Sir register a police complaint for same and intimate the RTO where vehicle was registered, since RC is not transferred in case if any accident you can be made accountable.

See you have to file complaint for same.

Dear Sir,

Ask that person to file an FIR about lost documents. Use the FIR to reapply for all the documents. When the new documents are received, get a letter of sale and transfer to your name. Then go to RTO office to transfer the bike in your name.

- As per the Supreme Court Judgment, if you sold your vehicle and failed to transfer the ownership through legal way, then you will remain the owner of the vehicle, and further you will be responsible for any untoward incident and accident by the buyer. 

- As per the Indian Motor Vehicle, the transferor (seller) has to inform the Regional Transport Offices (RTO) within 14 days of the transfer of ownership. 

- Further , this Act also instructs the transferee (buyer) to inform the RTO about the change in vehicle ownership and produce all the required documents within 30 days of the transfer.

- You should first lodged your complaint with the police station after narrating all the facts and submit all the documents you have in your support.

- Further, also inform the RTO in written, after enclosing the said police complaint receiving copy , and thereby  request the official to change the ownership.

Send legal notice to company to which it was exchanged to forth with stop plying bike on road till RC not transfer. And any liability arise due to non transfer of RC, accident claim compensation without insurance and use of bike for any illegal act - Company only shall be liable.
