Triumph Scrambler 400 X / XC Maintenance Schedule
This is the maintenance schedule and service intervals for the Triumph Scrambler 400 X, released for 2024, and the Scrambler 400 XC, released from 2025 in some markets and 2026 in others. Triumph introduced the XC after the X, but both motorcycles use the same maintenance schedule.
Both models use Triumph’s 398 cc liquid-cooled, four-valve single-cylinder engine. It makes 29 kW (40 PS / 39.5 hp) at 8000 rpm and 37.5 Nm (27.7 lb-ft) at 6500 rpm. Both also have a slip/assist clutch, six-speed transmission, and chain final drive.
The Scrambler 400 XC is a more off-road-equipped version of the Scrambler 400 X. It adds side-laced spoked tubeless wheels, a high front mudguard, flyscreen, handguards, engine bars, an aluminium sump guard, and a headlight grille. It keeps the same engine, chassis, suspension, brakes, and final drive, so the service intervals and scheduled maintenance tasks are the same.
Both Scrambler models differ from the Triumph Speed 400 through their off-road protection, 19-inch front wheel, suspension, chassis, and gearing.
Here are the motorcycles in the Triumph 400 class:
- Triumph Scrambler 400 X
- Triumph Speed 400
- Triumph Thruxton 400
The Scrambler 400 XC looks more trail-ready, but the mechanical parts that determine its maintenance schedule are shared with the Scrambler 400 X.

Triumph Scrambler 400 X / XC Service Intervals
Both the Triumph Scrambler 400 X and 400 XC have 16,000 km (10,000 mile) or annual service intervals, whichever comes first. At every scheduled service, change the engine oil and filter and complete the listed checks.
Check the valve clearances on either model every 32,000 km (20,000 miles).
Both models have chain final drive, so clean, inspect, adjust, and lubricate the chain regularly. See the chain-maintenance section below.
Both also use the same liquid-cooling and brake systems, so their coolant and brake-fluid replacement intervals are identical.
Maintenance Schedule for Triumph Scrambler 400 X / XC
Below is the shared maintenance schedule for the Triumph Scrambler 400 X and 400 XC. Triumph presents it as one large table in the manual, so we’ve split it into three parts:
- The daily inspection checklist (leaks, general condition checks)
- The annual inspection checklist
- The maintenance schedule of less frequent things like spark plug changes and valve clearance checks.
In addition, the chain inspection guidelines are separate.
Daily inspection checklist
Below is the daily inspection checklist for the Triumph Scrambler 400 X and 400 XC. Do these checks along with the rest of the maintenance schedule.
You do many of these checks when starting out riding the motorcycle. However, it’s good practise to regularly check the engine oil level.

Maintenance schedule
The scheduled work below applies to both the Scrambler 400 X and 400 XC.
Notes:
- Follow the earlier of the time or distance interval. For example, do the annual inspection every 16,000 km (10,000 miles) or 12 months, whichever comes first.
- Keep repeating this maintenance schedule beyond the end of the indicated time/distance.
- At the end of the maintenance schedule, keep following it in the pattern shown.
- The break-in service is omitted for simplicity. It is an oil + filter change and a check for leaks, cracks, and damage.

Chain maintenance
Below are the shared chain-maintenance guidelines for the Triumph Scrambler 400 X and 400 XC.
Triumph recommends you lubricate your chain every 300 km (200 miles) or after riding through rain / wet (which will be often if you take it off-road!), and inspect the chain condition every service. You can use any good quality engine lube, but Motul chain lubricant is well-recommended.
Measure chain wear
To measure chain wear on a Triumph Scrambler 400 X or 400 XC:
- Hang a 10-20 kg weight off the bottom chain (e.g. a convenient kettlebell you have lying around…)
- In the top section of the chain, measure the length of 20 links (e.g. from 1st pin to 21st pin).
- Make the measurement a few times.
Target chain length over 20 links: 320 mm
If the chain is worn beyond that limit, then it’s time to replace it, rather than tighten it.
Replace the sprockets at the same time.
How to check chain slack on a Triumph Scrambler 400 X / XC
Every brand of motorcycle defines chain slack differently. For Triumph, slack is the free vertical movement of the centre part of the bottom chain segment.
- You need a ruler (or tape measure) and nitrile gloves or a rag (to avoid getting grease on your hands)
- Put the motorcycle in neutral, on a level surface, and elevate the rear wheel with a stand or center stand if you have one fitted.
- Rotate the wheel and find the tightest part of the chain, in the middle.
- Use a finger to lightly push the chain up and down. Measure the deflection, which is the chain slack.
Target chain slack (maximum deflection): 20–30 mm (0.8–1.2 in)
If the chain slack is not in that range, then you need to adjust it.
How to adjust chain slack on the Scrambler 400 X / XC
The procedure is similar to the one on many motorcycles, but of course, specifics (e.g. torque values) vary between brands and models.
You need wrenches and torque wrenches to re-tighten the rear wheel. You need a large torque wrench for the rear axle, as well as a breaker bar.
- Loosen the rear axle nut with a breaker bar.
- Loosen the lock nuts on the left- and right-hand sides.
- Turn the adjuster bolts, usually counter-clockwise, extending the bolt “outward” to lengthen the chain and make it tighter. (Sometimes you’ll want to make it looser — in those cases, turn it clockwise / inward)
- Make sure to adjust the bolts the same amount on each side — check the markings.
- Push the wheel into firm contact with the adjusters.
- Tighten both adjuster lock nuts to 11 Nm (8 lb-ft), and the rear axle nut to 98 Nm (72 lb-ft).
Wheel and Tire (Tyre) Specs for the Triumph Scrambler 400 X / XC
Both models use Metzeler Karoo Street tubeless tires in the same sizes and with the same recommended pressures. The Scrambler 400 X has cast-aluminium wheels, while the Scrambler 400 XC has side-laced spoked wheels with Excel aluminium rims. Check the XC’s spokes during routine wheel inspections.
| Wheel | Wheel size | Tire size | Tire pressure (cold) |
|---|---|---|---|
| Front | 19 x 2.5 in | 100/90-19 57V | 1.8 bar / 180 kPa / 26 psi |
| Rear | 17 x 3.5 in | 140/80 R17 69V | 2.3 bar / 230 kPa / 33 psi |

About the Triumph Scrambler 400 X / XC
Triumph launched the Scrambler 400 X for 2024 as part of its 400-class Modern Classics range. The Scrambler 400 XC joined it later, with availability beginning in 2025 in markets including Australia and as a 2026 model in North America.
The X and XC use the same 398 cc single-cylinder, four-valve, liquid-cooled TR-series engine, six-speed gearbox, slip/assist clutch, and chain final drive. Triumph also kept the same frame, 43 mm inverted Big Piston fork, preload-adjustable rear shock, and braking hardware.
The shared DOHC engine has a finger-follower valvetrain with DLC-coated components. Both models therefore have the same 32,000 km (20,000 mile) valve-clearance interval and use the same fluids, filters, spark plug, and scheduled checks.
Both 400s use traditional details such as a finned cylinder head and exhaust-header clamps alongside an upswept silencer. Their styling follows the larger Street Scrambler and Scrambler 1200.
The Scrambler 400 X is the more road-focused version. The XC adds side-laced spoked wheels, a colour-matched high front mudguard and flyscreen, handguards, engine bars, an aluminium sump guard, and a headlight grille. These parts improve protection and repairability on rough roads, but they do not change the engine or chassis service schedule.
Both models have the same upswept silencer and exhaust layout.
The main maintenance-specific difference is the XC’s spoked wheels. Inspect its spokes for damage and tightness when checking the wheels; the X has cast-aluminium wheels.
Both motorcycles use tubeless Metzeler Karoo Street tires on 19-inch front and 17-inch rear wheels. The tire sizes, pressures, and chain-adjustment specifications are the same.
Both use a non-adjustable 43 mm inverted Big Piston fork and a preload-adjustable rear shock, with 150 mm (5.9 in) of travel at each end.
Both have switchable traction control and ABS. The XC also has a dedicated off-road ABS mode that disables rear-wheel ABS intervention on loose surfaces.
The Scrambler 400 X and XC share the TR-series engine and instruments with the Triumph Speed 400, but the two Scramblers share their own chassis, suspension, final-drive ratio, and maintenance specifications with each other.
Manual for the Triumph Scrambler 400 X / XC
The maintenance schedule above comes from Triumph’s owner handbook for the Scrambler 400 X. Triumph gives the Scrambler 400 XC the same 16,000 km (10,000 mile) / 12-month service interval, and the XC shares the mechanical parts that determine the schedule. Triumph’s owner manuals are available on the Triumph website.
The 400 X and 400 XC schedules are the same. The Speed 400 shares the engine, but some chassis, wheel, and model-specific checks differ.




Target chain slack (max deflection): 20-30mm (0.8-1.2 in), this is wrong. the correct deflection for the scrambler 400x is 40-45mm. I was shown this in the Triumph service book at my dealer’s service center. I had my chain set at 35 mm and it stretched the chain and I had to replace it. Check with your local service center
