Royal Enfield Scram 411 Maintenance Schedule and Service Intervals

This is the maintenance schedule and service intervals for the Royal Enfield Scram 411, a compact scrambler/everyday adventure bike from Indian motorcycle company Royal Enfield.

The Royal Enfield Scram 411 is an everyday scrambler-style motorcycle built around the Himalayan’s LS410 air/oil-cooled 411-cc single overhead cam two-valve single-cylinder engine. It’s an extremely simple engine with a claimed 24.5 hp peak power at 6000 rpm — not winning any races, but it doesn’t claim to, either.

While it shares an engine, the Scram 411 has a different aesthetic from the Himalayan, and has different wheels, tires, and suspension travel.

See other Royal Enfield Himalayan / Scram maintenance schedules:

The Scram 411 came with the fuel-injected BSVI engine from the get-go.

Royal Enfield Scram 411 Service Intervals

The Royal Enfield Scram 411 has 5000 km / 3000 mile or six-monthly service intervals, at which you have to check / adjust the valve clearances, check the spark plug, and check most of the motorcycle for leaks and lubrication.

While the valve clearance check is very short compared to most motorcycles, the single cylinder, two-valve engine’s clearances are very easy to check and to adjust, being a screw-and-locknut type adjustment.

The oil change service interval is wider — you only change the oil and filter every 10000 km / 6000 miles or 12 months, which is in line with most air-cooled motors.

What you need to service the Royal Enfield Scram 411 TO DO

PartRoyal Enfield Scram 411 Spec
Engine oilOil changes every 10K km / 6K miles. Manual calls for SAE 15W-50 API SL Grade JASO MA 2 Semi-Synthetic, e.g. Mobil 1 15W-50.
Oil filterYou need a Scram 411 Oil Filter Kit which includes washers and gaskets to replace the oil filter (which is every time you change the oil).
Spark plugBosch UR5CC (0.7-0.8mm gap) 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. K&N part number is RB-0510 for a universal clamp-on.
Brake fluidThe manual calls for DOT 4 brake fluid, e.g. Castrol DOT 4
Fork oilUse 10W weight fork oil, with viscosity range 35 e.g. Honda SS-8
Head lampThe front headlamp is a H4 60/55W bulb
Brake lampThe rear brake lamp is a 4/1W 12V LED
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 Scram 411

Royal Enfield Scram 411 maintenance schedule

Below is the maintenance schedule for the Royal Enfield Scram 411.

We’ve simplified it a lot for legibility while keeping all the detail of the full schedule from the owner’s manual.

We separated out the maintenance schedule into two sections for clarity:

  1. The core service schedule of important items like oil changes, spark plug inspections, and valve clearance checks
  2. The standard service checklist, to be done at every service.

Notes on the maintenance schedule

  • The Scram 411, like the Himalayan, includes free service up to 15000 km or 18 months — whichever arrives earlier. (i.e. the first three services)
  • Keep following this maintenance schedule in the pattern shown.

Royal Enfield Scram 411 — Standard service checklist

Tappet settings for the Scram 411

Since you need to regularly check / set the valve clearances on the LS410 engine, it’s good to know have the target clearances on hand. The tappet settings for the Royal Enfield Scram 411 are

  • Inlet: 0.08 – 0.10mm (~1/10 turn)
  • Exhaust: 0.23 – 0.25mm (~1/4 turn)

Remember to only check valve clearances when the engine is cold and the piston is at top dead centre.

Generally speaking, to check the valves on the Scram 411, you take the plug out, put something soft (like a zip tie) in the plug hole to find TDC for the intake valve (where the exhaust valve doesn’t move when you rotate the engine back and forth), loosen the lock nuts, turn the adjuster, then back off until you reach target spec — about 1/10 of a turn (a bit less than 1/8) for the inlet valves, and 1/4 of a turn for the outlet valves. Or use feeler gauges if you’re not sure.

Royal Enfield recommends a special tool to adjust the tappets, with part number “ST-27527-2”. This tool lets you hold the locknut in place while you adjust the tappet, and then tighten the locknut without disturbing the tappet adjuster.

Tyre sizes and pressures for the Royal Enfield Scram 411

The Scram 411 ships with tubed tyres. Below are the tire size specs and the recommended pressures.

WheelTyre sizePressure (without-with pillion)
Front100/90-191.75-1.89 Bar (25-27 psi)
Rear120/90-172.25-2.39 Bar (32-34 psi)

Chain maintenance on the Royal Enfield Scram 411

Royal Enfield recommends you check the chain condition (including slack) every 600 miles / 1000 km.

To check the chain tension, move the chain up and down in its loosest part. The chain slack / free play on the Royal Enfield Scram 411 should be 20-30mm.

To tighten the chain:

  1. Loosen the rear wheel nut.
  2. Loosen lock nuts of the chain adjuster on both ends of the swing arm.
  3. Tighten (or loosen) the adjuster nuts as necessary. Keep checking the chain slack. Make sure you adjust them by the same amount, using the markings as guides.
  4. Tighten the lock nuts.
  5. Tighten the rear wheel nut.

About the Royal Enfield Scram 411

Royal Enfield Scram 411

The Royal Enfield Scram 411 is Royal Enfield’s entrant into the popular “Scrambler” category of bikes. It’s a simple, pared-back motorcycle with some off-road ability but a lot of street cred at the same time.

The Scram 411 is based on the same platform as the Royal Enfield Himalayan. It is based around a 411-cc air/oil-cooled engine that is tuned for usable torque and not much top-end power — one of the frequent comments about both bikes (“it could do with a bit more top-end…”). The chassis and most of the ride gear are the same too, including the brakes (another source of wistful comments).

But the Royal Enfield Scram 411 has a smaller 19-inch front wheel and an adjusted ride position. It’s much more oriented towards everyday riding and occasional off-roading. It doesn’t excel at either, but it’s also a charming bike that people really enjoy riding and working on.

On the road, the engine is comfortable at about 100 km/h or 60 mph, but acceleration beyond this point is anything but swift. You can accelerate, but it’ll take a while, and reward you with a lot of wind blast and footpeg vibration. This means that high-speed interstates is not a very happy place for the Scram, so seek roads less travelled.

Offroad, the Scram 411 is able to do dirt roads and rocky tracks, but of course it won’t have the agility of a similarly-priced entry-level dual sport. It just doesn’t have very good suspension, and while the ground clearance and suspension travel is decent, this is no dirt bike.

The suspension is not adjustable, and so is sometimes uncomfortable on big bumps.

Where the Scram excels is in the simplicity of the package. First-time mechanics would really appreciate that it’s technically possible to grasp nearly everything going on in a Royal Enfield Scram 411. A lot of home maintenance tasks are quite easy, relatively speaking — even the valve service (if you have the right space and tools). You will still need a paddock stand and a front stand to remove the wheels to change the tubes, however.

That said, the Scram 411 does have some high-tech bits, like the simple but effective turn-by-turn navigation system, the Tripper. The combination of the analogue and digital dash plus the second dial for the Tripper is pretty handsome.

Maintaining the Royal Enfield Scram 411 involves frequent valve checks, both at break-in and every 3000 miles, as well as oil changes every twice that interval (6000 miles or annually).
