Q. While riding I get vibrations, is there any problem?

The first put-off, before you even begin to ride aggressively, is the noticeable lack of refinement. There’s a buzz, almost a rattle, between 2-3000rpm emerging from the tank shrouds and the motor itself sounds unrefined at most revs except at the redline. This is particularly bothersome because, in reality, it’s quite a fast and tractable motor. It’s capable of getting up to thrilling speeds quickly - if not as quickly as the Z650 - and the proof is in the numbers. It goes from 0 to 60 kmph in 2.36 seconds and 0 to 100 kmph in 5.18 seconds -- quick, but just not as quick as the Z (0 to 100kmph in 4.48 seconds). In-gear acceleration is also very impressive, with the 650NK clocking 30-70 kmph in 3rd gear in just 3.71 seconds and 40-80kmph in 4th gear in 3.64 seconds. It feels fairly involved in the process of racking up speeds, too, but all along, you have kept longing for a sign of premiumness or refinement, neither of which arrives. Moreover, if you are facing such an issue, then we would suggest you get your bike checked at the nearest authorized service center as they would be the better people to assist you in this case by inspecting the bike.
