  the hero honda cbz was a motorcycle launched in early 1999 by hero honda motors, with an original honda 156.8 cc engine. the styling of the bike was a scaled version of the famous honda cb series. the over-square engine, that met euro1, was fed by a keihin slide type carburetor with accelerator pump for better pick-up. it makes use of a larger spring operated nozzle to provide a richer fuel air mixture into the engine for better acceleration. an air injection system injects fresh air into the exhaust port, to meet the emission norms. ==cbz== the model went unchanged more or less for five years. in 2004, a new variant called cbz* (star) featuring new graphics was introduced to boost sales. the bike did not feature any engine or performance upgrades. the only change was in its carburetor, it was changed from the sliding type carburetor to a conventional cv carburetor, which increased the fuel-efficiency but hampered the pick-up, the greatest feature of the bike. the bike was discontinued after 2005 september. the cbz was followed after a gap of two years by the cbz-xtreme which was a totally new product platform featuring a honda 149&nbsp;cc engine and five-speed gearbox.the introduction of tfps is done through this bike.  ==cbz xtreme== {{infobox motorcycle | name = cbz xtreme | image = | aka = | manufacturer = hero honda | parent_company = | predecessor = cbz | successor = | class = naked bike | engine =  | bore_stroke =  | power = | torque = | transmission = 5-speed, constant mesh | suspension = | brakes = front 240&nbsp;mm discrear 130&nbsp;mm drum | tyres = front 2.75x18 - 42prear 100/90x18 -56p | rake_trail = | wheelbase =  | length=  | width=  | height=  | dry_weight =  | wet_weight = | fuel_capacity = {{convert
