The company had sold 12,382 units in June 2009, Suzuki Motorcycle India said in a statement.
"As promised, we have delivered quality products as well as customer satisfaction to our consumers. We will continue to keep up this growth momentum in coming months as well," Suzuki Motorcycle India Vice-President (Sales and Marketing) Atul Gupta said.
The subsidiary of the Japanese auto giant Suzuki Motor Corporation attributed robust growth last month on good response to its new motorcycle GS150R and its only scooter Access 125.
The two-wheeler maker had earlier this month launched its superbike GSX-R1000 at Rs 12.75 lakh (ex-showroom, Delhi) making it the costliest product from the company's stable in the country.
It had also launched another superbike Bandit1250S priced at Rs 8.5 lakh.
During the occasion, the company had said it is looking at a 40 per cent jump in sales this year. It had sold 1.88 lakh units in 2009-10 in the commuter segment.
Suzuki Motorcycle India also sells two other premium bikes in the country -- Hayabusa and Intruder -- costing Rs 12.5 lakh each.
