First service at 1,000 km
The first service matters more than any visit after it: it drains the oil that carried the metal particles of engine break-in. Booked at a dealer it runs about €140, and skipping or stretching it is the cheapest way to buy an expensive problem. Here is what the workshop does:
- Engine oil and filter change
- Chain tension, wear and lubrication
- Brake pads, discs and fluid level check
- Spoke tension and fastener torque check
- Electronic diagnostic read-out
By calendar, not odometer
| Engine oil and filter | every 12 months if the distance interval is not reached |
|---|---|
| Brake fluid | every 2 years |
| Coolant | every 3 years |
| Fork oil | every 20,000 km or 2 years with regular offroad use |
| Battery | load test yearly; typical life 4 to 5 years |
What each service costs
Dealer estimates from the labour and parts assumptions below. DIY removes the labour line entirely.
| First service1,000 kmBreak-in oil and filter change plus the full checklist; flushes out running-in metal | ~€140 |
|---|---|
| Routine serviceevery 10,000 km or 12 monthsOil and filter, ~1.7 L, chain and brake checks, 1 h labour | ~€140 |
| Valve check serviceevery 20,000 kmRoutine service plus 2 h of valve work and new spark plugs | ~€355 |

What to buy for the 390 Enduro R's next service
Editorial picks are checked for fitment. Spec searches carry the manual's grade or size straight into Amazon; match the listing to it yourself.
- See price at Amazon
Engine oil
Motorex Cross Power 4T 10W/50, 4 L
The spec sheet asks for full synthetic 10W-50 meeting JASO MA2, and this is the oil KTM fills at the factory. Paying for the brand on the sticker is optional; meeting the spec is not.
A 4 L jug covers two full changes with top-up to spare

Oil filter
Oil filter for the KTM 390 Enduro R
Filters are keyed to the engine, not the badge. Check the listing's fitment names the 390 Enduro R and its model year before buying; the part number in the manual settles any doubt.
- Find at Amazon
Drive chain
520 pitch drive chain
Pitch is fixed at 520; link count is not. Count the links on the chain coming off, or read the manual, before ordering. An X-ring chain costs more and outlasts a plain one.
- Find at Amazon
Front tyre
90/90-21 front tyre
Size is exact and not up for debate. Speed and load ratings must meet or exceed the manual's; compound and tread pattern are where taste comes in.
- Find at Amazon
Rear tyre
140/80-18 rear tyre
Same rule as the front: size exactly as listed, ratings at or above the manual's. Buying front and rear as a matched pair keeps the handling the factory set up.

What 390 Enduro R owners actually watch
- Same LC4c single as the 390 Adventure R: religious 1,000 km first service, then famously undemanding.
- Real dirt use makes the air filter a per-ride check and spoke tension a weekly one.
- The stock road-biased tyres are the first thing serious owners replace; knobblies transform it and change chain clearance checks.
Frequently asked

- Every 20,000 km. Budget around 2 hours of workshop labour plus spark plugs when it comes due.
- Is the KTM 390 Enduro R cheap to maintain?
