Royal Enfield Continental GT 650 Maintenance Schedule and Service Intervals

This is the maintenance schedule for the Royal Enfield Continental GT 650, one of the “650 twins” produced alongside the Interceptor 650.

The Continental GT 650 is a “cafe racer” style retro bike that’s reminiscent of modern classic British-style motorcycles like the Triumph Thruxton 900 or the Kawasaki W800 Café. It is very similar to the Interceptor 650 but has clip-on handlebars. The handlebars aren’t too low, and it’s still overall quite a comfortable ride.

The GT 650 is powered by an air/oil-cooled parallel-twin 648cc single overhead camshaft 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 Continental GT 650 is learner legal in countries/regions like Australia, New Zealand, and Europe, where learners are limited to certain power limits or power:weight ratios. Definitely one of the coolest learner bikes you can buy.

What you need to service the Royal Enfield Continental GT 650

Servicing your Continental GT650 is quite easy. It’s an air-cooled twin with a chain drive. Also, luckily, most of it is exposed and it’s easy to lift the tank to get at the important bits (like to do a valve service).

PartRoyal Enfield Continental GT 650 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 parts for the Royal Enfield Continental GT 650

Maintenance schedule for the Royal Enfield Continental GT 650

Below is the maintenance schedule for the Royal Enfield Continental GT 650, taken from the manual and reformatted slightly. (The Interceptor 650 has its own, separate manual.)

There are two separate parts:

  1. Regular service every 600 miles / 1000 km (or every major ride), and
  2. The longer-term maintenance schedule

Regular service

Do the following checks on your Royal Enfield Continental GT 650 every 600 mi / 1000 km.

ComponentRegular service
Engine oilCheck oil level and top up if necessary (Castrol Power 1 10W-50)
Clutch cableCheck cable free play. Adjust if necessary
Hand leversCheck hand levers pivot point for smoothness. Lubricate if necessary
Drive chainClean, lubricate, and adjust chain
Regular service — Continental GT 650

Maintenance schedule

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 Continental GT 650 more often.

For maintenance after 30,000 miles/ 50,000 km, 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
  • The below maintenance schedule is abridged at 12000 miles / 20000 km for ease of legibility. Repeat every item every 1, 2, 3, or 4 intervals.

Tyres and tyre pressures for the Continental GT 650

The Continental GT 650 ships with tubeless tyres but fitted with inner tubes (that’s what it says in the manual, I swear). The same tubes/tyres are used on both the GT 650 and the Interceptor 650. Below are the tire size specs and the recommended pressures.

WheelTyre sizeTyre pressure
Front100/90-18 M/C 56H2.2 Bar Bar (32 psi)
Rear130/70-18 M/C 63H2.5-2.75 Bar (36-29 psi)
(depending on riding with/without pillion)

The brand of tyre the bike ships with are Pirelli Phantom Sports Comp tyres, which are very competent. But you can fit any other class of street tyres on there.

About the Royal Enfield Continental GT 650

Gloss steel royal enfield continental gt 650

When Royal Enfield announced the Royal Enfield 650 twins, they represented a significant change for Royal Enfield from what it used to do historically.

Royal Enfield was always known for its shaky singles like in the iconic Bullet. So it was quite surprising when Royal Enfield started producing a twin — and in two styles.

The Continental GT 650 borrows some style elements from the Continental GT 535… but that’s about it. Yes, that bike looked good, and was a good basis for a lot of improvement work, but many owners wanted a stronger chassis and more power. The 535 has been discontinued, replaced entirely by the twin.

The Royal Enfield Continental GT 650 is quite a unique bike for 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, like the aforementioned GT 535.

But the 650 twins (including the Continental GT 650) delivered a lot of new features that people wanted before making a shift to the Indian brand. These included

  • A bigger, more torquey/powerful engine. Still not huge, but now at least it can keep up with traffic on high-speed interstates.
  • ABS brakes (a regulatory requirement, but enjoyed by new riders)
  • Fuel injection
  • More cylinders! Well, one more. And even better, it’s a parallel twin in 270-degree configuration.

Royal Enfield did all this with the Continental GT 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. In any country in the world where it’s sold — India, the UK, the US, or Australia — a parallel twin bike with great style, ABS brakes, and easy serviceability is a compelling value proposition.

There are those who see a cafe racer and are worried about power output. It does seem to make less sense to be closer to a racer tuck when the top speed won’t go much past 140 km/h…

But the Continental GT 650 does have a lot of room for improvement. Stock, the parallel-twin engine 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 the base engine SOHC), a simple exhaust upgrade, and a dyno tune. So around $1000 of work makes the bike a lot livelier.

Of course, at that point you might also consider upgrading the brakes and suspension.

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 Royal Enfield Continental GT 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 only fly in the ointment of the Continental GT 650 is the 5000 km valve service interval. But luckily, service guides are widely available. Get your wrenches out.

Manual for the Royal Enfield Continental GT 650

The maintenance schedule above was from the manual for the Continental GT 650 model.

One of my favourite things about Royal Enfield is that they’re very supportive of users doing their own maintenance. There are lots of service resources online. You can find guides to doing the valve service online in many places.

You can get the manual from here. We also compared it to the US manuals, and aside from the air injection system (presumably for CA regulations), the schedule is the same.
