Genuine Royal Enfield Piston Ring Set STD (350cc) for Bullet / Electra / Machismo / Campus | 112052

Rebuild compression the right way with the Genuine Royal Enfield Piston Ring Set – Standard (STD), Part No. 112052. This is a set of 3 rings (compression + oil control) intended for 350cc engines in the older Bullet-family platforms, and it is commonly listed as “RING SET, STD” / “Piston ring set – Standard (Set of 3 Rings)”. 

If your bike has blue smoke, low compression, hard starting, excessive blow-by, or high oil consumption, worn rings are a prime suspect. Using a genuine-spec ring set matters because ring material and sizing directly affect seal, heat transfer, and cylinder life—generic rings often cause poor bedding-in and repeat smoke.

Before ordering: confirm your bore is still STD. If your cylinder has been rebored, you may need an oversize ring set (example listings show related oversize ring sets like 112053 (0.020") and 112054 (0.040") in the same part-number series). 

This listing is restricted to confirmed 350cc legacy models only (see Compatibility) to reduce wrong orders and returns.

FAQs 

Q1. What does “STD” mean in piston rings?
STD means standard bore size (not oversize). If your cylinder was rebored, you need the correct oversize rings. 

Q2. How many rings are included in 112052?
It’s commonly sold as a set of 3 rings (standard 350cc ring set). 

Q3. Will this fit UCE Classic 350 / J-Series Classic Reborn / Hunter / Meteor?
Not confirmed. This part number is marketed for legacy 350cc platforms (Bullet/Deluxe/Machismo/Campus/Electra 4S/5S).

Q4. What symptoms indicate I should replace rings?
Blue smoke, oil consumption, low compression, hard starting, blow-by, and loss of power are common indicators. (A bore inspection is still recommended.)

Q5. Do I need any additional parts during installation?
Recommended: top-end gasket set, cylinder honing (if needed), and piston/cylinder measurement to confirm STD vs oversize before ordering.
