I used honda shine 125 nearly 3 years on good .Really it’s very very very good bike I have ever seen.I have bought it in 2014 . Firstly it gave 60 kmpl . But now; I.e after 3 years it’s still giving 65 kmpl https://m.mouthshut.com/the rel="nofollow" target="_blank" >@the speed between 50-55 kmph. No complain in chain socket. No complain in sound . I think they are new users with a sudden pick up bike . Yes. Honda shine 125 gives SUDDEN PICK UP . If u r new rider then obviously your driving may cause these problems. Otherwise normal bike users can appreciate it . Honda shine is one of the best 125 cc bikes .
