The company also said it expects to sell 10 lakh units of the Pulsar range of bikes in 2010, on the back of the yet-to-be launched bike.
"The all new sub-150cc Pulsar will be launched on December 9, 2009... The brand task now is to invest in category creation, thereby increasing the size of the sports segment," Bajaj Auto said in a statement.
The company said the 'sub-150cc Pulsar' will sport a new design and a power train. It, however, did not divulge the expected price of the new Pulsar.
The company already has three versions under the Pulsar series with 150cc, 180cc and 220cc engines.
"With this new bike, Pulsar is expected to touch the one million mark in 2010," the company said.
Bajaj Auto further said it has witnessed 80 per cent jump in sales of the Pulsar series over the last six months.
"In the second quarter of 2009-10, average sales (of Pulsar range) were 45,000 units per month as compared to average sales of 25,000 units per month in the second half of 2008-09 and have reached an overall share of 50 per cent in the sports segment," it said.
