The sprocket size of a motorcycle can vary depending on the specific model, year, and any modifications made to the bike. Generally, the Pulsar 150 motorcycles are equipped with a front sprocket (countershaft sprocket) with 15 teeth and a rear sprocket (rear wheel sprocket) with 43 teeth. This combination provides a balance between acceleration and top speed.
Please note that the sprocket sizes can be modified by individual riders to suit their riding preferences. Therefore, it is always recommended to refer to the owner's manual or consult with an authorized Bajaj dealer to get the accurate and up-to-date information regarding the sprocket sizes for the specific Pulsar 150 UG5 model.
