New Delhi:Hero MotoCorp Ltd (HMCL), the world's largest two-wheeler manufacturer on Wednesday said it has sold 583,117 units of two-wheelers in May as against 569,876 in the same month last year. "Market demand was expectedly subdued in May, due to the heavy retail off-take that happened in April on account of the marriage season and regional festivals in different parts of the country during that month," the company said in a statement. The two-wheeler maker said a good monsoon after two consecutive years of sub-normal rains could lead to a change in sentiments in the rural markets, which may lead to a positive turn-around in the industry in the second half of this fiscal. The company in May forayed into the world of motorcycle rally racing, through a strategic alliance with Speedbrain GmbH, the German off-road racing specialist. The newly formed 'Hero MotoSports Team Rally' made its debut at the Merzouga Rally, a Dakar series race that recently concluded in Morocco.
