t was India's first performance motorcycle when it was introduced in 1999. Hero Honda created the CBZ as one of its models. CBZ was the first motorcycle to be marketed as being powerful. For the vast majority of Indians, motorcycles were a cheap and practical method to get from one area to another. Hero Honda CBZ launched the sports bike revolution in India, which was later challenged by Bajaj Pulsar. In addition, Hero Honda CBZ launched in India much earlier than expected. It had to contend with the well-liked, fuel-efficient 100cc commuter motorcycles. But in 2005, the model was dropped along with the alliance with Honda, and then CBZ Xtreme. Later, Hero MotoCorp changed the name to "Xtreme," which lacks the added CBZ flavour. The 156.8cc, 4-stroke, single cylinder, SOHC original Honda engine—a shortened version of the illustrious CB series—powered the Hero Honda CBZ. It had an accelerator pump for better pickup and was an oversquare engine that complied with Euro1 requirements. The Keihin slide type carburettor utilised in the CBZ has a larger spring actuated nozzle than other carburetors we have seen, which allows it to deliver a richer air-fuel mixture into the combustion chamber and increase power output. The engine produced a maximum of 12.5 horsepower at 8000 rpm and a maximum of 12.4 Nm at 6500 rpm when connected to a 5-speed constant mesh gearbox. It was the first 4-stroke motorcycle in India with a 5-speed transmission. This motorcycle was among the fastest at the time with a top speed of 115 kmph. Additionally, it has a 5 second 0 to 60 km/h acceleration.
