i purchased apache rtr 160 on 19/06/2010 from sk jain tvs,hisar road ,rohtak,haryana.there is a huge noise in the rear wheel on 22/06/2010.i went to the service center and they change the ball bearing set.then again there is same noise on 25/06/2010.again i went to the center, they open up the rear wheel 3 to 4 times changing chain or other ball bearing set.when i came home it again started making the same noise only after 5 km.drive.in 6 days timing from purchasing it went to the service center 2 times and they take 3-4 hours daily.now how many times a working person can go to the center when he purchased a new bike.i want my bike to be replaced.
