Bajaj Dominar 400 & 250 Service Schedule, KM List & Cost

The Bajaj Dominar 400 is the largest bike in Bajaj’s range and needs servicing on different assumptions from the Pulsars it shares showrooms with. It holds nearly twice the engine oil of a commuter Pulsar, runs a liquid-cooled engine with coolant as a real maintenance item, and works its oil considerably harder.

Quick answer: 1st service 500–750 km · 2nd 5,000 km · 3rd 10,000 km · 4th 15,000 km · then every 5,000 km. Engine oil ~1.7 litres (2019+), 10W-50 semi-synthetic, coolant ~1 litre.

Dominar Service Schedule — KM List

Service	KM Milestone	Time	Cost
1st Service	500 – 750 km	1 month	Free (Bajaj warranty)
2nd Service	5,000 km	6 months	Free (Bajaj warranty)
3rd Service	10,000 km	12 months	Paid — from ₹1,199
4th Service	15,000 km	18 months	Paid — from ₹1,199
5th Service	20,000 km	24 months	Paid — from ₹1,199
Subsequent	Every 5,000 km	Every 6 months	Paid

The km milestones match the rest of the Bajaj range. What differs is the work at each service and the cost, driven by oil quantity and the cooling system.

Add coolant level and condition at every service, with proper assessment around every 10,000 km.

Engine Oil — Capacity Changed Across Generations

Specification	Dominar 400
Oil capacity (2019 onward)	~1.7 L
Oil capacity (pre-2019)	~1.5 L
Grade	10W-50, API SL, semi-synthetic
Rating	JASO MA2
Coolant capacity	~1.0 L (Bajaj Koolex)

This is one of the models where model year genuinely matters. Bajaj revised the Dominar 400 significantly in 2019, and oil capacity went up with it. A 2017 Dominar and a 2021 Dominar do not take the same quantity.

If you are unsure which you have, check the owner’s manual for your registration year, or ask our mechanic to confirm before filling. Filling a pre-2019 engine with 1.7 litres overfills it by 200 ml.

JASO MA2 is not optional. The wet clutch runs in engine oil, and friction modifiers in car oils cause clutch slip — revs climbing without matching acceleration, most obvious under hard acceleration in higher gears.

Oil change interval

Riding pattern	Recommended
Frequent touring / sustained high speed	Every 4,000 km
Daily city commuting	Every 4,000 – 4,500 km
Mixed use	Every 5,000 km
Low usage	At least once every 12 months

A liquid-cooled 373cc engine in Pune traffic is in the hardest condition it will encounter. The radiator needs airflow; stationary in a jam there is none, so the fan carries the load and the engine soaks at high oil temperature while the odometer barely moves.

Coolant — A Real Service Item

Coolant is not fill-and-forget. Its corrosion inhibitors deplete over time, and once they are gone the fluid still circulates and still looks fine while the aluminium internals corrode and radiator efficiency falls.

Early symptoms are subtle: the fan running more than it used to, the temperature reading sitting higher in traffic, slightly reduced performance on hot days.

• Check the level cold, on level ground, at every service.
• Bajaj specifies Koolex. Use it or an equivalent to the same specification.
• Never top up with plain water except as a roadside emergency — water corrodes and boils too readily.
• Never use car coolant — many are silicate-based and aggressive toward motorcycle aluminium and seals.

Dominar Service Costs in Pune

Service	Cost
General service (oil, filter, chain, brakes, coolant check)	From ₹1,199
Oil change only (~1.7 L + labour)	From ₹999
Major service	From ₹1,599
Air filter replacement	₹300 – ₹700
Spark plug replacement	₹250 – ₹600
Chain + sprocket kit	₹3,000 – ₹5,500
Brake pad replacement (front disc)	₹500 – ₹1,200
Coolant replacement	Quoted on inspection

Annual running cost: roughly ₹6,000 – ₹10,000 for typical usage of 8,000–12,000 km, covering two general services, an additional oil change, chain maintenance and consumables. Years requiring a chain kit or brake pads run higher.

Pricing confirmed before work begins, no advance payment. See our full pricing page.

Common Dominar Issues in Pune

Fan running constantly in traffic. Normal to a degree on a liquid-cooled bike this size. Constant operation with a higher-than-usual temperature reading means coolant or radiator attention.

Chain wear. The Dominar puts substantial torque through its chain, and Pune’s dust and monsoon water strip lubricant quickly. Clean and lubricate every 500 km — it makes a large difference to chain kit life, which is an expensive item on this bike.

Brake pad wear. A heavy bike with strong brakes goes through front pads faster than owners expect in city use. Check thickness at every service.

Heat in traffic. The Dominar radiates noticeable heat to the rider in stationary traffic. That is characteristic rather than faulty, but a well-maintained cooling system keeps it manageable.
