Don’t Destroy Your Chain Investment!
Today’s chains will give you many miles of riding use – Make sure you don’t ruin your chain investment by installing a new chain on old sprockets or vice versa. Even if the chain happens to fit onto the old sprockets, the old sprockets will make a new chain wear faster reducing the overall life of the chain. This image shows a new chain that won’t fit on the old worn sprocket. Get the maximum life out of your RK Chain by always changing the sprocket whenever you change the chain and keep up on proper chain maintenance. Never connect two different brands of chain and always use the master link specific to that chain model. Using a master link not designed for the specific chain you’re installing can cause a dangerous situation. The model of the master link must match the model of the chain. Even though pitch size is the same, actual chain specs can be very different between models.

SV530UWR Vintage Specific Sealed Chain!
is specific for vintage motorcycles requiring narrow clearance chains that came with 530 non-sealed chains. has a max width of 22.70mm making UWR ideal for British bikes such as Norton, Triumph, also Honda 1970’s CB750, CL450 etc.

SV530UWR features bright silver inner and outer side plates along with silver pins and rollers to compliment that vintage look. UWR Sealed Vintage chains are lighter than most other sealed 530 chains and the unique UW seals help reduce friction and improve chain wear-life more than 4-times when compared to non-sealed chains.

Are your chain’s pins rotating?

One of the easier ways to check and see if your chain needs to be replaced is to inspect the quad staked pins on your chain. When a chain is new all the pins will be all aligned and will be parallel. As a chain ages, loses internal lubrication and the internal components start wearing down, the pins can start rotating as seen in the image here. If you have pin rotation on your chain you should replace the chain ASAP.
As a preventative measure, frequent lubrication can delay the onset of rotated pins. For non-sealed chains, internal lubricant can be somewhat replaced by directing the l**e towards the roller and bushing areas on both sides so that the pin will be protected and lubricated. Unfortunately for sealed chains replacing the internal lubricant is not possible.

Closed End Faces the Rotation Direction!

When installing a clip-type connecting link always make sure that the closed end of the clip moves in the direction of chain rotation. This small requirement is vital to ensure a secure connection for the clip link.

Did you know that RK sealed chain clip-type connecting links have a front and a back which are meant to be installed in a certain direction? These clips have a slight bend which provides more tension on the side plate keeping the clip in place better.

You can identify which is front or back by rocking the plate on a flat surface. The clip can be installed on either side, and the clip will perform just fine; however, if you install the clip with the bend part away from the chain plate, the clip will perform much better.
