Changing drive parts (Sprockets & Chain) requires some finesse and experience. It can also be difficult to determine when the drive parts need replacing. Having a professional mechanic take a look is always a good idea.

However through experience you’ll be able to spot the signs. So, the first thing you should be doing before “every ride” is a strong careful visual check and lube your chain. Always check you rear Sprockets bolts to insure they are all evenly tight.

The last thing you want is a chain or sprocket breaking.

Keep a eye out for following wear signals.

Replace Chain when:

 

If you notice any of the above signs it’s time to replace your drive parts. Since all of the components work in unison, it is always best to change them out in sets, including chain guide plastic parts and rollers.

The easiest way to check if your chain is worn is to measure the distance between the pins holding the chain together. This would determine if the chain has exceeded its “service limit” for stretch.

Your bike’s owner’s manual explains what the service limit will be.

If your chain is worn, then replace the sprockets, and vice versa. The chains and sprockets create a wear pattern with each other. When one component is replaced and not the others, the new component depreciates quicker because of the wear patterns developed on the other parts.

The same usually applies to chain rollers and guides. Typically these wear equally and if they go bad the chain can damage some very expensive parts such as the swing arm.

Sprockets ratios. For every 1 tooth you change on the front, it is the equivalent to changing 3-4 teeth on the rear. Creates a lower gearing ratio. … A lower gear ratio works well for Arenacross opposed to wide open desert racing.

Ride safe!
