Key Takeaways
- Maxima Chain Wax is the best lube for most street riders: little fling, safe on O, X and Z-ring chains and a strong all-rounder in a 55-lube test.
- Do not pack a chain with bearing grease. Motul C5 paste is the closest thing to a chain grease that works.
- 80W-90 gear oil matched the best wear result in the lab, but it flings heavily and protects poorly against rust.
- Lube every 300 to 500 miles and after every wash or wet ride, on a warm, clean chain with the engine off.
- Chain makers D.I.D and RK say not to clean sealed chains with kerosene.

The best lube for a motorcycle chain on most street bikes is Maxima Chain Wax. It sets to a soft film that stays on the chain, it is safe on O-ring, X-ring and Z-ring chains, and it was one of the strongest all-round performers in Bennetts BikeSocial’s test of 55 chain lubes. It is also widely sold, which matters when you need a can before a trip.
The right product still depends on how you ride. A sport bike at high revs needs a lube that will not fling. A dirt bike needs one that will not turn into grinding paste. A long-distance tourer may be better off with an automatic oiler. The picks below are grouped by that job, and the sections after them cover chain grease, gear oil, cleaning and how often to lube.

What a chain lube has to do
A modern sealed chain carries its own grease. O-rings, X-rings or Z-rings trap factory grease between each pin and bushing, and nothing you spray on the outside reaches it. So the lube you buy has three different jobs:
- Keep the rubber seals supple. A quoted RK representative told Motorcycle.com that lubrication keeps the seals pliable so they hold the internal grease in place. Once a seal dries and cracks, the chain is on borrowed time.
- Lubricate the parts that are not sealed. The rollers turn on the outside of the bushings and bear against the sprocket teeth, and they depend entirely on the lube you add.
- Stop rust on the side plates and rollers.
That explains why the choice comes down to how well a product stays put. Almost every lube sold for motorcycles is safe on seals. In the BikeSocial test, O-rings sat submerged in each product for four weeks and the author reported no swelling, hardening or cracking. The real differences are fling, grit and how long the film lasts.
Wax, spray, dry lube or oil?
Chain lubes fall into six groups. Pick the group first, then the product.
| Type | Works best for | Advantage | Drawback |
|---|---|---|---|
| Wax spray | Most street riding | Very little fling, stays on in rain | Hardens if left too long; hard to see on the chain |
| Tacky spray | Sport bikes, fast road riding | Strong film at high speed | Sticky film holds dust and grit |
| Dry lube | Dust, sand, riders who hate cleaning wheels | Almost no residue | Lighter film; reapply more often |
| Paste | Riders who want precise, spray-free application | No overspray, thick film | Slower to apply |
| Gear oil | Budget riders, frequent lubing | Lowest cost, excellent wear results | Flings heavily, weak rust protection |
| Chain oiler | Touring and high mileage | Lubes every mile without you | Fitting time, oil on the rim if set too high |
Best grease for a motorcycle chain
You should not pack a motorcycle chain with bearing grease. The grease that matters is already sealed inside the chain, and a thick grease smeared on the outside cannot get past the seals. It sits on the plates, picks up road grit and turns into an abrasive paste, and it softens and throws off when the chain gets hot.
When riders search for chain grease, they usually want one of two things, and both exist in a form that works:
- A brush-on paste. Motul C5 Chain Paste is the closest thing to a true chain grease. It comes in a tube with a built-in brush and goes exactly where you put it.
- A spray grease. Tacky aerosols such as Motul C2 and Bel-Ray Blue Tac go on thin so they can creep between the side plates, then thicken into a grease-like film as the carrier evaporates. Bel-Ray says Blue Tac sprays on thin for that reason.
Older non-sealed chains are different, since they have no factory grease inside at all. They need a thin, penetrating lube that reaches the pins, and they need it often. Thick grease is the wrong answer there too.
What the lab tests show
Few chain lube tests measure anything. Most roundups repeat product descriptions. The BikeSocial test is the most useful public data because it measured fling at 1,100 rpm, corrosion on coated discs, stickiness and how easily each product cleaned off. Ten lubes plus gear oil, chainsaw oil and Scottoil also went to a lab for four-ball wear and extreme-pressure weld tests.
The results that matter for buyers:
- Maxima Chain Wax performed well across the board, with the warning that it hardens if left on too long.
- Gear oil matched the best product in the wear test, but flung heavily and protected poorly against corrosion.
- XCP scored at the top for wear and S100 White Chain Spray led the sprays for extreme pressure. Neither is easy to buy on Amazon in the US, which is why they are not on this list.
- Muc-Off’s Dry Weather lube did poorly on wear. Wurth’s dry lube was among the least sticky but also scored poorly in wear and weld tests. Dry lubes keep a bike clean at some cost in film strength.
- Scottoil scored lower on extreme pressure, which matters less in an oiler that replenishes the chain constantly. Oilers keep rollers wet but do not coat the outer plates, so those can still rust.
The test named no overall winner, and the author points out that no industry standard exists for chain lubes. Older comparisons such as webBikeWorld’s spray-off were subjective ratings of fling and stickiness, useful only as rider opinion.
The 10 best lubes for a motorcycle chain
1. Maxima Chain Wax
Best lube for a motorcycle chain overall
Maxima Chain Wax goes on wet and sets into a soft paraffin film that resists fling. It is the one mainstream product that came out of the BikeSocial test as a strong all-rounder, and Maxima rates it for O, X and Z-ring chains in wet and dry conditions.
The main thing to watch is buildup. Left for months, the wax hardens on the plates and takes more effort to clean off, so this suits riders who lube on a schedule. Give it 10 to 15 minutes to set before riding. It is also hard to see once it dries, so go by mileage instead of looks.
- Works for commuting, touring and weekend riding
- Very little fling on the rear wheel
- Sold in a combo with Maxima Clean Up if you need a cleaner too
2. Motul C2 Chain Lube Road
Best chain lube for street and sport bikes
Motul designs C2 for street bikes and fast bikes in particular, and it is rated for O, X and Z-ring chains. The red straw puts the spray exactly where you aim it. Its film is tackier than wax, which suits a chain running at high speed.
Motul asks you to spray the whole inner length of the chain on a clean chain and let it settle for a few minutes. The tacky film will collect dust on dirt roads, so keep it on the pavement.
- Good choice for sport and naked bikes
- Precise straw limits overspray on the rim
- Available in a kit with C1 cleaner, brush and gloves
3. Motul C5 Chain Paste
Best grease for a motorcycle chain
C5 is what chain grease should be: a thick paste in a tube with a brush at the tip. There is no aerosol, so nothing lands on the tire, the brake disc or the garage floor. It is rated for O, X and Z-ring chains and sticks to the plates once applied.
It takes longer than a spray because you work link by link, but you use very little. It also travels well, since a tube is safer in a tank bag than an aerosol can.
- No overspray near the rear brake
- Good for apartment riders who cannot spray in a shared garage
- Small tube fits a tool roll on long trips
4. DuPont Chain-Saver
Best dry chain lube
Chain-Saver is a wax-based lube with Teflon and moly that goes on wet and sets to a dry film. DuPont sells it as O-ring safe, dirt resistant and non-staining with no fling-off. webBikeWorld’s review found that it only partly dries, so treat “dry” as a relative term. It still suits a rider who hates scrubbing the rear wheel.
It is thinner than a wax like Maxima, so plan on lubing more often. It also suits dusty gravel roads, where a tacky film would collect grit. Hold a rag behind the chain, since that review also noted heavy overspray.
- Good choice for bikes with spoked or light-colored wheels
- Non-staining film
- Reapply after rain
5. Maxima Synthetic Chain Guard
Best chain lube for rain and commuting
Chain Guard is the wetter sibling of Chain Wax. It uses the same corrosion and friction additives pitched at all chains and all weather, but in a synthetic spray that does not set up firm. That makes it easier to refresh on a commuter that sees rain every week, because you never have a hardened layer to remove.
Maxima describes fling as minimized instead of eliminated, and that is the trade. Expect a little more residue on the rear wheel than with Chain Wax.
- Rated for O, X and Z-ring chains on road and off-road bikes
- Easy to top up between cleanings
- Pairs well with a monthly wipe-down
6. Muc-Off All-Weather Chain Lube
Best chain lube for checking your coverage
Muc-Off adds a UV dye to this synthetic lube, so a UV light shows exactly which links you missed. That sounds like a gimmick until you remember the biggest weakness of waxes and dry lubes: you cannot tell if they are there.
Muc-Off’s Dry Weather formula did poorly in the BikeSocial wear test. This All-Weather spray is a different formula, so that result does not carry over, but buy it for the dye and not on the strength of test data.
- Useful for new riders learning how much to apply
- Synthetic film for mixed weather
- Check coverage in a dark garage
7. PJ1 Blue Label
Best clear chain lube
PJ1 Blue Label is a petroleum-based lube that goes on clear, which keeps a gold or polished chain looking clean. PJ1 markets it for sealed chains, with penetration to keep the O-rings moist and a formula that repels water.
A clear film suits a clean custom or a classic, where a white wax would stand out on the chain. The 13-ounce can suits regular use, and a 5-ounce can fits a saddlebag.
- Clear film on gold chains
- Formula repels water and resists rust
- Two can sizes
8. Motorex Chain Lube 622 Offroad
Best chain lube for dirt bikes
Dirt changes the priorities. A tacky road lube traps sand, and that sand grinds the rollers and sprocket. Motorex 622 Offroad is a clear, fully synthetic lube tested for O and X-rings and sold specifically for off-road use.
On a dirt bike or dual sport, the routine matters as much as the can: wash, dry, then lube after every muddy ride. Keep the pressure washer away from the chain, since a hard jet at close range can push water past the seals.
- Clear film for enduro and motocross
- Large 500 ml can for frequent lubing
- Reapply after each wash
9. Valvoline 80W-90 Gear Oil
Cheapest chain lube per mile
A quart of gear oil and a cheap paintbrush will lube a chain for years. Gear oil matched the top result in the BikeSocial wear test, and Honda’s CB300F owner’s manual lists SAE 80 or 90 gear oil as the fallback when O-ring chain lube is not available.
The cost is mess. It flings heavily and it gave poor corrosion protection in the test, so it suits a rider who lubes every few hundred miles and wipes the wheel afterward. Apply a thin coat, wipe off the excess and keep it away from the tire. Any 80W-90 will do; Valvoline’s is simply easy to find.
- Lowest cost of any option here
- Strong wear protection
- Needs frequent application and a wipe-down
10. Scottoiler vSystem
Best chain oiler for touring
A Scottoiler uses engine vacuum to drip oil onto the rear sprocket while the engine runs, so the chain gets a small dose every mile. Scottoiler says the included 250 ml bottle lasts about 5,000 miles. For a rider covering 400 miles a day on an adventure bike or tourer, it removes the nightly lube stop.
An overly high flow setting leaves oil on the rim. The oil is thin, so it picks up less grit, but it leaves the outer plates less protected, as BikeSocial noted. Spray the plates with a little lube before winter storage. Scottoil refills are sold separately.
- Runs only with the engine on
- Thin oil picks up less grit than a tacky spray
- Also works in rain, when spray lubes wash off
Best lube for motorcycle chain: what Reddit riders say
Reddit has no single favorite. We read 175 comments from 88 r/motorcycles threads about chain lube, and riders argued about method far more than brand. Few comments named a product, so treat these as recurring opinions, not a ranking:
- Kerosene is the longest-running fight. It came up in 11 comments. Some riders clean with a kerosene rag and report no trouble, and others point straight to D.I.D’s warning against it. The chain maker’s instruction is the safer one to follow.
- Gear oil is the budget answer. Riders suggest 80W-90 as a far cheaper substitute for canned lube, applied every so often to keep the outside of the chain clean.
- Motul gets credit for low fling. One rider reported zero fling from Motul’s road lube after heavy fling from another brand. One KTM owner says the bikes suggest Motorex and found it a little thin.
- Sealed chains need less than the internet suggests. One rider reports passing 30,000 miles on a chain with only occasional wax, and others call daily cleaning overkill. Others lube every 1,000 km as a firm rule.
- Spray onto a brush. Some riders spray lube on a small paintbrush and paint the chain to cut overspray, which is a useful trick with any aerosol.
How to clean and lube a motorcycle chain
Lube on a dirty chain mostly glues grit in place. A full clean and lube takes about 20 minutes with the right setup.
- Lift the rear wheel. A rear paddock stand lets you spin the wheel by hand. Without a center stand or paddock stand, work on a section, then roll the bike forward.
- Warm the chain. Ride a few miles first. RideApart’s Dr. Moto advises lubing while the chain is warm after riding, and never with the engine running. Warm, not hot enough to burn you.
- Protect the rear wheel. Put cardboard on the floor and hold a rag or sheet behind the chain, so nothing reaches the tire or brake disc.
- Clean it. Spray an O-ring safe cleaner such as Motul C1 and work it with a three-sided chain brush. Do not use a wire brush.
- Dry it. Wipe the chain with a soft cloth, then turn the wheel and wipe again until the cloth stays mostly clean. D.I.D recommends a full wipe and dry every 300 miles.
- Apply the lube. Spray a thin line on the inside of the lower run while turning the wheel, aiming at the rollers and both rows of seals. One or two turns of the wheel is enough. Motul’s instructions call for the inner length of the chain, and rotation carries the lube outward.
- Let it set. Give most sprays 10 to 15 minutes before riding, then wipe off drips.
How often should you lube a motorcycle chain?
Every 300 to 500 miles is the standard answer, and more often in rain. The sources line up closely:
| Source | Interval |
|---|---|
| D.I.D | Lube every other use; wipe and dry every 300 miles |
| Honda CBR1000RR manual | Every 500 miles, or sooner if the chain looks dry |
| RideApart | About every 500 miles, more in rain, dust or mud |
Lube after every wash and after any wet ride, since water strips the film. Sealed chains forgive a missed interval better than old roller chains. In that same Motorcycle.com piece, RK puts typical sealed chain life at about 20,000 miles and unsealed at about 3,000, and bad maintenance eats into that number quickly. Good lubing also protects the sprockets, which cost more than the can. Chain care is a small part of the running costs we compare in our list of high-maintenance motorcycle brands.
What not to use on a motorcycle chain
- WD-40. Regular WD-40 is a water displacer, not a chain lube. RK tells riders not to clean sealed chains with it, though Motorcycle.com’s John Burns admits to spraying it for rust and riders argue about it endlessly. It will not replace a real lube either way.
- Kerosene. D.I.D says not to use it, warning that it can deform seal rings, and RK agrees. Some Yamaha manuals still recommend it for cleaning. With O-ring cleaners this cheap and easy to find, follow the chain makers.
- Gasoline, thinners and brake cleaner. D.I.D rules out volatile solvents, steam and wire brushes.
- Engine oil. It flings off fast, and some Yamaha manuals warn against it for sealed chains.
- Chainsaw bar oil. It is designed to stick, but in the BikeSocial lab work it trailed gear oil overall.
- Household spray lubes and silicone. Honda warns that chain lubes not made for motorcycle drive chains may contain solvents that damage O-rings. Check for an O-ring rating on the label.
Check chain slack while you are there
Lubing is the natural moment to check tension. RideApart’s rule of thumb is three-quarters of an inch to one and a quarter inches of vertical movement midway between the sprockets, measured at the tightest spot on the chain. Your swingarm sticker or manual has the exact figure, so use that first. Spin the wheel and test a few points, since chains wear unevenly. A chain that is too tight strains the output shaft bearing and is worse than one a little loose.
D.I.D sets the wear limit at 1% stretch for sealed chains, and it says to replace the chain and sprockets together. If rust, stiff links or missing X-rings show up, that is the time for a new set. If you change sprocket sizes during the swap, our gear ratio calculator shows what the change does to cruise rpm and speedometer reading.
Does your bike need chain lube at all?
Only chain-drive bikes do. Shaft-drive bikes such as the Moto Guzzi twins use gear oil in a sealed final drive, and most modern Harley-Davidsons run a toothed belt that must stay free of lube. Spraying chain lube on a belt only collects dirt. Chain-drive bikes need the routine above, which is worth counting when you compare low-maintenance motorcycle brands. While you have the rags out, our guide to the best scratch remover for motorcycles covers the tank and fairings.
FAQ
What is the best lube for a motorcycle chain?
Maxima Chain Wax is the best choice for most street riders because it resists fling, works on all sealed chains and performed well overall in BikeSocial’s test of 55 lubes. Motul C2 suits sport bikes, and Motorex 622 Offroad suits dirt bikes.
What is the best grease for a motorcycle chain?
Motul C5 Chain Paste is the best grease-style product because it is made for chains and applied by brush. Avoid regular bearing grease: it cannot reach the sealed factory grease and it traps grit on the outside of the chain.
Is gear oil good for a motorcycle chain?
Yes. 80W-90 gear oil gave excellent wear results in lab testing, and Honda manuals such as the CB300F’s list SAE 80 or 90 gear oil as a fallback for sealed chains. It flings heavily and gives weak rust protection, so apply it thin and reapply often.
Is chain wax better than chain lube?
Chain wax is a type of chain lube. Wax flings less and leaves a cleaner wheel. Tacky sprays give a thicker film for high speed. Most street riders do better with wax, and wax is the better choice if you dislike cleaning the rear wheel.
Can I use WD-40 on my motorcycle chain?
Regular WD-40 is not a chain lube, and RK advises against cleaning sealed chains with it. It is fine for loosening rust on a tool, but it does not replace a lube rated for O-ring chains.
Should I lube a motorcycle chain hot or cold?
Lube it warm, after a short ride with the engine off. A warm chain takes lube into the rollers and seals more easily. Wait until it is cool enough to touch safely, and let the film set before you ride.
Should I spray the inside or outside of the chain?
Spray the inside of the lower run, aiming at the rollers and both sets of seals. The rotation of the chain moves lube outward toward the plates. Avoid spraying the rim, tire or brake disc.
How long does chain lube need to dry before riding?
Most sprays need 10 to 15 minutes. Motul C2 settles in a few minutes and Maxima Chain Wax needs a bit longer. Lubing after your last ride of the day gives any product the time it needs.
Do X-ring chains need different lube?
No. Any lube rated for O-ring chains is also safe on X-ring and Z-ring chains. All 10 picks in this guide fit sealed chains.
Can you over-lube a motorcycle chain?
Yes. Extra lube does not protect the chain any better. It flings onto the wheel and catches grit. Apply a thin line, wipe off anything that drips and leave it there.
