Contact Set / Contact Breaker Points (Distributor Ignition) for Royal Enfield Bullet 350/500 – 140954 (CB Point Set)

Royal Enfield Part No. 140954 is the genuine Contact Set—also known as contact breaker points / CB point set / distributor points—used in contact-breaker (points) ignition systems on older Royal Enfield motorcycles. If your bike is hard to start, misfiring, losing spark under load, or the ignition timing keeps drifting, worn points are a common root cause.

This part is a service item in the distributor: it opens/closes the primary ignition circuit to generate spark at the correct timing. Using the correct points matters because point geometry, spring tension, and rubbing block quality directly affect dwell and timing stability.

Also searched as: “contact breaker point set 140954”, “CB point set”, “distributor contact set”, “points set Royal Enfield”.

Before you buy: this is ONLY for bikes that still use a distributor/points (contact breaker) ignition. If your motorcycle has CDI/TCI/electronic ignition (no points), this is not compatible—please verify by photo of your distributor/points plate before ordering.

FAQs 

Q1 (Fitment): How do I confirm 140954 fits my Royal Enfield?
Check if your bike has a distributor/points (contact breaker) assembly. If you can see a points plate and rubbing block under the distributor cover, 140954 is the correct contact set.

Q2 (Fitment): Will this work on Electra / Machismo / Thunderbird?
Not always. Some versions moved to CDI/TCI/electronic ignition. If your bike does not have mechanical points, do not order. Share a photo of the distributor area to confirm.

Q3 (Comparison): Genuine points vs aftermarket point set—what’s the difference?
The main difference is timing stability (spring tension, contact material, rubbing block wear). Poor-quality points can drift timing faster and cause misfire/hard-start issues.

Q4 (Installation): What should a mechanic do during installation?
Install the new contact set, then set the point gap and ignition timing as per your service manual. Replace/inspect the condenser if needed (often serviced together).

Q5 (Symptoms): What problems does a worn contact set cause?
Hard starting, weak spark, misfire, jerks under load, backfire, and frequent timing changes.

Q6 (Returns-prevention): What photo should I send to avoid ordering wrong?
Send a clear photo of your distributor/points plate (open cover) or your old points next to the new one. If your bike has CDI/TCI (no points), we’ll guide you to the correct ignition parts.
