Can I Use Bicycle Chain Lube On A Motorcycle Chain

The short answer is NO. Generally, you should not use bicycle chain lube on a motorcycle chain. Bicycle lube lacks the high viscosity and “tackifiers” (sticky additives) designed to withstand a motorcycle’s intense heat and speed. Due to high centrifugal force, bicycle lube will instantly “fling off,” leaving your chain’s delicate O-rings unlubricated and exposed to friction. While it may work temporarily on low-speed dirt bikes or in a roadside emergency, it offers insufficient protection. If used, ride at reduced speeds and clean/relube with proper motorcycle chain wax or gear oil immediately.

Damage Caused By Using Bicycle Chain Lube

The root cause of the failure of bicycle oil on motorcycles lies in the difference in chemical composition.

Bicycle oils lack the necessary high viscosity and tackifier. Think about it, bicycles are driven by human power, slow, and generate almost negligible heat. In order to reduce the resistance when you pedal, the bicycle lubricant is designed to be very thin and light.

But unlike motorcycles, this is a high-intensity mechanical operation. Motorcycle chains are subjected to tremendous tensile and shear forces. Without the special sticky additives (I. e., tackifiers) in the special formula for motorcycles, thin bicycle oil simply cannot adhere effectively to metal surfaces. This oil film is too thin to maintain a protective layer between the metal parts of high-performance machines. The result is direct “metal-to-metal” dry grinding.

Accelerated Chain Wear

The most intuitive consequence of using the wrong lubricating oil is what our riders often call Fling-off.

Due to the lack of adhesion, the bicycle oil will be stripped by the huge centrifugal force almost instantly at the speed of thousands of revolutions of the motorcycle. This oil is designed for low-speed rotation and is simply powerless to resist this physical force.

The result is: your rear wheel hub and tire edges will be thrown all over with sludge (this thing is extremely difficult to clean), while the chain itself is dry and shiny. When a dry chain is running on the highway, the excessive heat generated by friction will drastically accelerate the chain’s lengthening and wear.

Take A Risk With The Oil Seal (O-Rings)

The core of the life of modern motorcycle chains-whether O-ring or X-ring-is the fragile rubber seals that lock the internal grease and block dust from the factory.

The thin soup and watery texture of bicycle oil provides little protection for these rubber seals in the face of the frictional heat generated by motorcycle engines. A serious motorcycle chain wax or heavy gear oil can form a barrier to maintain the flexibility of the oil seal.

Once the bicycle oil volatilizes or is thrown away, the oil seal will be directly exposed to the air and high temperature. Once the O-ring cracks due to friction and drying up, the original grease inside will be lost, and the chain will immediately appear “dead knots” (kinks) or tight points. At this stage, there is no other way but to replace the whole chain.

Exception: Low-Speed Off-Road And Roadside First Aid

In some extreme cases, bicycle oil can be used as a temporary “stop loss” means. For example, if you anchor in no man’s land, the chain is dry and rusted, and you only have 1 bottle of bicycle oil on hand, it can at least provide a temporary moisture barrier, which is better than dry grinding.

Similarly, on some very slow small-displacement off-road vehicles, because the centrifugal force is not so exaggerated, it may not be thrown away instantly. But this is by no means a long-term solution. It cannot provide sufficient protection against impact load and heat resistance in any long-distance riding.

What To Do If You Already Use Bicycle Oil?

If you slip your hands or have unknowingly added bicycle oil to the motorcycle chain, remedial measures must be taken immediately:

Control the speed: As suggested earlier, control your right hand and keep driving at a low speed. This is to minimize heat build-up and centrifugal force until you find a garage or repair shop.

Thorough cleaning: This is the point-don’t just spray a layer of motorcycle wax on it and it’s done, it’s useless. You need to use a special chain cleaner or kerosene to thoroughly wash off that thin layer of bicycle oil.

Relubricate immediately: When you wash the chain clean and wipe it dry, apply high-quality motorcycle chain wax or gear oil (such as 80W-90). Make sure it contains the necessary tackifier, so that you can keep your drive system, so that it can accompany you to run farther.
