The country's leading motorcycle maker, Bajaj Auto, is staring at a year-on-year decline of at least 10 per cent in revenue and profitability in the first quarter of FY18, that is April-June. The primary trigger for this weak performance is a 11 per cent drop in motorcycle sales volume for April-June quarter. The commercial vehicles business, primarily three-wheelers, saw an eight per cent drop in volume for the period.
