At the beginning of the article about motorcycle chain types explained is worth to say a little about the chain drive itself, its features, pros and cons.
Today, one of the most common drives on the rear wheel, is a chain drive.
The advantages of the chain drive are obvious: High efficiency, ease of maintenance and installation, the ability to easily change the gear ratio, a relatively low cost.
There are not so many minuses, but they are: First of all, it is the need to lubricate the chain and, in the process of deterioration and stretching of the motorcycle chain, pull it in time without excessive sagging.
PITCH OF MOTORCYCLE CHAINS.
The first thing you should pay attention to is the ‘pitch’ of the motorcycle chain. Each motorcycle chain has a digital marking.
Question: What does ‘pitch’ mean in relation to a motorcycle chain?
Answer: It’s meaning on motorcycle chain the distance of between the chain pins.
Question: How many different motorcycle chain pitches are there?
Answer: They are many and many, but commonly used there are the following: 420, 428, 520, 525 & 530. The first digit represents the pitch of the chain. The second and third width of the motorcycle chain.
NUMBER OF LINKS IN THE MOTORCYCLE CHAIN.
The next thing to know is the number of links in the motorcycle chain that we need. Everything is simple. You can take our old worn chain and count the number of links or use some sites to select driving stars to see the required number of links to our motorcycle. But if the gear ratios are changed, accordingly, the number of chain links will be required, either more or less, depending on the selected driving stars.
Having dealt with the number of links and the chain pitch, we turn to the types of seals.
Question: How do I know what size of my motorcycle chain is?
Answer: You can measuring it yourself, but more easier just need to look on the side of some of the links. All most motorcycle chain brands stamp the size here.
TYPES OF SEALS FOR MOTORCYCLE CHAINS.
To begin with, the chains for motorcycles should be divided into stuffing boxes and without stuffing boxes.
Well, if the stuffing box chains are not clear, then the gland stuffing chains should be given a little more attention. It is customary to affix marking on glandular motorcycle chains depending on the type of stuffing boxes or seals. The simplest type of oil seal is the O-ring, the more advanced ones are X, W, Z-rings (they have a higher resource and fewer friction losses). The purpose of the seal of the motorcycle chain, keep the factory lubrication inside the rollers. This lubricant allows to minimize wear of pins and rollers, significantly increasing the life of the chain as a whole. To ensure that the seals of the motorcycle chain do not dry up and do not lose their effectiveness, it is necessary to regularly lubricate the motorcycle chain with special lubricants.
Looking through the history and evolution of the moto chains, it was the stuffing chains that allowed us to abandon the use of protective casings and to apply an open system, which we now see on almost all motorcycles.
Nevertheless, without glandular motorcycle chains are still used, but usually either in sports or on a little cubature technique. Especially popular are the stuffing chains and are widely used, in motocross and Hard Enduro.
LOCKS OF MOTORCYCLE CHAINS.
Locks for motorcycle chains are usually supplied complete with a chain. Therefore, there is no need to invent anything, just take and install the connecting chain lock. If we need, for some reason, a new lock motorcycle chain, then we definitely need to know the marking of the chain and under it we select a chain lock with exactly the same marking. The installation of locks with different markings is not desirable, since there can be not only different thicknesses of pins and plates, but also different steel. Therefore, to ensure that our chain does not have any weak points, we locate locks of the same manufacturer and exactly with the same marking.
AT THE END OF THE ARTICLE.
In addition to the main, above-listed parameters of the drive chains, it is necessary to take into account which technology and in what conditions the moto chain will be used. For example, if we have a powerful liter sport bike, then the need to install reinforced chains is obvious. At the same time, if we have an ordinary road bike with a capacity of up to 100 liters. Then there is no particular reason to overpay and install the most expensive chain, designed for powerful motors under 200PS.
Considerable importance is also the choice of brand. About brands, advantages and disadvantages, proper maintenance and so on. There will be the following articles, in which we will discuss in more detail the topic of motorcycle chains.
