Some lube’s better than no lube, I guess.

I know riders who ran nothing but WD40 or CRC 5.56 and never had any issues.

I personally just run motorex off road chain lube, WD40 is a solvent which can have adverse effects on seals and is designed to break down grease.

Side note... the WD in WD40 stands for water dispersant.

I guess this would depend on the type of riding. If going out for a 10 minute race on the local level....i would be fine with the WD40. For a 30 minute long ride or whatever....i would prefer to have a sticky chain lube to keep it from squeaking.

Goes on as thin as WD40, penetrates under the rollers, but then actually dries and collects no dust:

I haven’t lubed a chain in about 5 years...I got about 60 hours out of the stock chain and sprockets on my 2019 YZ450FX before I got rid of it (replaced with a 21 YZ450FX)...I didn’t do anything to the chain at all.

Hahahaha, well there you have it folks! Thanks for testing for us Titan.

I guess that's why my WD40 being a "non lubricant" works just fine.

I like tri-flow, keeps my chain and sprockets much cleaner than chain lube. I do use wd after washing for rust prevention.

I used tri-flow for kart racing and it's a great product. If I didn't use WD40 for my bikes I would definitely try out tri-flow in the dirt to see how clean it is. Based on your experience it sounds like it stays clean and that's a win win.

WD40 is solvent based, not petroleum. As soon as your chain warms up all it's doing is attracting dust. It has zero ability to penetrate and lubricate roller pins. As others have said, its great for preventing rust after washing but try and use a real chain lube/wax before riding. In comparison your chain and sprockets will last wayyyy longer as well.
Doesn't penetrate?? Have you ever used it before??

A lot of snake oil out there......

Of course it "works". I know guys that run their chain totally dry and it "works", as in the chain still pulls on the sprocket and turns the wheel. But don't you think there would be less drag and friction with a thin layer of lube between the metal contact points? In my OCD head drag and friction are the enemy of power.

Muc-Off's dry lube is very light, doesn't fling off, and doesn't attract contaminants.

For our o-ring and x-ring chains we use only WD-40. For our smaller bikes with roller chains we’ll put a shot of WD on after the bike gets washed but use Maxima chain wax for lubrication.
O and X-ring chains seal grease inside the rollers so you can get away with WD only and have a nice clean chain all the time.
Yeah, all my riding is off-road. I always get O/X-ring chains. Supposedly all the lubrication is sealed in. I WD-40 after washing the bike, just to keep the chain from rusting. I've never had a problem with my chains.

I’d say your right...but let’s be real...none of us are coming close to using all the power that these modern 250’s and 450‘s produce...and even if we did, we aren’t going to notice a little extra drag from the chain, robbing 1/100th of one horsepower.

I get the argument for chain lube but I'm OCD as well and sand blasting comes to mind when you see this. That's why I think this argument is like splitting hairs. You have WD40 that's supposedly "non lubricating" but stays clean without sand blasting the chain/sprocket, and then you have the most "lubricating" products that are a magnet for sand/dirt to sand blast the chain/sprockets. Obviously, there is no wrong choice because everything seems to work, even no lube per Titan Smile

Maxima seems to be the Vital favorite but look how much sand/dirt it accumulates:

I actually did a comparison, and ran one full life of a DID ERT3 chain using only WD, and one full life of the exact same chain using Chain Wax. Of course with the WD, you have to lube every moto as it slings off pretty quick. Final results, I got the exact same life out (measured in hours) of both chains. And of course, I use WD after every wash.

That's about as scientific as this dirt biker can get. The moral of the story though, is that I try to use chain lube, but if I have WD, i run it without any worries.
Great job!

Not that it really matters for this conversation but an FYI, solvents are derived from petroleum products...... oil and natural gas.

I use wd40 on o/x-ring chains. Works fine.

I haven't used a proper chain lube for years, only WD40. It's nice because there's no gunk build up, so it's really easy to clean.

It actually is a lubricant and does contain petroleum.

Chain lube sticks to the chain better. Use it for riding, Wd40 after washing and for the header pipe.

Another nice thing, admittedly, is that Costco sells a three pack of chain lube for $10.99. I mean WD. Wink

Excess wear or shortened chain/sprocket life, and excessive gooey mess that attracts sand/dirt. None of this with WD40.

I used to work at a motorcycle shop in my youth. A chain rep once told me to quit using WD-40 as it actually caused the chain to run hotter than if it had nothing. That's what we found from testing...that it's better with nothing than using WD40.

He didn't sell chain lube so don't think he was lying. So I never used it again.

Does it really matter that much? I doubt it.

After a wash we dry chain with an air gun then soak all metal parts down with WD40. Before the next ride I apply a coat of Maxima clean lube and wipe off the excess with a papertowel!

+1 for the Dupont stuff.

Dries well and chains last for 50+ hours if you lube every moto.
