A standard motorcycle chain<\/strong> is a type of roller chain used to transmit power from the engine to the rear wheel. It is made up of a series of links connected by pins and rollers \u2014 the links are typically made of steel, and the pins and rollers are made of hardened steel. Standard motorcycle chains are available in a variety of sizes determined by pitch, width, and plate thickness. The pitch is the distance between the centres of two adjacent pins; the width is the distance between the outside of the two outer plates; the thickness is the distance between the inner plate faces.<\/p>\n

\"standard<\/p>\n

The most common size of a standard motorcycle chain<\/strong> is 428, used on many types of motorcycles including street bikes, dirt bikes, and scooters. Other widely-used sizes include 520 and 530. Standard chains are relatively straightforward to replace and work well for riders who maintain a regular lubrication schedule. While they do not provide the sealed-lubrication advantage of O-ring or X-ring chains, they are lighter, more affordable, and the preferred choice in applications where maintenance is consistent or where chain replacement is performed frequently \u2014 such as track racing, where chains are changed every few rounds regardless of condition.<\/p>\n<\/div>\n

The table below covers the five standard non-sealed \u30aa\u30fc\u30c8\u30d0\u30a4\u306e\u30c9\u30e9\u30a4\u30d6\u30c1\u30a7\u30fc\u30f3<\/strong> sizes in our range. All five use a curled-type bushing \u2014 a bushing formed by rolling flat steel strip into a cylindrical form rather than machined from bar stock. This construction is appropriate for standard-service applications and produces a lighter chain than solid-bushing alternatives. Tensile strength values shown (kN) are measured break loads under controlled test conditions.<\/p>\n<\/div>\n

Advantages of the Standard Motorcycle Chain<\/h2>\n
\n

Standard motorcycle chains \u2014 also known as non-sealed chains \u2014 are the most widely-fitted type of motorcycle chain. They are less expensive than O-ring and X-ring chains, lighter in weight, and easier to install and maintain. For riders operating primarily on paved roads with regular maintenance habits, a standard chain is a practical and economical choice.<\/p>\n
