Royal Enfield 1990674 Left Hand Number Board (Black, ABS) — OEM Side Panel Number Board

Upgrade or replace the left side number plate cover on your Royal Enfield with the 1990674 Left Hand Number Board — a genuine OEM accessory built by RE’s GMA division. Made from durable ABS plastic with a matte black finish, this piece maintains factory aesthetics while offering durability. 

This LH number board mounts on the left side panel (where the original side cover lock sits) and is designed to fit seamlessly on Classic 350 / Classic 500 / Bullet 350 / Bullet 500 / Electra 350 / Trials 350 / Trials 500 models. 
Installation is quick — the RE instructions list a 10-minute fitting time. 

Being a genuine Royal Enfield part, it matches factory quality, fit, and finish more reliably than aftermarket clones. Replace cracked or faded number boards with this OEM piece to keep your bike’s look intact.

FAQs

Q1: Will this board completely replace the original side cover?
A1: No — this part replaces just the number board insert on the left side cover (i.e. where the side cover lock is). The rest of the side panel remains unchanged.

Q2: Does this include the lock or hardware?
A2: No — usually this board piece integrates with your existing side cover lock and hardware (per RE instructions). 

Q3: Can I install this in under 10 minutes?
A3: Yes — RE lists the fitting time as approximately 10 minutes. 

Q4: Will this part fit my J-Series (BS6) Classic or modern models?
A4: Not guaranteed — the published compatibility is for UCE / legacy models. Unless you verify fitment in your region, list only for models confirmed above.

Q5: Does it affect warranty or structural strength?
A5: No — it's a cosmetic / body accessory, so properly fitted, it should not affect warranty or structural integrity.
