Do I need RTO approval (Form 22C) before modifying my motorcycle’s engine or chassis?

Any changes to essential characteristics (engine, chassis, dimensions, fuel system, weight) require prior RTO approval via Form 22C under CMVR Rule 47A. Approval is automatically granted if the RTO does not respond within 7 days.

What is Form 22G, and who issues it?

Form 22G is a compliance certificate from the workshop/OEM under CMVR Rule 112A, confirming that modifications meet safety, emission, and noise standards. Only authorised dealers or state-approved workshops can issue this form.

When must I file Form 22E to update my RC after modifications?

File Form 22E within 14 days of the date on Form 22G to update your Registration Certificate. Late filing can lead to penalties and vehicle seizure.

Are cosmetic changes like repainting exempt from RTO notification?

No colour change or wrap that alters dimensions requires advance notice via Form 22C and post-modification notification via Form 22E under CMVR Rules 47A/47B. Insurers must also be notified.

Can I fit an aftermarket exhaust or remove the silencer baffle without approval?

No, removing the silencer is illegal under CMVR Rule 232. All exhaust modifications require Form 22C, then Form 22G, followed by Form 22E, and must comply with noise/emission standards.

Should I inform my insurer about minor modifications like decals or seat changes?

Yes, all modifications, even minor ones, must be reported to your insurer to maintain coverage under Section 52(3) of the Motor Vehicles Act.

Are LED or HID headlamp conversions allowed, and what paperwork is needed?

Yes, but changes in lamp colour, position, or intensity are considered alterations under CMVR Rule 47A. Obtain Form 22C approval and file Form 22E afterwards. If the change affects brightness or beam pattern beyond OEM specs, Form 22G may also be required.

What are the rules for changing a motorcycle’s tyre size or suspension height?

Modifications affecting track width, ground clearance, or tyre clearance are considered alterations under CMVR Rule 47A. Follow the Form 22C → Form 22G → Form 22E process, and ensure tyres meet the specifications in your RC (Rule 95).

What indirect-vision devices will be mandatory on new motorcycles starting January 2025?

Starting 15 January 2025, all motorcycles manufactured must have a rear-view mirror or an “indirect-vision device” compliant with AIS-001 and AIS-002 standards.

Who can issue Form 22G?

Only OEMs, authorised dealers, or state-approved workshops can issue Form 22G under CMVR Rule 112A. Unauthorised garages cannot issue this certificate, making your modification invalid if the form is not provided.
