The ensuing emission norms under Bharat Stage III for two wheelers forced the bike maker Royal Enfield to increase the prices for its ranges. Thus, the bikes will be designed with new engines and high efficiency, said the MD of Eicher Motors. The irony is the current price of Royal Enfield bikes-in various brands like Classic, Classic 500cc, Thunderbird, Machismo and Electra– is Rs1 lakh and the range of increase is not yet revealed. Of these, Classic 500 cc has the handicap of less production and the pending numbers-3000 to 4000 in the domestic market and 2000 for export market- may be cleared in another five months, said MD. So far 1000 units of Classic 500cc have been delivered since November 2009.
