Replacing the digital meter on your Royal Enfield Thunderbird can be done, but it may not be possible to directly transfer the kilometers shown on the old odometer to the new one. Digital odometers are typically designed to prevent tampering or manipulation for accurate mileage tracking.
When you install a new digital meter, it will likely start from zero kilometers. It is not recommended to try and set the kilometers from the old odometer onto the new one as it may involve tampering or manipulation of the device, which could be illegal in some jurisdictions.
If you're concerned about maintaining an accurate record of your motorcycle's mileage, it is best to keep a record of the original mileage from the old odometer before replacing it. You can note down the mileage and keep it as a reference, but the new odometer will still start from zero.
It's important to remember that tampering with or altering the mileage on a vehicle's odometer is generally illegal and unethical. Odometer readings are used for various purposes, including determining the value of a vehicle and its service history. It's best to ensure the mileage on your motorcycle is accurately recorded and maintained.
