Aviod to buy. Review on Bajaj Discover 135 DTS-i

My father has got this bike in 2011 for his use .someone ask my father that it is the best bike and my father took this bike but after few months of use it was creating sounds from chain set even from that time this bike is become a money eatter for my father also drive this bike lots of time when I dont have bike but I am not satisfied with this bike I donot like suspension system.even nthe bike's engingine making lot of voices after one and half year and after 50000kms run milege of this bike is 50-55 kmpl and dont think this bike can be the trustable bike so please avoid to buy this bike.instead of this go for pulsar 150dtsi which is most better than this in engine stability road grip and one of the trustable bike then this .i will not suggest to any one to uy this bike even my father sold it afterc use of 2 years because this bike is money eater for my father
