Understanding Chassis and Engine Numbers: Why They Matter

Every motorcycle is identified by its chassis number (also called VIN or frame number) and engine number. These are stamped by manufacturers and recorded in registration documents. They help authorities trace ownership, prevent theft, and ensure roadworthiness. Altering or removing them without approval from the registering authority can trigger severe consequences.

Under the Motor Vehicles Act, 1988, Section 52 explicitly prohibits such changes: any change to the engine or chassis number is deemed an alteration of the vehicle. Such alterations must be approved by the registering authority to be lawful.[
