I have a Yamaha ss125 blue, which is 2.5 years old. Well serviced (completed 5 free + 2 paid) and 21K KM done. Recently I changed the chain sprocket as it got damaged and gave a sound while riding. I usually ride it between 50 KM/hr to 60 KM/hr. The bike is good, but I notice then handle bar shake issue while nearing 55KM/hr and with pillion its higher. I thought it might be because the damaged rear tire and more often punctured rear tube (because of my locality). I recently changed the rear tyre to MRF Zapper Q, even after that am feeling the same wobbling issues.
Can anyone pls suggest or help what will be the issue. This wobbling causes pain in the forearms while riding long distances. I do weekend trips of 100KM to 150KM often. I have raised this issue to the service center (both authorized and mechanic) but no one has solved my problem yet..!! P!s help..
