The country's largest two-wheeler maker Hero MotoCorp on Wednesday reported a 4.75 per cent decline in total sales at 5,24,766 units in February.
The company had sold 5,50,992 units in February 2016, Hero MotoCorp said in a statement.
"Majority of Hero two-wheelers had already been made BS-IV compliant quite some time back and the company has fully transitioned to produce only BS-IV vehicles across the range from today," the company said.
It further added that with improvement in the currency situation and in the consumer sentiment, its volumes are gradually picking up.
