Snell & RK Chain & Sprocket Kit OR525GXW

A versatile chain & sprocket kit where you can choose the sprocket sizes yourself!

With the help of our chain and sprocket guide, you can easily find the right ones for your motorcycle. If you want the original caulking, you can choose the corresponding sprocket and chain from the list.

The sprockets:
All Snell sprockets are laser cut, unlike some other sprockets which are made by punching. In manufacturing, advanced technology is used to get the perfect cut to increase the sprocket’s durability. If your chain is well maintained, you can expect a lifetime of + 3000miles depending on the surface. All Snell sprockets have a black anodised “Electroplated” surface which gives a smooth finish and also increases the sprocket’s durability.

The chain:
RK has equipped motorcycles from ALL major Japanese motorcycle manufacturers’ factories with chains for over 40 years, providing both MotoGP and MXGP teams with first class chains!
This is RK’s high-tech GXW chain with newly developed XW rings!
High performance bikes expose the chain to extreme stress. To get maximum wear resistance against this, RK has developed XW rings to seal the lubricant by the links.

These chains offer the best features in demanding conditions and protect against high-speed wear, heat build-up, torsional flex and lubricant loss. The ring design allows the links to be sealed at 6 points. Dirt and dust, which can wear away at the links, are kept out and the lubricant stays inside. This significantly reduces the overall wear.
The XW ring shape is the best for keeping the chain lubricated under the most extreme conditions and increases the chain’s life to the maximum – up to 50% longer than an O-ring chain!

Rivet lock included.

Here’s how to choose the right sprocket and chain for you:

Changing the size of the front or rear sprocket is a very simple and popular way to change the character of your motorcycle.

1: For better acceleration, change to a smaller front sprocket and/or a larger rear sprocket.

2: To get maximum speed, change to a larger front sprocket and/or a smaller rear sprocket.

If you replace 1 tooth at the front, you will notice about the same difference by replacing 3 tooth at the rear. On most motorcycles, you notice a big difference by changing one tooth on the front sprocket, and it is recommended to start by making small changes.
To maintain the correct angle of the chain, you should fairly distribute the changes between the front sprocket and the rear sprocket. It is better to replace 1 tooth on the front + 3 teeth on the rear sprocket than 6 rear teeth, for example.

When changing the size of the sprocket, you may also need to change the length of the chain.
On almost all motorcycles, you can switch to 1 tooth larger or smaller on the front/rear sprocket, but still maintain the original length of the chain.

If you do need to change more than 1 tooth, you often need to change the length of the chain. The following is a good general rule to make use of:
If you switch to a sprocket with 2 more teeth, you will need a longer chain with 1 extra link.

Also bear in mind that all chain lengths go up in sets of 2, so you may need to cut the chain.
In some cases, you will not need to cut it and you can adjust the axle blocks on the wheel axle.

A link on the chain corresponds to an adjustment of 8-10 mm on the axle block.
If you need an extra link on the chain and have the option to adjust 8-10 mm on the axle block, you can buy a chain that is 2 links longer and avoid having to cut the chain.
