Three-wheeler sales are reviving, and also exports. Providing a reason for companies like Bajaj Auto to cheer up, the reason for the revival is said to be the discontinuation of permits in Maharashtra, the requirement for new permits in Delhi, and the replacement of two-stroke three-wheelers with four-stroke equivalents in Bangalore. Claim industry sources that there is an incremental market of 1.5 to two-lakh three-wheelers. While the revival in exports is said to be gradual, the rise in domestic demand looks more heartening. Sources draw attention to the four per cent rise in Bajaj Auto three wheeler sales volumes in the second quarter of the current fiscal. This, they explain, marks the first positive volume growth year-on-year after a span of past few quarters. The three wheeler segment posted a 14 per cent growth in the second quarter of this fiscal.
