Royal Enfield Bullet 350 UCE Black Frame Assembly RAF00473/D

Restore a compatible UCE-generation Royal Enfield Bullet 350 with genuine Royal Enfield RAF00473/D. Royal Enfield identifies this structural replacement as Frame Assy – VB51 Black; specialist parts sellers catalogue it as the complete black frame for Bullet 350 BS3–BS4 applications.

Critical fitment and legal check: This is a model- and configuration-specific main frame, not a universal Bullet frame. Before ordering, have a Royal Enfield dealer or qualified frame specialist confirm RAF00473/D against the motorcycle VIN/chassis record, engine number, brake/ABS configuration and market. Also confirm the replacement-frame documentation, identification-marking and registration process required by the local transport authority.

Related Frame References

When Replacement May Be Required

• Accident damage has bent or distorted the frame
• A qualified inspection identifies a crack or failed weld
• Steering-head, engine-mount or suspension-pivot alignment is outside specification
• Severe corrosion has compromised structural integrity
• The original frame has been declared unsafe or non-repairable by a qualified professional

Do not replace a main frame based only on visual suspicion. Alignment, weld integrity and mounting geometry should be inspected by a trained motorcycle chassis professional.

Technical Details

Pre-Purchase Checklist

1. Confirm the full required part number is RAF00473/D, including the /D suffix.
2. Confirm the motorcycle is a UCE-generation Bullet 350, not the J-series model.
3. Provide the VIN/chassis number and engine number to an authorised Royal Enfield parts counter.
4. Confirm drum/disc brake and ABS/non-ABS configuration.
5. Compare every visible mounting bracket and pivot location with the original frame.
6. Confirm which loose bearings, races, bushes, fasteners and mounts must be ordered separately.
7. Check whether the transport authority requires prior approval, invoice wording, inspection, stamping or dealer documentation.
8. Confirm that your workshop is qualified and equipped for a full motorcycle rebuild and alignment check.

Installation Note

• Main-frame replacement requires complete motorcycle disassembly and should be performed only by a qualified Royal Enfield technician or experienced motorcycle chassis specialist.
• Support the motorcycle and engine safely before removing any structural fastener.
• Inspect the steering races, swingarm bearings/bushes, engine mounts, suspension mounts and all transferred hardware.
• Replace damaged, corroded, stretched or one-time-use fasteners as specified by the workshop manual.
• Route wiring, hoses and control cables exactly as specified; incorrect routing can cause abrasion, steering restriction or heat damage.
• Use the model-specific tightening sequence and torque values.
• After assembly, verify wheel alignment, steering movement, brake operation, cable free play and suspension travel before road use.
• Complete all legally required chassis identification, inspection, insurance and registration updates before using the motorcycle on public roads.

Important Return-Prevention Note

Motorcycle frames can appear nearly identical while differing in brake-system brackets, ABS provisions, engine mounts, tabs, stand mounts and documentation status. Order RAF00473/D only after VIN-level confirmation.

Record one continuous unboxing video showing the sealed parcel, shipping label, Royal Enfield label, full frame and every mounting area. Report a wrong, missing or transit-damaged item immediately with the video and original packaging.

Frequently Asked Questions

1. What is RAF00473/D?

It is a genuine Royal Enfield black main frame assembly identified by the factory description Frame Assy – VB51 Black.

2. Which motorcycle is it for?

It is catalogued for UCE-generation Royal Enfield Bullet 350 BS3–BS4 applications, subject to exact configuration confirmation.

3. Does it fit the new Bullet 350 J-series?

No. The J-series Bullet uses a different chassis platform and part references.

4. Does it fit every BS3 or BS4 Bullet 350?

Do not assume so. Brake, ABS, ES and market specifications can require a different frame number.

5. Can I order using the model year only?

No. Confirm the VIN catalogue, full original part reference and chassis configuration.

6. Is this the full rolling chassis?

No. This listing is for the welded main frame assembly, not a rolling chassis.

7. Is the swingarm included?

No. The swingarm and its spindle/bearings are separate parts.

8. Are steering bearings included?

Do not assume they are included. Order races, bearings and seals separately if required.

9. Are engine-mounting bolts included?

No loose mounting hardware is included unless explicitly shown and stated on the invoice.

10. Is the frame black?

Yes. Royal Enfield describes RAF00473/D as VB51 Black.

11. Is RAF00473 the same as RAF00473/D?

It is a related reference with the same description, but suffix revisions must be confirmed through a VIN-specific Royal Enfield catalogue.

12. Is 867073/A the same part?

It is an earlier VB51 frame reference. Do not treat it as an automatic supersession without dealer confirmation.

13. Does it fit Bullet 500?

No Bullet 500 compatibility is claimed for this listing unless Royal Enfield confirms RAF00473/D for the exact VIN.

14. Does it fit Classic 350 or Classic 500?

No compatibility is claimed. Those motorcycles may use visually similar but differently referenced frames.

15. Can a bent frame be repaired instead?

Only a qualified motorcycle chassis specialist can determine whether repair is safe and legally permitted.

16. Will the frame arrive with a chassis number?

No there will be no number but we will provide GST BILL

17. Can I stamp the chassis number myself?

Do not alter or stamp the frame until the authorised dealer and local transport authority provide the legally correct procedure.

18. Who should install it?

A qualified Royal Enfield technician or experienced motorcycle chassis specialist should perform the rebuild.

19. What should be checked after installation?

Verify alignment, steering, suspension, brakes, wiring/hoses, torque settings and all required legal documentation.

20. What should I record during delivery?

Make a continuous unboxing video showing the sealed parcel, label, complete frame and all mounting points.
