It is generally not recommended to swap the chain sprocket of one bike model onto another, especially if the models have different engine capacities or gear ratios. The Bajaj Pulsar 180 UG4 and Pulsar 220F have different engine configurations and power outputs. Therefore, the sprocket sizes and gear ratios are likely to be specifically designed for optimal performance and compatibility with their respective engines.
The Pulsar 180 UG4 comes with a stock chain sprocket size of 14/39, while the Pulsar 220F has a different stock sprocket size. Altering the sprocket size can impact the bike's overall performance, including acceleration, top speed, and fuel efficiency.
If you are considering modifying the sprocket setup on your Pulsar 220F, it is recommended to consult with a professional mechanic or a Bajaj authorized service center. They can provide expert advice and recommend suitable sprocket configurations that are compatible with your bike's engine and intended usage.
