The Bajaj Pulsar 200NS and KTM motorcycles are separate brands, each with their own distinct models and components. Therefore, it is unlikely that the gear lever from a Bajaj Pulsar 200NS would be directly compatible with a KTM motorcycle.
While it's challenging to provide precise information without knowing the specific KTM model you are referring to, it's important to note that different motorcycle brands often have unique designs and specifications for their components. Gear levers, in particular, can vary in terms of length, shape, mounting mechanism, and compatibility with the gearbox of a particular motorcycle model.
To ensure a proper fit and functionality, it is recommended to use gear levers specifically designed for your KTM motorcycle model. You may consider reaching out to authorized KTM dealers or motorcycle parts specialists to inquire about compatible gear levers for your specific KTM model.
