Guys I've recently bought Yamaha FZS 25 BS6 for Rs.1.82 lacs. When I'm riding my bike on super smooth tarmac road my bike front handlebar mildly bouncing like some gravel comes under my tyre. And this thing happening in a rhythm like every 1 second gap. Checked my tyre pressure puncture but everything is fine. The feeling is like something attached to my wheel. I've bought my bike on 4th may and ridden only 170km. What might be the reason guys? Tomorrow I'm visiting Yamaha service centre. I'm extremely upset about this issue.
