Selling of old two wheelers

Dear respected expert, Please guide me regarding selling of an old two wheeler motorcycle. The vehicle was purchased by me in the year of 2002 and have completed 15 years of service & its validity for running on road as per RTO rules. The same become serviceable and to be scrapped. So kindly intimate the proceedure for scrapping, whether I can sell it directly to the "Kabadiman" by taking an amount or there are any other legal complications to sell the vehicle. Somebody told me that the same may be sold executing a deed on non-judicial stamp paper to be signed by the purchase mentioning the details of the vehicle. Kindly intimate me accordingly Thanks in advance.
