Honda Motorcycle & Scooter India (HMSI) on Wednesday tied up with Shriram Automall India for selling pre-owned two-wheelers in the country. Through the tie-up, the partners aim to sell 3.5 lakh two wheeler units in the next three years. "At present the industry lacks an organised and reliable structure. Through this tie-up we aim to bridge this gap," HMSI Vice-President, Sales and Marketing YS Guleria told reporters here. Currently the contribution of pre-owned two-wheeler market is estimated to be around 15 per cent of overall sales, but the potential is immense, he added.
