Royal Enfield 1760061/E – Silver Trapezium Engine Guard (Kit 1990635) | OEM GMA Crash Bar for Classic 350/500 UCE, Bullet 350/500, Electra 350, Trials 350/500

The Royal Enfield Silver Trapezium Engine Guard is a genuine GMA/OEM accessory built for riders who want factory-fit protection without bulky aftermarket styling. This guard uses an angular “trapezium” profile that complements Classic/Bullet lines while adding a practical first layer of defense against low-speed falls, parking tips, and road-side nudges.

What makes this one worth choosing over generic crash guards is the OE-engineered fitment and corrosion resistance: Royal Enfield specifies a 32 mm stainless-steel tube construction, designed to resist corrosion even if the surface gets scratched, and finished with Royal Enfield branding on the uprights. 

Important for search + returns: Many boxes/catalogues use DMS Ordering Part No. 1760061/E, while the Royal Enfield accessory/kit reference commonly appears as 1990635—this listing is for the same Silver Trapezium Engine Guard.

FAQs 

1) Is 1760061/E the same as 1990635? Which one should I search?
Yes—1760061/E is commonly used as a catalogue/ordering reference (DMS), while 1990635 is the Royal Enfield accessory/kit reference shown on official GMA pages. If you searched either code, you’re looking for the Silver Trapezium Engine Guard. 

2) Will this fit my Classic 350 Reborn / J-Series (2021+) or Meteor 350?
No. The Reborn/J-Series and Meteor/Hunter use different chassis and dedicated trapezium guard part numbers (often KXA-series) and should not be mixed with UCE-fit guards. Ordering the wrong generation is a common reason for returns—match your bike platform first. 

3) Stainless steel vs mild steel guard—what’s the practical difference?
Royal Enfield specifies this Silver Trapezium as 32 mm stainless steel, chosen mainly for corrosion resistance (even if scratched) and long-term finish retention. Black trapezium guards for UCE may be steel with coatings, but they are a different part number and finish category. 

4) Does it require drilling/welding? How long does installation take?
It is intended as an OE accessory with a straightforward fitment approach, and Royal Enfield notes a typical ~20-minute fitting time on the accessory listing. Use correct tightening sequence and re-torque after a short ride. 

5) What should I verify before ordering (best practice)?
Confirm your bike is UCE platform (Classic/Bullet/Electra UCE, Trials) and not J-Series. If you are unsure, share your model + year + engine type and we’ll match the correct part number before dispatch to avoid mismatch. (UCE vs J-Series is the #1 confusion point in competitor listings.)
