Additional Documented Fitment

Current Indian genuine-parts retail references also list part 867045 for Thunderbird X 350 and Thunderbird X 500 applications. Because model-year and rear-body configurations can differ, Thunderbird X owners should compare the original subframe shape and mounting points before ordering.

Not Compatible With Unless Specifically Confirmed

• Thunderbird 350X / 500X without matching the original subframe first
• Meteor 350
• Classic 350 Reborn
• Hunter 350
• New Bullet 350 J-Series
• Himalayan or Scram models
• Interceptor or Continental GT 650
• Any motorcycle whose rear frame arrangement does not specify 867045 or 594125/B

Part-Number Replacement Note

Earlier Royal Enfield part number 594125/B is listed as the Thunderbird subframe and the current parts system points to 867045 as its replacement/alternate number.

If the motorcycle currently carries 594125/B in an older parts catalogue, part 867045 is the replacement number to check against the physical mounting arrangement.

Important Structural Fitment Note

This is a structural rear-frame component. Do not order solely by motorcycle name if the bike has been modified, converted, repaired after an accident or fitted with non-standard seats, backrests or rear bodywork.

Before ordering, inspect:

• Main-frame mounting points
• Seat and pillion-seat brackets
• Back-rest and luggage-carrier mounting locations
• Rear body and mudguard clearance
• Existing subframe shape
• Any previous welding or frame modification

Technical Details

When Replacement May Be Required

• Subframe is bent after a rear impact or fall
• Welded mounting points are cracked
• Severe corrosion has weakened the structure
• Seat or back-rest mounting points are distorted
• The original subframe has been cut or modified
• A restoration requires the factory rear-frame arrangement

If the motorcycle has suffered a significant accident, the main frame must also be inspected for alignment and cracking. Replacing the rear subframe alone does not correct a bent or damaged main chassis.

Installation Note

Installation should be carried out by a qualified Royal Enfield or motorcycle chassis technician.

• Support the motorcycle securely before dismantling the rear structure.
• Inspect the main-frame attachment points for cracking or distortion.
• Transfer only serviceable seats, handles, back-rest and carrier hardware.
• Replace damaged fasteners rather than reusing bent or stretched hardware.
• Align the subframe before fully tightening mounting bolts.
• Use the applicable workshop-manual torque specifications.
• Check seat latch operation and rear-body clearance after installation.
• Confirm that electrical wiring, rear-light harnesses and hoses are not pinched by the new frame.

Buyer-Focused FAQs

What is part 867045?
It is the black powder-coated rear seat subframe used on applicable Royal Enfield Thunderbird 350 and Thunderbird 500 motorcycles.

Is this the complete motorcycle frame?
No. It is the detachable rear seat/pillion subframe, not the main chassis.

Does 867045 replace 594125/B?
Yes. Current Royal Enfield parts information points the earlier 594125/B subframe to 867045.

Does it fit both Thunderbird 350 and Thunderbird 500?
Yes. The original Thunderbird 350/500 parts catalogue lists the same subframe application for both models.

Does it fit Thunderbird X 350 or 500?
Current Indian genuine-parts retail references list it for Thunderbird X models as well, but the original rear structure should be physically matched before ordering because rear-body configurations can differ.

Are the grab rails, backrest and carrier included?
No. They are separately catalogued components.

Are the mounting bolts included?
Do not assume so. Fasteners are separately catalogued unless physically supplied inside the genuine package.

Can this repair a bent main frame?
No. The main motorcycle chassis must be inspected and repaired separately if damaged.

Order Verification and Return Prevention

Before ordering, verify the motorcycle model, rear-frame configuration, mounting points, existing subframe shape and part number 867045 or earlier number 594125/B.

Structural frame components that have been installed, scratched, modified, welded, drilled, bent or damaged are not eligible for return due to incorrect model selection or installation errors.
