I'm sorry, but there seems to be a misunderstanding in your question. The Kawasaki Rouser and Kawasaki Pulsar are actually two different motorcycles produced by different manufacturers.
The Kawasaki Rouser is a series of motorcycles manufactured by Kawasaki Motors in collaboration with Bajaj Auto, an Indian motorcycle manufacturer. These motorcycles are primarily designed for emerging markets like Latin America and the Philippines. The Rouser series includes various models, such as the Rouser 135, Rouser 180, and Rouser 200.
On the other hand, the Kawasaki Pulsar is a series of motorcycles manufactured by Bajaj Auto, an Indian company. The Pulsar series has gained popularity in India and other countries for their performance-oriented design and features. Bajaj Auto is the sole manufacturer of Pulsar motorcycles, and they offer different models like the Pulsar 150, Pulsar 180, and Pulsar 220.
To summarize, the main difference is that the Kawasaki Rouser is a collaboration between Kawasaki Motors and Bajaj Auto, while the Kawasaki Pulsar is solely manufactured by Bajaj Auto. Additionally, they are targeted at different markets and have distinct model lineups.
