Hero Karizma was a premium motorcycle manufactured by Hero Motocorp. It was first launched in May 2003 and was given a cosmetic upgrade Karizma R in 2007. In September 2009, it was supplemented by another variant Karizma ZMR. The production of this motorcycle stopped in 2019 due to poor sales.

Design

Karizma has been designed specifically for the Indian market.[3] The styling is inspired by Honda CBF600.[2] The instrument panel and the tank recesses are also designed keeping their functionality in mind.[2]

Engine

Karizma has the tried and tested, but slightly detuned version of 223 cc SOHC air-cooled engine[1] from the CRF230 series of enduro/MX/supermoto bikes that are sold in the United States and South American markets. It has a five-speed gearbox in place of the CRF's six-speed. The engine is an all-aluminium, undersquare engine (bore 65.5 mm or 2.58 in and stroke 66.2 mm or 2.61 in) running a compression ratio of 9:1. It features a Kehlin CV carburettor with a CCVI switch. The Karizma ZMR on the other hand is imbued with fuel injection.

Developments

The most exciting development in the Hero stable has been that of its collaboration with American racing bike manufacturer Erik Buell Racing. The new Karizma R and ZMR have been inspired by Eric Buell Racing's EBR 1190.[4] The American company had a substantial role in the design of the high end bikes coming from Hero.
