Hero Honda started its operations in 1984 as a joint venture between Hero Cycles (sometimes called Hero Group, not to be confused with the Hero Group food company of Switzerland) of India and Honda of Japan. In 2010, when Honda decided to move out of the joint venture, Hero Group bought the shares held by Honda. Subsequently, in August 2011 the company was renamed Hero MotoCorp with a new corporate identity.
In June 2012, Hero MotoCorp approved a proposal to merge the investment arm of its parent Hero Investment Pvt. Ltd. with the automaker. The decision comes 18 months after its split from Hero Honda. "Hero" is the brand name used by the Munjal brothers for their flagship company, Hero Cycles Ltd. A joint venture between the Hero Group and Honda Motor Company was established in 1984 as the Hero Honda Motors Limited at Dharuhera, India. Munjal family and Honda group both owned 26% stake in the Company.
During the 1980s, the company introduced motorcycles that were popular in India for their fuel economy and low cost. A popular advertising campaign based on the slogan 'Fill it – Shut it – Forget it' that emphasised the motorcycle's fuel efficiency helped the company grow at a double-digit pace since inception. In 2001, the company became the largest two-wheeler manufacturing company in India and globally. It maintains global industry leadership to date. The technology in the bikes of Hero Motocorp (earlier Hero Honda) for almost 26 years (1984–2010) has come from the Japanese counterpart Honda.
