Owning a KTM Duke is more than just riding — it’s about maintaining power, precision, and performance. Whether you have a Duke 125, 200, 250, or 390, keeping your bike in top shape ensures smoother rides and a longer engine life.
To help you stay on top of your maintenance game, here’s the ultimate KTM Duke maintenance checklist every rider should follow 👇
1. Engine Oil & Oil Filter
Your Duke’s engine runs at high RPMs — meaning oil health is everything.
-
Check: Oil level every 1,000 km.
-
Replace: Engine oil every 5,000–6,000 km (use 10w50 or 20w50 grade).
-
Tip: Always change the oil filter along with the oil to keep lubrication clean and efficient.

2. Air Filter
A clogged air filter chokes your engine, affecting pickup and mileage.
-
Check: Every 2,000–3,000 km (clean if reusable).
-
Replace: Every 5,000–7,000 km, or sooner if you ride in dusty areas.
-
Upgrade Option: Try a BMC performance air filter for better airflow and throttle response.

3. Chain & Sprocket
A dry or loose chain reduces performance and increases wear — but how often you maintain it depends on where you ride.
-
Clean & Lube: Every 500–700 km on average.
-
Dusty / Off-road Conditions: Clean and lube more frequently, as dust and sand can cause faster wear and chain noise.
-
City / Highway Riding: Chain wear is lower, so applying chain lube regularly is usually enough between full clean-ups.
-
Check Tension: Maintain 2–3 cm of slack to avoid tight spots or jerky movement.

4. Brake Pads & Fluid
Your Duke’s power needs reliable stopping.
-
Inspect: Pads every 2,000 km for wear.
-
Replace: When thickness drops below 2 mm.
-
Brake Fluid: Change every 12 months — use DOT 4 for optimal braking performance.

5. Tyres & Pressure
Tyres affect grip, handling, and safety.
-
Check: Pressure weekly (front: 25–29 PSI, rear: 29–33 PSI).
-
Inspect: For cuts, cracks, or flat spots.
-
Replace: If tread depth is below 2 mm.
Pro Tip: Don’t forget to align and balance your wheels regularly for smoother rides.
6. Battery Health
A weak battery affects self-start, lights, and ECU performance.
-
Check: Terminals for corrosion and tightness.
-
Top-up (if applicable): Maintain electrolyte level.
-
Replace: Every 2–3 years or sooner if cranking becomes slow.
Buy genuine KTM-compatible batteries from MySpareMarket.
7. Electricals & Lights
Check that all indicators, headlights, tail lamps, and horn work properly. Faulty wiring or loose connectors can cause flickering — especially in older Dukes.
8. Coolant & Radiator
KTM engines run hot — keeping the cooling system healthy is crucial.
-
Check: Coolant level monthly.
-
Top-up / Replace: Every 12 months or 10,000 km.
-
Tip: Use only KTM-approved coolant for consistent performance.
9. Nuts, Bolts & Suspension
Vibrations can loosen parts over time.
-
Check: Handlebar, footpegs, brake lever, and exhaust mounts.
-
Inspect: Front forks and rear mono-shock for oil leaks or uneven movement.
10. Scheduled Service
No checklist replaces a professional KTM service. Follow your service intervals as per your owner’s manual, and use only genuine KTM parts to avoid performance loss.
