KTM 690 Enduro R (2019+) Simplified Maintenance Schedule

This is the simplified maintenance schedule for the KTM 690 Enduro R as made from 2019 onward.

In 2019, KTM updated its long-running KTM 690 Enduro R significantly revised the engine, giving it more power and fewer vibes by way of a counterbalancer.

As previously, the 2019 KTM 690 Enduro R is based on a 690cc SOHC 4-valve engine with ride-by-wire and two spark plugs. The 2019+ KTM 690 Enduro R makes peak power of 55 kW (74 hp) at 8000 rpm — making the ~160 kg / ~350 lb (fully-fueled) dual sport bike quite spritely.

But the 2019+ KTM 690 Enduro R is much smoother than its predecessor, and also has a lot more keep-you-alive electronics.

The KTM 690 Enduro R is still being made, not really threatened by the parallel twin-powered KTM 890 Adventure R.

KTM 690 Enduro R Service Intervals

The KTM 690 Enduro R has a single-cylinder engine that’s tuned quite aggressively, so the service intervals are appropriately short.

You have to do a service on the 690 Enduro R every 10000 km (6200 miles), at which point you change the oil and filter, clean the oil screens, change the air filter and fuel screen, and check the valve clearances.

Luckily the valve clearance check isn’t too involved, as there’s just one piston and the valves are easy to read and adjust.

Spark plug changes are every two services, but while you have the plugs out for the valve service you should inspect them.

Finally, keep you brake fluid and coolant up to date, every two and four years respectively.

What you need to service your KTM 690 Enduro R (2019+)

Aside from basic motorcycle maintenance tools, here’s what you need to do a service on your KTM 690 Enduro R.

PartKTM 690 Enduro R spec
Engine oilThe manual specifies Motorex Power Synthetic 4T 10W/50, or another SAE 10W-50 fully synthetic engine oil that meets JASO T903 MA2 spec, e.g. Motul 7100 10W-50.
Oil filterUse part number 58038005100 or Hiflofiltro part HF155, a popular equivalent. (This oil filter is used in most KTM adventure bikes.)
Fork oilThe manual recommends SAE 4 fork oil, e.g. Motorex 4W fork oil.
Brake fluidThe manual requires DOT 4 or DOT 5.1, recommending Castrol DOT 4 or Motorex DOT 5.1 brake fluid.
Air filterUse a K&N KT-6908 air filter, which has been the same on all 690 Enduro R models since 2009.
CoolantKTM recommends Motorex Coolant M3.0 or other “high-grade, silicate-free coolant with corrosion inhibitors”.
Spark plugYou need two NGK Iridium IX spark plugs — LKAR9BI-10 for the inside spark plug, and LMAR7DI-10 for the outside spark plug.
Chain maintenanceUse Motul chain paste, a conveniently small and highly regarded chain lubricant.

Check that the electrical system is functioning properly.
Check the front brake linings.
Check the rear brake linings.
Check the brake discs.
Check the brake lines for damage and tightness
Check the front brake fluid level.
Check the rear brake fluid level.
Check the hydraulic clutch fluid
Check the free travel of the foot brake lever
Check the shock absorber and fork for leaks. Perform service as needed and depending on how the vehicle is used.
Check the steering head bearing play
Check the wheel bearing for play
Check the tire condition
Check tire pressure
Check the spoke tension
Check for rim run-out
Check the chain tension
Check the antifreeze and coolant level
Check the cables for damage and routing without kinks
Check the fuel pressure.
Check that the radiator fan is functioning properly.
Check all hoses (fuel, coolant, bleeder, drainage, etc.) and sleeves for cracking, tightness, and incorrect routing
Empty the drainage hoses
Check the tightness of the safety-relevant screws and nuts which are easily accessible.
Grease all moving parts (e.g. side stand, hand lever, chain, etc.) and check for smooth operation with lithium soap-based grease
Final check: Check the vehicle is roadworthy and take a test ride.
[Dealer] Read out the error memory after the test ride using the KTM diagnostics tool.
[Dealer] Set the service interval.

Chain Maintenance

KTM recommends you maintain the chain according to the following schedule for your 690 Enduro R.

Chain maintenanceEvery
Clean and lubricate the chain (use Motorex Chain Clean)1000 km / 620 mi, or after riding in rain or washing the motorcycle
Check chain tension, and adjust as necessary
Chain tension: 5mm / 0.2 in between chain, when taught, and swing arm
10000 km / 6200 mi
Chain maintenance – KTM 690 Enduro R

To measure the chain tension, do the following.

  1. Put the transmission in neutral and raise the motorcycle onto a track stand or the side stand.
  2. Move the chain so that any tight position is in the middle of the chain, between the sprockets.
  3. Push the chain upward with a finger.
  4. Measure the distance between the sliding guard and the chain. This should be 5mm on the 690 Enduro R.
  5. To adjust chain tension, loosen the axle nuts, adjust the chain tension with the adjusting screws, and re-tighten the axle nuts to 90 Nm / 66 ft-lb.

About the KTM 690 Enduro R

The KTM 690 Enduro R is KTM’s big “enduro” bike — basically a distance-capable dirt bike.

While KTM has been making the 690 Enduro R since 2012, the bike has evolved in a couple of important ways. Over time, KTM has made the engine more powerful AND more smooth, thanks to an extra spark plug, a counter balancer shaft, and a more aggressive tune.

The KTM 690 Enduro R is powered by a 693 cc single with a 105/80mm bore and stroke, a single overhead cam, and four valves. It runs an aggressive tune and makes peak power of 55 kW (74 hp) at 8000 rpm, with torque all through the rev range.

The engine in the 690 Enduro R is a significant upgrade over the previous gen 2014-2018 dual spark KTM 690 Enduro R. It has a shorter stroke, more aggressive power tune, and counterbalancers to keep it smooth for highway time.

So thew 2019+ KTM is a huge favourite for enduro riders who take the 690 Enduro R on all kinds of gnarly trails, and even endure some highway stints in between. It’s capable of doing highways, though you don’t want to do them at high speed for long stints.

The 2019+ KTM 690 Enduro R gets a host of rider aids too, like lean angle-sensitive ABS and traction control, via its IMU.

Ride gear on the 690 Enduro R is simple but competent — a single 300mm disc with a Brembo 2-piston caliper up front, and a 240mm disc with a 1-piston caliper at the rear.

As the Enduro R is an “R” model, it also has high-end suspension. The front fork is a compression and rebound adjustable 48mm WP XPLOR fork, and the rear shock is a WP XPLOR shock with a Pro-Lever linkage.

The shock is adjustable for preload, rebound damping, and even high and low-speed compression damping.

The KTM 690 Enduro R doesn’t really have any direct parallels other than in motorcycles built on the same platform, like the Husqvarna 701 Enduro.

KTM sells the 690 Enduro R alongside other middleweight adventure bikes like the KTM 890 Adventure, which haven’t taken its place. There’s just something special about the 690 — it’s light and it’s very capable..

Tires and pressures for the KTM 690 Enduro R (2019+)

The KTM 690 Enduro R ships with Mitas E-07 tyres, but you can of course give it anything from street to full on off-road tyres.

It has a very offroad-friendly 21/18 tyre size combination.
