Motorcycle Chains and Sprockets Parts for the Yamaha MX250

Two of the most important components of the Yamaha MX250 are the chain and front and rear sprockets. Without them being in tip top shape, the motorcycle is unable to perform the way it is meant to. Fortunately, you can easily find chains, and sproket parts, and with good maintenance and replacement when needed will help ensure a safe, smooth, and consistent ride.

How long does a motorcycle chain and sprocket last?

The MX250 chain and sprockets last an average of 20,000 to 25,000 miles, depending on how well each is maintained. When the MX250 is new, a few adjustments may need to be made within the first 10,000 miles. When it is time for replacement, its good to replace both parts at the same time.

How do you check a motorcycle chain and sprocket?

Remove both parts from the MX250. Its good to have a second person helping with the removal so they can apply the rear brake at the moment the sprocket nut is loosened. If the motorcycle has a circlip, it will also need to be removed. Once the chain is removed from the motorcycle, you can do a visual inspection. Look for stiffness, loose rollers, and damage. The sprockets should be evaluated for rounded or pointy teeth, damage, rust, a change in shape, or anything that looks unusual.

When do you change a motorcycle chain and sprocket?

A rhythmic vibration is a sign that there may be a problem with the chain. Removing it will help you identify any problems. Some chains have a removing connecting link that can be removed using a screwdriver. Lay the part out on a table and see if it has any elasticity. If not, there is stiffness. Also evaluate the following when looking at the chain and sprockets:

  • Rollers that dont move
  • Dryness
  • Bad O-rings
  • Rounded or pointed teeth on the front or rear sprocket
  • Front or rear sprocket that is worn, rusted, or damaged
How do you change a motorcycle chain and sprocket?

Its important to change the chain and the sprockets at the same time because changing one and not the other can lead to premature wear. Although some chains have a removable connecting link, everything needs to be removed. Follow these steps:

  1. Remove the front sprocket.
  2. Remove the circlip if the motorcycle has one.
  3. Remove the chain.
  4. Remove the rear wheel to replace the rear sprocket with the new one.
  5. Install the new front sprocket but dont tighten the nut too much so the new chain can be installed.
  6. Remove links to shorten the chain to the right length if the new one is too long.
  7. Tighten the bolts.
How do you adjust the final drive of your bike?

The simplest way to adjust the final drive of the motorcycle is to get a new front sprocket, especially one with fewer teeth if you want to increase power. However, it is ideal to change both so they wear the same.
