CBZ

The bike was launched as Hero Honda CBZ in India. It was Powered by an Original Honda 156.6cc.The engine was based on Honda CRF 150F and it came equipped with TPFC. The term TPFC Means Transient Power Fuel Control system. This system uses a constant-choke carburetor. This Carburetor Play a major role by increasing the speed of the without any Power lag and Vibration jerks. The throttle valve inside the Carburetor creates the vacuum which operates a diaphragm pump, Which helps to controls the air-fuel ratio inside the engine through a tapered jet. Hero Honda CBZ is first and last bike to get TPFC Technology which gives a reasonable amount of boost by sending additional fuel into the engine when the throttle is opened. The model went unchanged more or less for five years. In 2004, a new variant called CBZ* (star) was launched with revised graphics and addition of self start, but it does not inspire CBZ enthusiastic which bike due to over enthusiastic use of graphics and significantly higher price compared to its competitors. The bike was discontinued after September 2005. The CBZ was followed after a gap of two years by the CBZ-Xtreme, which shared no parts with the CBZ, and had a 149cc engine and five-speed gearbox.

However, this increases the emission levels and TPFC Accidentally waste some amount of fuel, Because, the accelerator pump inject some extra amount fuel when the rider applies sudden throttle compensate for lean air-fuel mixture which it generates. Hence, TPFC was consequently discontinued. Later, the
