The maintenance cost of the Bajaj Pulsar 125 is not fixed and can vary based on several factors, including the condition of the vehicle, labour charges, and the cost of parts if any need to be replaced. For the initial services, the first three services are generally free, but you may need to pay for engine oil and any additional repairs. For example, in the first service, which is due at 500-750 km, you typically only pay for engine oil, with no other major changes required. Here is a rough estimate of what you might expect: - **First Service :** Free service, but you pay for engine oil. - **Subsequent Services:** Costs can range from Rs. 273 to Rs. 1,318 for each service, depending on the kilometers and months elapsed, as seen in similar models like the Pulsar 150. For precise costs, it is recommended to visit the nearest authorized Bajaj service center, as they can provide detailed estimates based on the bike's condition and specific needs.
