The 100 per cent subsidiary of Japan's Honda Motor Company has its plant at Manesar in Haryana, with a capacity of 1.5 million (15 lakh) units.
Rattan said the first plant has reached its 'maximum' capacity. The company is currently engaged in deep study on setting up a second plant in India.
A formal announcement on the second plant -- investment, location and things of that nature -- is expected by next month-end, he said.
At present, Honda products in India include Activa, Dio & Aviator in scooters, and Unicorn, Shine and CBF Stunner.
In 2008-09, HMSI sold 10.7 lakh (over one million) units in India.
"We are planning to achieve 12.5 lakh sales this fiscal year (2009-10) and cross the 15-lakh mark in 2010-11," Rattan said.
HMSI launched its first mass segment bike 'CB Twister' in Bangalore today. The 110 cc bike is equipped with a maintenance-free battery.
