Royal Enfield Interceptor 650 (INT 650) Maintenance Schedule and Service Intervals

Royal Enfield Interceptor 650 INT 650 red and white "Bakers"

This is the maintenance schedule for the Royal Enfield Interceptor 650, one of the “650 twins” produced alongside the Continental GT 650. The Royal Enfield Interceptor 650 is also referred to as the INT 650.

The Interceptor 650 is an upright standard bike that’s reminiscent of modern classic British-style motorcycles like the Triumph Bonneville 865 (EFI) or Kawasaki W800.

It’s powered by an air/oil-cooled parallel-twin 648cc SOHC engine with a mild 9.5:1 compression ratio. It makes a very modest 35 kW @ 7150 rpm, and 52 Nm @ 5150 rpm. Power goes to the ground via a 6-speed transmission and a chain drive.

The bike is learner legal in countries/regions like Australia, New Zealand, and Europe, where learners are limited to certain power limits or power:weight ratios.

What you need to service the Royal Enfield Interceptor 650

PartRoyal Enfield Interceptor Spec
Engine oilOil changes every 10K km. Manual calls for SAE 10W-50 API SL (or higher) or JASO MA2-rated fully synthetic oil, e.g. Castrol Power 1 10W-50.
Oil filterRoyal Enfield wants you to order the filter from their website, but you can use a Mobil 1 M1-104A.
Spark plugBosch UR5CC (0.7-0.8mm) per the manual. This is equivalent to the NGK CR8E.
Air filterYou need to clean the air filter periodically but replace it when you change the oil — or more often if you ride it in the dirt. Use DNA air filter R-RE65N18-01.
Brake fluidThe manual calls for DOT 4 brake fluid, e.g. Castrol DOT 4.
Fork oilThe manual specs 2W 25 HPCL fork oil.
Head lampThe front headlamp is a H4 60/55W bulb
Brake lampThe rear brake lamp is a P21/5W Halogen.
ChainUse a chain lubricant like Motul chain paste periodically to keep the chain fresh.
GreaseUse lithium soap-based grease for general greasing (bearings, swing-arm, kickstand etc.)

Maintenance schedule for the Royal Enfield Interceptor 650

Below is the maintenance schedule for the Royal Enfield Interceptor 650, taken from the manual and reformatted slightly.

The recommended schedule is based on ordinary riding conditions. The manual takes pains to state that if you ride it more severely (e.g. in a dusty environment) you’ll have to service your Interceptor 650 more often.

For maintenance after 30,000 miles/ 50,000 kms, continue with the same frequency as observed in the schedule (adjusting for how intensely you use your bike).

Noteworthy items in the maintenance schedule are

  • You have to adjust the valve clearance every 5,000 km!
  • There’s no coolant to change — this baby’s air-cooled

Legend and notes on the maintenance schedule:

  • I : Inspect (Clean, Adjust, Lubricate or Replace if necessary)
  • L : Lubricate
  • R : Replace
  • C: Clean
  • #: After the first service, engine oil and engine oil filter replacement is mandatory every 12 months even the vehicle has not covered the specified distance.
  • **: After the first service, valve clearance adjustment is mandatory every 12 months even if the vehicle hasn’t covered the specified distance.

About the Royal Enfield Interceptor 650

The Royal Enfield Interceptor 650 was a huge departure for Royal Enfield from what it used to do historically. Known for its shaky singles, Royal Enfield was suddenly producing a twin. And what a looker of a twin!

As soon as you see it you think “ah, this looks familiar”. The Interceptor 650 looks a lot like a classic vintage British motorcycle like something from Triumph or Norton (or Kawasaki, who also have a lot of British history).

The Royal Enfield Interceptor 650 ticks a lot of boxes for what people wanted to come out of Royal Enfield. Royal Enfield was a cool brand before the 650 twins, known for having a retro/classic vibe (and reality… their bikes are pretty old tech), and some really nice looking bikes.

But the 650 twins delivered a lot of new stuff that people wanted. These included

  • A bigger, more torquey/powerful engine. Still not huge, but now at least it can keep up.
  • ABS brakes (new riders like having it)
  • Fuel injection
  • Even better looks!
  • More cylinders! And even better, it’s a parallel twin in 270-degree configuration.

Royal Enfield did all this with the INT 650 and still kept the entry price of it very low. It’s definitely one of the best-looking bikes for the money you can buy. But you feel the savings in the suspension, which are a quick upgrade for anyone thinking of riding it as a performance machine.

One compelling part of the Interceptor 650 is the engine that has so much room for modification. Stock it runs a 9.5:1 compression ratio — very low, and suitable for all kinds of bad gas. The camshaft timing is also quite gentle. So you can liven up the engine quite a bit with a camshaft upgrade (which is cheap, as it’s SOHC), a simple exhaust upgrade, and a dyno tune. So around $1000 of work makes the bike a lot livelier.

People concerned about power output in everyday riding needn’t be. The bike peaks in torque just as it’s reaching 75 mph (or 130 km/h), and it still has pull up to around 90 mph (150 km/h). Beyond that, it doesn’t feel too comfortable. But most people wouldn’t buy a bike like this to sustain high speeds like that. Yes, some freeway droning almost requires it in Europe and the US, but if you do that often, you might be looking at the wrong bike.

Another impressive thing about the RE INT 650 is the handling. Again, it isn’t just “good for the price” — it’s good. The bike isn’t heavy (202 kg wet — a Triumph Bonneville 865 is 225kg wet) and so the stock suspension and brakes are easily up to the task. It doesn’t feel out of shape at high speeds (high for this bike) or in windy roads.

The Royal Enfield Interceptor 650 isn’t just a good bike for the price — it’s a good bike.

The only fly in its ointment are the 5,000 km valve inspection intervals. But luckily, service guides are widely available Get your wrenches out.

Manual for the Royal Enfield Interceptor 650

One of my favourite things about Royal Enfield is that they love it when people do their own maintenance, and their owners’ manuals are basically service manuals. You can find guides to doing the valve service online in many places.

The maintenance schedule above was from the manual for the Interceptor INT 650 model. You can get the manual from here. We also compared it to the US manuals (there’s an air injection system added for emissions reasons, but that’s it.)
