When a new model is introduced, manufacturers often aim to improve certain aspects such as performance, fuel efficiency, emissions compliance, and overall quality. However, it's important to note that changes made between different model years can vary, and it would be best to refer to the specifications and features provided by Bajaj for the exact changes made in the BS6 version of the Pulsar NS200.
That being said, manufacturers typically strive to maintain or enhance the quality of their products with each new iteration. It's worth noting that customer feedback and reviews can also be helpful in understanding the experiences of other owners with specific models.
If you are considering purchasing the Pulsar NS200 BS6 2020 model, I would recommend researching and comparing the features, specifications, and user reviews of both the 2016/2017 NS200 model and the BS6 version. This will give you a better understanding of any improvements or changes made by Bajaj for the newer model. Additionally, visiting authorized Bajaj dealerships or contacting them directly can provide you with more specific information regarding the differences between the two models and help you make an informed decision.
