This final drive chain is the correct length and pitch for standard factory fitted sprockets.

• If you have odd sprockets with fewer or more teeth than standard you will have to select equivalent pitch and suitable length from our drive chain category. Always select a longer chain if in doubt, you can then cut it down with one of our chain tools, its not so simple to add links if its too short!
• Always go up or down in even numbers of teeth as odd numbers will make selecting the length of chain to suit, much more difficult for beginers

Chain Type Guide:

• Standard chain is a regular chain used on smaller bikes
• Heavy Duty is mostly aimed for midsized road bikes, most MX bikes can run on HD chain
• O-ring is a sealed chain mainly used on large road bikes. It's also used on some MX bikes, especially for Enduro use as they retain lubrication better than HD chains
• X-ring is a step up from O-ring, they hold lubrication even longer therefore providing less friction and will last longer when compared to a matching brand. An X-ring seal has two lips to seal, to keep lube in and dirt out as it sits flat, it seals better than the O-ring seal
• The life of O-ring chain is usually determined by the durability of the O-ring. To improve the durability, there should be an oil film on the O-rings at all times. Even though it is a sealed chain, lubrication is required to extend its working life
• However, make no mistake, a more expensive O-ring chain can easily out last a cheaper X-ring chain
• We now stock the latest grades of chain including the Z-ring from WRP, UWV narrow UW-ring (Perfect for large classics), XW-ring heavy duty and super heavy duty, XSO RX-ring heavy duty all from RK Takasago Chain
