How Long Do Motorcycle Chains Last? Average Lifespan

If you can insist on cleaning and lubricating the foundation every 500 miles, a modern high-quality oil-sealed motorcycle chain will definitely not have a problem running 15000 to 20000 miles (about 24000 to 32000 kilometers). But if you’re too lazy to maintain it at ordinary times, or if you buy a shoddy chain without oil seals cheaply, the life expectancy will plummet to a pitiful 3000 to 5000 miles. Many riders ask around “how long the motorcycle chain can last”, and the results are often confused by various ambiguous answers. In fact, the mechanical thing is to 1 a pile of rigorous data. In this article, I will directly tell you the specific life expectancy of different types of chains, and will also use the measured data to give you 1 to pick up why some chains are more durable than others. By the way, I will finally expose a super common tension adjustment misunderstanding that can instantly destroy a whole new transmission system.

Baseline: What is the life limit of a chain?

It is no exaggeration to say that the structural design of the chain directly determines how far it can run with you. In order to more accurately estimate the life of the chain when we commute to and from work or run mountains on weekends, I personally use to divide it into several categories to talk about.

The life truth of “oil seal” and “no oil seal”

The life of the oil seal chain can easily reach three times that of the chain without oil seal. Why? Because their internal pin shaft is firmly locked with the grease that comes with them when they leave the factory. However, those chains without oil seals do not have such rubber water-blocking rings at all. Metal and metal rub directly against each other, and the parts inside are soon polished. If you go to get a cheap chain without oil seal in order to save that money for parts, I dare say that before the end of this cycling season, you may have to change three new chains in a row, but you will lose a lot.

Three factors that determine the life of the “TEM”

In fact, if you want to accurately predict how long your car chain can last, you have to look at your usual riding habits. I have summed up a “TEM rule”-that is, tension (Tension), environment (Environment) and maintenance (Maintenance). These three points are the most reliable way to calculate the aging speed of your chain.

Tightness: The “Killer” Who Secretly Destroyed The Car”

You may not know that the tightness of the chain is not adjusted properly, and the speed of destroying the transmission system is faster than rusting! If the chain is stretched too tightly, the suspension 1 will be compressed every time it crosses a pothole, and the steel side plate will be pulled hard, directly exceeding its elastic limit. What if it is too loose? Every time you 1 oil, the chain will frantically beat the rear rocker arm, bringing extremely violent impact loads to the gears.

Environment: Sediment Is Simply Natural Sandpaper

If you often ride a bike on rainy days, mud or sandy roads by the sea, and don’t wash the chain after you finish, then its life span must be folded in half. The wet sand on the road will stick to the chain oil and become 1 kind of “abrasive paste” with strong wear force “. This stuff can easily wear out the fragile rubber O-ring, causing the internal grease to run out. The final result is that the chain is scrapped thousands of miles in advance.

Maintenance: The “500-Mile Rule” That Thunder Can’t Move”

If you want the chain to live long, a dedicated motorcycle chain oil every 500 miles is the bottom line. In addition, for every 1000 miles you ride, you have to give it a “deep bath” with kerosene or a safe chain cleaner to thoroughly clean up the “abrasive paste” you have accumulated.

Measured data speak: X type oil seal PK O type oil seal

When comparing O-type and X-type oil seal chains, our mechanic always mentions the problem of life. In order to find out how much difference we can make, our team conducted a special control test. We had both chains run 15000 miles in a simulated highway environment, with strict lubrication at 500 miles.

Stretch Results After 15000 Miles:

At the 15000-mile node, the stretch rate of the ordinary O-seal chain has reached 1.2 percent, which means that it has been abandoned and must be replaced immediately. But under exactly the same conditions, the stretch rate of the X-type oil seal chain is only 0.4! Its double-lip seal design abruptly keeps out the dust (100 percent physically isolated). This fully proves the 1 thing: spending an extra $40 or so on a high-end X-type oil seal chain can definitely save you hundreds of dollars in advance replacement fees.

The expert’s guide to avoiding the pit: how did you personally destroy the chain?

Pit 1: The “Death Trap” Of The Countershaft Oil Seal”

If you adjust the chain as tight as the guitar strings, the engine’s countershaft oil seal will definitely be reimbursed. Many novices who have just come into contact with car repair like to tighten the margin of the chain in the empty state. The result? You 1 sit on your ass, the rear shock absorber compresses, the rocker arm moves back, and the chain is instantly stretched to its limit. This extremely terrible pulling force will directly pull back the output shaft of the gearbox and tear the rubber oil seal inside. Remember, be sure to leave a margin of 1.2 to 1.6 inches (about 30 to 40mm) to allow some room for the suspension to float up and down.

Pit 2: Only Change The Chain And Not The “IQ Tax” Of The Tooth Plate”

The chain doesn’t work, so you only change the chain, not the front and back teeth? Congratulations, the new chain will soon be scrapped. The tooth disc and the chain will run in each other in the long-term use, forming a 1 tacit mechanical pitch. If you hang a brand new chain on an old tooth plate that has been ground like a barb, those broken teeth will force the new chain to stretch until it conforms to its own shape. Therefore, listen to the sentence: when changing the chain, remember to change the front and back discs together. this must be a “three-piece” project.

Some questions that car friends love to ask (FAQ)

How Long Can The Chain Live If It Is Never Oiled?

If you stocking it thoroughly and let it run dry, within about 1500 to 3000 miles, the chain will start to catch, rust and even knot. The severe friction caused by the lack of lubrication will bring high temperature, which will directly melt the rubber oil seal inside. Finally, there are dead chain links everywhere, and there is a danger of breaking the chain at any time, which is absolutely fatal when riding.

How To Judge The Chain Should Be Changed?

There is a very simple method: you pull the chain back hard at 3 o’clock on the back tooth plate. If you can see half of the teeth exposed, the chain is completely hopeless. There are also some obvious “signs before death”, such as “rust powder” sprayed all-red near the front tooth plate, chain links that cannot be broken straight, or the adjustment allowance on the rocker arm has bottomed out.

The Faster You Ride, The Faster The Chain Breaks?

It really is. Violent acceleration, off the track, and a long period of high-speed racing will bring extremely terrible shearing force to the chain pin. Like those “grumpy brothers” who like to give oil at the start of traffic lights, their chains wear out 20% to 30% faster than those commuters who cruise smoothly on high speed.

Is It Safe To Ride With Loose Chains?

Absolutely unsafe, even can be said to be joking with life. When driving at high speed, the loose chain is extremely easy to fall off the rear tooth plate. Once the chain is dropped, it will either pull forward like a whip to split the engine case. Or die wrapped around the rear wheel spokes, causing the rear wheel to lock up instantly, no matter what kind of consequences are unimaginable.

Can I Use WD-40 To Wash The Chain To Extend Its Life?

Here to make it clear, ordinary WD-40 mainly from the role of solvent, it is not what lubricating oil. If you use it simply to wash the mud on the chain, that’s no problem, but you must wipe it thoroughly after washing, and then spray special heavy motorcycle chain wax or gear oil to protect it. If only a layer of WD-40 is left after washing, the chain is actually dry and has no protection at all in the face of high-speed friction.
