Royal Enfield — chain sprockets are broken

Hi,

I bought my classic 350 9 months back and completed 8, 800 kms. Almost 16 teethes of chain sprocket are broken. I am highly unsatisfied. I was using a bajaj pulser prior to this and i used it for close to 8 yrs, covered 85, 000 kms. I had to change the chain sprocket only once. Re spares are of very bad quality.
When i checked with service center for a replacement, they said they would have replaced it if this has happened within 4, 000 kms. I didn't understand their logic. Why does company give 1 year or 10, 000 km warranty.
I request the company not to manufacture such defective, worst quality products. We pay the money you demand to purchase this bike and we wait for 6 to 7 months to get the delivery. Please don't disappoint the customers. Please don't spoil the name of this brand.
