YEZDI 250 CC

ODE TO RISE AND FALL OF A ‘STAR LEGEND’

IDEAL JAWA (INDIA) LIMITED popularly known as JAWA started operations in the year 1960 with the main objective to manufacture motorcycles amount other things. The idea was to deliver to the consumers a product that defined value for money.
The logo ‘For Ever Bike For Ever value’ very aptly signifies the ideology behind the product. This motive remains unchanged to this day, even in the face of stiff competition.

JAWA started commercial production of motorcycles in the year 1961 in technical collaboration with JAWA LIMITED of erstwhile Czechoslovakia and during the years 1961 to 1985 put up a good performance and achieved good profitability levels. The peak capacity utilization was 85 % with 36,000 vehicles on a capacity of 42,000 vehicles per annum. The collaboration agreement with JAWA of Czechoslovakia which, among other this ensured continuous availability of technical knowledge from the said collaborator ended in 1968, by that time JAWA had established an in house expertise for achieving wholly indigenous manufacturing technology and also design of vehicles known under the brand name of “YEZDI”.

JAWA had established market and had brand loyalty in Southern, Western and Northern regions and till 1985-86, they were in the seller’s market. It was now that there was an aggressive entry into the domestic market by Japanese technology backed vehicles of 100 cc category which were more fuel efficient, with sophisticated design, and state-of-the-art technology. All these motorcycles although made the selling of YEZDI motorcycles a difficult proposition, JAWA however, withstood the competition and continued the production and sales of motorcycles with a niche market without losing the brand loyalty in most of the regions. This was achieved by two major features of YEZDI motorcycles, with are attributable to user friendly design, lower maintenance costs and attractive pricing. JAWA motorcycles are also sturdy and rugged which are particularly suitable for semi urban and rural users.
