Honda — Defective piece

I purchased Activa Honda Dx Black-grey on 20.12.2009 from M/S Empire Honda, G. T. Road, Bathinda (Punjab)151001 with temporary number PB-03Q(T) 8637. We did not drive it much because we have also one more activa model2001-02 with us. When we drive it, it is turning one side while driving. My wife went to the showroom for complaint then they told that its NAKKA(Inner part) has been broken. How it can be when we did not drive it. There is a manufacturing defect in it but they won't agree. There may be an accident while driving due to its turning to one side while driving. Still we did not applied for the registration certificate (RC). Company must send its Engineer to check it and give OK certificate so that we can apply for RC. The dealer at Bathinda is not cooperating & their dealing is also very bad. They forced us to take Accessories Compulsory with the Activa. I want to know from the company whether it is compulsory to take accessories with it or not?
