The bike was launched to fill the gap between 100cc and 150cc. Instead of launching a 125cc motorcycle, Hero Honda launched something powerful yet fuel efficient. T This Bike equipped with Keihin Conventional CV Carburetor and Complies (BS3) emission norms Bharat stage emission standards. The concept of Hero Honda in this motorcycle is it should be more powerful than 125cc motorcycles and more Fuel efficient than 150cc Motorcycles. The fairing of the bike was also scaled from the Hero Honda CBZ, However, the manufacturer failed to sell the expected number of units so the company revised and updated a facelift model in 2004 by changing conventional round headlamp design to the CBZ fairing. Despite this, it failed to sell the expected number of units and the bike was discontinued in 2005. It failed due to its price, which was costlier than its competitors bikes at that time. After this failure, Hero Honda updated the Ambition as an all new Hero Honda Achiever which shared only part of the side and tail panels set with same CBZ Xtreme Engine and Honda Unicorn engine.
