Unreveal Facts about Karizma ZMR that you didn’t know Hero Karizma ZMR is a performance bike from the stables of Hero MotoCorp. It is powered by an air-cooled 223cc single cylinder engine. Unlike the Hero Karizma R which uses a carburetor for fuelling, it uses Hondas Programmed Fuel Injection (PGM-Fi) technology. The improvements include a better throttle response, consistent mileage and there is no hassle of operating a regulator valve as in carbureted bikes. As with any bike that uses fuel-injection, the bike comes with a 16bit Electronic Control Unit and a bevy of sensors, such as a bank angle sensor, which cuts fuel supply to the engine if the bike exceeds a certain lean angle, and sensors to detect throttle position, intake air-temperature, engine oil temperature, crank position, oxygen level and manifold absolute pressure. Another technology used is Idle Air Control Valve (IACV), which automatically ensures idle stability in all altitudes. The Hero Karizma ZMR comes with equipped with large-diameter front and rear disc brakes, an aerodynamic full-body fairing, fully digital multi-functional speedo console, electric start, alloy wheels, tubeless tires, and LED tail-lamp as standard. Design and Ergonomics The Karizma ZMR is positioned as a sports tourer, and is equipped with an aerodynamic fullfairing to aid long-distance touring. The bike comes fitted with clip-on handlebars and moderately rear-set foot pegs that seat the rider bent slightly forward with the feet placed towards the rear, in a position that offers maximum control during spirited riding while not adversely affecting comfort during everyday usage. Engine and Gearbox The Hero Karizma ZMR is powered by a 223cc, air-cooled, fuel-injected, single cylinder engine that is tuned for low-end torque, developing 17.6 bhp @ 7000 rpm and 18.35 Nm torque right from 6000rpm. The high-torque nature of the engine also helps in cruising at high-speed. A 5-speed constant mesh gearbox is used to transfer power to the rear wheels. Suspension The Hero Karizma ZMR employs telescopic forks at the front and a pair of adjustable gascharged shock absorbers at the rear. Although they use hydraulic fluid, gas-charged shock
absorbers are better than pure-hydraulic units, as they improve the damping characteristics by reducing the build-up of air-bubbles in the fluid, helping to retain its optimum viscosity.
