Bajaj pulsar
Faulty spare parts

I brought 2 engine oil seal looking at the originality of the product on the packet with Bajaj name. But just day passed by the seal proved to be faulty and the leakage starts again. I again went to my mechanic brought the original bajaj oil seal and the same problem again started. I am experiencing this with many other small spare parts with bajaj motors. The price as compared are quiet high but the quality is too bad and the parts dont last their expected time.

Is it so that bajaj delibrately keep their parts quality low. While even selling it on high prices.
