Yamaha R15 & MT-15 Service Schedule, KM List & Cost 2026

The Yamaha R15 and MT-15 share the same 155cc liquid-cooled VVA engine beneath very different bodywork, which means they share the same service schedule, the same oil specification and the same maintenance priorities. If you own either, this guide applies to both.

These are not commuter bikes, and servicing them on commuter-bike assumptions is the most common mistake owners make.

Quick answer: four free services at 1,000 / 4,000 / 7,000 / 10,000 km, then every 3,000 km. Engine oil ~1.0 litre, 10W-40 synthetic, JASO MA2.

R15 & MT-15 Service Schedule — KM List

Service	KM Milestone	Time	Type
1st Service	1,000 km	30 days	Free — running-in service
2nd Service	4,000 km	150 days	Free
3rd Service	7,000 km	270 days	Free
4th Service	10,000 km	390 days	Free
Subsequent	Every 3,000 km	Every 120 days	Paid — from ₹1,199

Each milestone is km or days, whichever comes first. A low-mileage R15 still reaches its next service on the calendar, and letting the window pass forfeits a free service — something owners who only ride at weekends lose regularly.

Older, pre-BS6 Yamahas follow a different schedule. Legacy models were sold with three free services at 1,000 / 5,000 / 10,000 km, then periodic maintenance every 5,000 km or 180 days. If your R15 predates BS6, check the service booklet that came with it rather than assuming the current chart applies.

The 3,000 km periodic interval after the free services surprises people, but it is Yamaha’s own figure — and on a high-revving 155cc engine in Pune traffic it is entirely reasonable.

What Happens at Each Service

1st Service — 1,000 km

The running-in service, and genuinely the most consequential one the bike will ever have. The piston rings and bearings have just bedded in, and the first fill of oil is carrying the fine metal particles that process produces. Leaving it in place circulates that debris through a high-revving engine.

Includes engine oil change, bolt tightening as the chassis settles, chain slack adjustment, brake check, clutch adjustment, coolant level check and full inspection.

Use the free Yamaha service for this. It is covered under warranty and there is no advantage to doing it elsewhere.

2nd Service — 4,000 km (150 days)

Full general service: engine oil change with 10W-40, air filter cleaning, spark plug inspection, chain cleaning and lubrication with correct slack, brake pad inspection front and rear, coolant level and condition check, and a full electrical check.

3rd Service — 7,000 km (270 days)

Everything above, plus air filter replacement if cleaning is no longer effective, chain and sprocket wear measurement, brake pad thickness assessment, and a charging system voltage test.

4th Service — 10,000 km (390 days)

Drivetrain focus. The chain and sprocket set typically reaches the end of its useful adjustment range around here on a bike ridden enthusiastically. Coolant condition gets proper assessment, and brake pads are commonly replaced.

5th Service Onward — Every 3,000 km (paid)

Major service. Comprehensive inspection across engine, cooling, drivetrain, brakes, electrical and suspension, with air filter replacement, likely chain and sprocket replacement, brake service, spark plug replacement and battery health test.

Engine Oil — Capacity, Grade and Interval

Specification	R15 V4	MT-15
Oil capacity	~1.05 L	~1.0 L
Grade	10W-40	10W-40
Minimum type	Semi-synthetic	Semi-synthetic
Recommended	Fully synthetic	Fully synthetic
Rating	JASO MA2	JASO MA2

Oil change interval: Yamaha specifies 4,000–6,000 km. Our Pune recommendation:

Riding pattern	Recommended
Hard riding / frequent high revs	Every 3,000 km
Daily city commuting	Every 3,500 – 4,000 km
Mixed use	Every 3,000 – 4,000 km
Low usage	At least once every 12 months

Two reasons to stay at the shorter end:

High specific output stresses oil. The 155cc VVA engine revs well past 10,000 rpm and produces far more power per cc than a commuter engine. That puts significantly more thermal and shear stress on the oil. Oil that would comfortably last 5,000 km in a Splendor does not last 5,000 km here.

City traffic is the worst case for a liquid-cooled sport engine. These engines shed heat through a radiator that needs air moving across it. Stationary in traffic there is no airflow, so the fan works and the engine soaks. An R15 commuting daily through Baner or Kharadi works its oil harder than the same bike doing weekend highway runs.

JASO MA2 matters. Both bikes use a wet clutch running in engine oil. Friction modifiers in car oils cause clutch slip — the revs climb without matching acceleration, most obvious in higher gears.

Coolant — The Item Sport-Bike Owners Forget

If you moved to an R15 or MT-15 from an air-cooled commuter, coolant is maintenance you have never had to think about.

Coolant contains corrosion inhibitors that deplete over time. Once they are gone the fluid still circulates and still looks fine, while the aluminium internals corrode and radiator efficiency drops. The first symptom is usually the fan running more than it used to and the temperature reading sitting higher.

• Check the level monthly, cold, on level ground.
• Never top up with plain water except as a genuine roadside emergency — water corrodes and boils too readily.
• Never use car coolant. Many automotive coolants are silicate-based and can attack motorcycle aluminium and seals.
• Have condition assessed at every service, not just level.

In a Pune May, a liquid-cooled sport engine sitting in Hinjewadi traffic at 42°C ambient is asking a lot of its cooling system. Degraded coolant is exactly when that system lets go.

VVA — What It Is and What It Needs

Yamaha’s Variable Valve Actuation switches between two cam profiles: a low-lift profile below roughly 7,400 rpm for efficiency and smooth low-end response, and a high-lift profile above it for peak power. It is the reason these bikes feel docile in traffic and urgent when extended.

The system needs no separate servicing. What it does need is clean engine oil at the correct level, because the actuator is oil-operated. Degraded, contaminated or low oil is far and away the most common cause of complaints about VVA behaviour — inconsistent switching, or the top-end pull feeling flat.

If your VVA feels off, change the oil before anything else gets investigated.

Common R15 & MT-15 Issues in Pune

Chain wear. These bikes put considerably more torque through the chain than a commuter, and Pune’s dust plus monsoon water strips lubricant fast. Clean and lubricate every 500 km — this single habit roughly doubles chain kit life.

Fan running constantly in traffic. Some fan operation when stationary is entirely normal. Constant running with a higher-than-usual temperature reading points to coolant or radiator attention.

Brake pad wear. Front disc pads on a sport bike wear faster than most owners expect, particularly with city riding. Have thickness checked at every service.

Rough idle or flat top-end. Usually degraded oil affecting VVA operation, or a clogged air filter, before anything more serious.
