models. 

Best use cases:

• Replacing damaged/oxidized bar-end weights

• Fixing looseness/rattling from worn bar-end hardware

• Restoring OEM chrome styling after handlebar/lever upgrades

• Preventing grip-end wear caused by missing counterweights

FAQs 

1. What is KAA00077/A used for?
   KAA00077/A is a Royal Enfield “Counter weight Kit – Chrome” used at the handlebar ends to add mass and help reduce handlebar vibrations while restoring OEM chrome styling.

2. Which Royal Enfield models does KAA00077/A fit?
   Confirmed compatibility is All New Classic 350 (Classic 350 Reborn/J-Series) and Meteor 350. If your model is not listed here, treat fitment as unconfirmed. 

3. Does this fit Classic 350 UCE / Classic 500 / Bullet UCE / Electra / Thunderbird / Hunter 350?
   ❌ Not confirmed for those models in the verified sources for this part number. To avoid wrong orders and returns, buy it only for the confirmed bikes listed in the compatibility table. 

4. Is this OEM or aftermarket? Why does it matter?
   This is described as a genuine Royal Enfield part. OEM matters because bar-end weights depend on correct threading/seat/length—universal weights often cause looseness, mismatch, or finish issues. 

5. I have bar-end mirrors / handguards installed—will this still work?
   Maybe. Many bar-end mirror and handguard systems replace or change the bar-end mounting stack. If your accessory uses its own expansion bolt or adapter, you may need accessory-specific hardware instead of the OEM counterweight kit. (Best practice: check your current bar-end mounting design before ordering.)

6. What’s the difference between KAA00077/A (Chrome) and KAA00076/A (Black)?
   Both appear as Royal Enfield counterweight kits, but KAA00077/A is Chrome and KAA00076/A is Black, allowing you to match your bike’s handlebar-end styling. 

7. My handlebar vibrates—will replacing counterweights solve it completely?
   Counterweights can improve comfort, but vibration can also come from engine tuning, worn grips, loose handlebar clamps, bent bars, or incorrect accessories. If vibration is sudden or severe, inspect mounting points first.

8. How do I confirm I’m ordering the correct part?
   Match KAA00077/A against your requirement (service bill, parts reference, or existing part). If unsure, message Under The Hood with your bike model + year + a clear photo of your current bar end.
