While the Dominar 400 and NS200 are both motorcycles produced by Bajaj Auto, it is difficult to provide a definitive answer without specific knowledge of the parts and their compatibility. However, in general, clutch wires are designed for specific models and variations, taking into account factors such as handlebar positioning and cable length requirements.
Given that you have converted your NS200 to flat bars, the clutch wire designed for the Dominar 400 may not be an exact fit for the NS200. The length and routing of the clutch wire could be different between the two models due to variations in frame design and handlebar positioning.
To ensure the proper functioning and safety of your motorcycle, it is recommended to use the clutch wire specifically designed for the NS200. You should consult with a professional mechanic or contact Bajaj Auto directly for accurate information and guidance on suitable replacement parts for your modified NS200. They will be able to provide you with the most reliable information based on their expertise and knowledge of the motorcycles' specifications.
