KTM 390 Adventure Maintenance Schedule

2020 Ktm adventure 390 white and orange feature image

This is the maintenance schedule and service intervals for the KTM 390 Adventure, KTM’s smallest bike in their adventure line.

It uses the same engine block as in the KTM RC390 and KTM 390 Duke, so the maintenance schedule has a lot in common. The 390 Adventure is powered by a single-cylinder fuel-injected engine that makes peak power of 32 kW (43 hp), with 37 Nm (27 ft-lb) of peak torque.

It was built to compete in the compact adventure sports market, alongside other bikes like the Versys-X 300.

What you need to service your KTM Adventure Duke

Servicing your 390 Adventure is fairly easy, as it’s a single-cylinder engine with exposed parts. So when the valve service comes up every 15000 km it’s not an overwhelming task.

Aside from basic motorcycle maintenance tools, here’s what you need to service your 390 Adventure.

PartKTM 390 Adventure spec
Engine oilThe manual requires SAE 15W-50 oil that meets JASO T903 MA2 spec, and recommends Motorex oils, e.g. Motorex Top Speed 15W-50, a full synthetic.
Oil filterUse a Hiflofiltro HF155 as a high-quality drop-in replacement.
Spark plugStandard spark plug is a Bosch VR6NEU, which is quite hard to find other than from KTM dealers.
Fork oilUse SAE 4 fork oil, e.g. Motorex 4W Fork Oil which KTM recommends.
Air filterUse a K&N KT-1217 air filter.
Brake fluidUse a DOT 4 fluid e.g. Castrol DOT 4 full synthetic.
CoolantThe manual calls for Motorex Coolant M3.0, which is an OAT coolant based on ethylene glycol that’s silicate, nitrite, amine, borate, and phosphate free. (Most coolants contain at least phosphates or silicates… be wary)
Clutch cable lubeUse either engine oil or Protect all cable life, an affordable and quality lubricant.
Chain maintenanceUse Motul chain paste, a low-mess, high-quality chain lube. The manual recommends the more expensive Motorex chain lube.
GreaseThe manual recommends Motorex Bike Grease 2000 although you can use any lithium soap-based grease.

Maintenance schedule for the KTM 390 Adventure

The schedule below comes straight from the manual, though it has been formatted slightly to look better on a web page.

The maintenance schedule for the KTM 390 Adventure comes in two parts: required work and recommended work.

KTM recommends most of the work be done by mechanics, and users only do the following:

  • Check brakes (maybe replace if necessary)
  • Check/adjust tyre pressures
  • Check/adjust chain tension
  • Check coolant and brake fluid levels

And very little else. Of course, servicing the 390 Adventure isn’t hard as a single-cylinder mostly-naked bike, so it’s up to you.

Required work

The required service has a break-in, 7,500km, and 15,000 km service. The last two services are repeated every 7,500 and 15,000 km respectively.

Some items are every 1-2 years. Attend to each item whenever the sooner of the distance or time interval has arrived.
