Some maintenance jobs look far more intimidating than they really are, and cleaning the front sprocket and chain on a Triumph Scrambler 1200 X is one of them. The first time you stare at all those covers and bolts, it feels like you are about to take half the bike apart. Once you have done it a couple of times, though, it becomes a relaxed half-hour job with a cup of coffee on the workbench and a very satisfying result at the end.
In this guide I walk you through exactly how I do it on my own bike: removing the three covers over the front sprocket, cleaning out the sprocket area, and then degreasing, cleaning and relubing the chain properly. If you prefer to watch rather than read, the full video is on my YouTube channel:

This article follows the same steps, with a little more room for explanations, tips and the reasons behind each step.
One quick but important note before we start: every bike is a little different. Model years, accessories and previous owners all leave their mark. Always check your own owner’s manual, and if anything described here does not match what you see on your bike, trust your own judgment. You are responsible for your own maintenance and your own safety.
Why Chain and Sprocket Maintenance Matters on a Scrambler
This particular chain has carried me over the Alps, through a proper hailstorm on the Col du Galibier and roughly 6,000 kilometres of everything in between: fast motorway stretches, tight hairpins, wet mountain roads and a fair amount of dust and gravel. That is exactly the kind of riding the Scrambler 1200 X was built for, and it is also exactly the kind of riding that puts a drivetrain under stress.
A motorcycle chain works in a brutal environment. It sits out in the open, just above the road, and catches everything the rear wheel and the front tyre throw at it: water, grit, road salt, dust and tiny stones. Mixed with old chain lube, all of that turns into a sticky grinding paste. Left alone, that paste slowly wears down the rollers, the chain links and the teeth on both sprockets.
If you want to keep riding big tours without eating a rear sprocket for breakfast, the chain needs a bit of love every now and then. The good news is that the job is simple. There is nothing complicated about it. It is simply the difference between a chain that lasts and one that does not. A well-maintained drivetrain also feels noticeably smoother on the road: cleaner throttle response, less snatch when you roll on and off the gas, and less of that gritty sound that tells you something is not quite right.
Preparing Your Triumph Scrambler 1200 X
Before you pick up a single tool, get the bike into a safe working position. Put the motorcycle on a stand and make sure it is standing securely. This is not the place to improvise with a wobbly setup on uneven ground. If your bike has a centre stand, that is all you need. If not, a rear paddock stand does the job just as well.
The key requirement is simple: the rear wheel needs to be able to spin freely. Later on you will be turning the wheel by hand to move the chain through a rag and to apply lube evenly along its full length, so the wheel must be off the ground and able to rotate without resistance.
It is also worth thinking about the floor. Chain cleaner and old chain grease will drip, and they do not come out of garage floors, driveways or carpets easily. Put down some cardboard, an old towel or a drip tray under the chain and the sprocket area before you start. You will thank yourself later.
Tools You Need to Clean the Sprocket and Chain
One of the nice things about this job is that it does not require a huge toolbox. For the Scrambler 1200 X, this is what I use:
- An 8 mm socket
- A 5/16 in socket
- A T25H Torx bit
- A chain brush
- A motorcycle chain cleaner spray
- A chain lube of your choice
- Some clean rags and something to put on the floor
The socket sizes and the Torx bit are for the various bolts on the covers around the front sprocket. The chain brush is one of those cheap little tools that makes a surprisingly big difference, because it gets into the gaps between the links and around the rollers where a rag alone never reaches. Mine is honestly just a no-name brush, and it does the job perfectly well.
For the chain cleaner and lube, I use a regular chain cleaner spray and a dry chain lube. Honestly, any decent motorcycle chain cleaner and chain lube will do the job just fine. I have linked a few products and brushes that have worked well for me in the description of the YouTube video, in case you are looking for a starting point.
Step 1: Removing the Front Sprocket Cover
We start with the front sprocket. On the Scrambler 1200 X it sits tucked away behind several covers on the left-hand side of the bike, and this is where most of the old chain lube and road dirt collects over time. To get at it, the covers have to come off one by one.
The first layer is the chrome cover. It is held in place by two bolts. Loosen both of them and remove the chrome cover. Put the bolts somewhere safe where they will not roll away.
Step 2: Removing the Rear Brake Fluid Reservoir Cover
Behind the chrome cover there is a second cover. This one protects the rear brake fluid reservoir. It comes off just as quickly as the first: loosen the single bolt and lift the cover away.
Now carefully set the brake fluid reservoir aside so it is out of the way while you work on the sprocket. Take your time here. The reservoir is part of your braking system, so handle it gently, keep it upright and avoid pulling or kinking the line. Brake fluid is also aggressive on paint, so you really do not want it tipping over. Move it just enough to give yourself access, nothing more.
Step 3: Removing the Sprocket Cover
There is one more cover sitting directly over the front sprocket. This one is held by four bolts. Loosen all four, remove them and lift the cover away to expose the sprocket.
And this is the moment of truth. When I took mine off, there was a remarkable amount of dirt and old chain lube built up in there. Looking at it, I had to admit that I probably should not be leaving this job for every 10,000 kilometres. It is a very visual reminder of how much grime a chain throws around over a few thousand kilometres, and all of it ends up packed around the front sprocket where you never see it during normal riding.
Step 4: Cleaning the Sprocket Cover
Before you get stuck in, make sure you have something under the work area so all that loosened dirt does not end up on the floor. Then start with the sprocket cover you just removed.
First, clear off the worst of the dirt by hand or with a rag. There is no point spraying cleaner onto thick layers of grime; you would just waste product and turn it into a smeary mess. Once the big chunks are gone, spray everything down with a bit of chain cleaner. That makes it much easier to get the cover properly clean, because the cleaner dissolves the old, sticky lube that has baked onto the surfaces.
Wipe it down, and the sprocket cover will already be looking pretty good.
Step 5: Cleaning the Front Sprocket
Next, clean the front sprocket itself. The approach is the same as with the cover. First clear off the worst of the dirt and old chain oil, then spray it down with a bit of chain cleaner.
For the stubborn bits, go in with the chain brush. Work around the teeth and into the corners where the grime tends to pack itself in tight. The bristles do the heavy lifting here, and a couple of passes are usually enough to loosen even the most compacted residue. Wipe everything down afterwards with a clean rag.
Step 6: Reassembling the Covers and the Brake Fluid Reservoir
Once the sprocket and cover look clean, it is time to put everything back together. Reassembly is simply the removal process in reverse: the sprocket cover with its four bolts, the brake fluid reservoir back into position with its cover and single bolt, and finally the chrome cover with its two bolts.
Make sure the brake fluid reservoir sits exactly where it was before and is secured properly. Tighten every bolt firmly and evenly, and check your owner’s manual for the correct torque values for your specific model. Before you move on, do a quick visual check that every cover sits flush and nothing is loose or rattling.
With that, the sprocket side of the job is done. Now let’s move on to the chain.
Step 7: Degreasing and Cleaning the Motorcycle Chain
Start by spraying the chain down thoroughly with chain cleaner. Work your way along its full length, turning the rear wheel slowly by hand so that you reach every link. Be generous, but aim the spray at the chain rather than at the rear tyre or the brake disc.
Most chain cleaners recommend a soak time of 10 to 15 minutes. During that time, most of the old chain lube residue liquefies and starts dripping off by itself. This is where the cardboard or drip tray underneath earns its keep, because a surprising amount of dark, oily liquid comes off the chain at this stage.
While the cleaner is working, you can use the chain brush to work out the stubborn residue. Brush along the side plates, over the rollers and into the gaps between the links. The combination of chemical soak and mechanical brushing is what gets a chain genuinely clean rather than just wiped over.
The Rag Trick for a Clean Chain
After 10 to 15 minutes and a bit of help from the chain brush, the old chain grease is well soaked and comes off easily with a rag. Here is the trick I use: wrap the rag around the chain and turn the rear wheel by hand. That way, the chain glides through the rag and basically cleans itself.
One point here is non-negotiable: always turn the wheel manually by hand. Never work on the chain with the engine running. A running engine with a gear engaged can pull a rag, a glove or your fingers into the sprocket in a fraction of a second, and the consequences can be devastating. Hand power only.
Once all the old grease is gone and the chain is clean, give it a few minutes to dry off. Chain cleaner evaporates pretty quickly, so you will not have to wait long. The chain should be dry to the touch before you move on to lubing; lube applied to a wet chain does not bond properly.
Step 8: Lubing the Chain Properly
Now for the final and most rewarding step. Spray the inside run of the chain with the chain lube of your choice while slowly turning the rear wheel by hand, so the lube is applied evenly along the full length.
Why the inside? When the bike is moving, centrifugal force pushes the lubricant outwards through the chain. By applying it on the inside, you let physics carry it into the rollers and the areas where it is actually needed, instead of flinging it straight off the outside of the chain and onto your rear wheel.
Ideally, let the chain lube sit overnight before you ride. That gives you the best result: the carrier solvent evaporates, the lube settles into place and forms its protective film, and much less of it gets thrown off the moment you ride away. It is also easier on the chain in the long run. That is why I like to do this job in the evening and ride the next morning.
How Often Should You Clean and Lube Your Motorcycle Chain?
This is probably the most common question around chain maintenance, and the honest answer is: it depends. Triumph does not give a fixed kilometre interval for cleaning the chain on the Scrambler. It is more of a rule of thumb: clean it once it looks dry or dirty.
In practice, most Scrambler and Bonneville riders land somewhere around every 500 to 1,000 kilometres, and right away after riding in the rain or on dusty, gravelly mountain roads. Water and grit wash the grease straight out of the X-ring chain, and once the protective film is gone, wear accelerates quickly.
So as a rule, the routine looks like this: clean with chain cleaner, work it in with a brush, wipe it dry and let it air out. Only then lube it, and do it sparingly. This is where many riders go wrong. It is tempting to think more is better, but too much lube just attracts more dirt. Excess lube catches dust and grit and creates exactly the grinding paste you have just worked so hard to remove. A thin, even coat is all you need.
Final Thoughts on Chain Maintenance for the Scrambler 1200 X
And that is it: sprocket cleaned, chain degreased, cleaned and freshly lubed. It is a small job, but one that makes a real difference in how long your drivetrain lasts and how smooth the bike feels on the road. For the price of a can of chain cleaner, a can of lube and about half an hour of your time, you protect a chain and sprocket set that would otherwise wear out much faster.
