Why Using the Correct Chain Size Matters for Your 2018 Alta Redshift MX

Choosing the right chain size is essential for the performance, safety, and longevity of your 2018 Alta Redshift MX dirt bike. The correct chain ensures smooth power delivery, reduces wear on your sprockets, and helps prevent unexpected failures on the track or trail. Using the wrong size can lead to premature wear, poor handling, and even damage to your bike's drivetrain. For the unique electric power and torque characteristics of the 2018 Alta Redshift MX, matching the OEM chain size is especially important.

What Chain Size Does the 2018 Alta Redshift MX Use?

The 2018 Alta Redshift MX dirt bike most commonly uses a 520 chain size as its OEM specification. This is the standard size for most modern motocross and off-road bikes in its class, balancing strength and weight for optimal performance. There are no significant regional or trim variations for this model, but if your bike has been modified or you're unsure, it's always best to verify before purchasing a replacement. If you're uncertain about your current setup, check your owner's manual or inspect the markings on your existing chain for confirmation.

Understanding Dirt Bike Chain Sizes

A chain size like "520" refers to two key measurements:
  • Pitch: The distance between the centers of two adjacent pins, measured in eighths of an inch. For a 520 chain, the pitch is 5/8 inch.
  • Width: The internal width between the inner plates, measured in eighths of an inch. For a 520 chain, the width is 1/4 inch (2 x 1/8 inch).
Many dirt bikes, including the 2018 Alta Redshift MX, use a 520 chain because it offers a strong balance of durability and weight, which is ideal for the demands of motocross and off-road riding.

How Many Links Does the Chain Have?

The typical OEM chain for the 2018 Alta Redshift MX comes with 114 links. However, this number can vary depending on several factors:
  • Sprocket changes: Installing larger or smaller sprockets can require a longer or shorter chain.
  • Axle position: Adjusting the rear axle for chain tension can slightly affect the required link count.
  • Wheelbase adjustments: Modifying the wheelbase for handling preferences may also change the chain length needed.
Always verify the correct link count for your specific setup before ordering a new chain.

Factors That Can Affect Chain Size or Length

Several factors can influence the ideal chain size or length for your 2018 Alta Redshift MX:
  • Riding type: Motocross, trail, or enduro riding may require different sprocket setups, affecting chain length.
  • Engine torque: The electric motor's instant torque can put extra stress on the chain, so using the correct size is crucial.
  • Aftermarket sprockets: Upgrading to different tooth counts will often require a different chain length.
  • Suspension setup: Changes in suspension geometry can slightly alter the distance between sprockets, impacting chain requirements.

How to Confirm the Correct Chain for Your Bike

Follow these steps to ensure you get the right chain for your 2018 Alta Redshift MX:
  1. Check existing chain markings: Most chains have size and brand stamped on the side plates.
  2. Count the number of links: Lay the chain flat and count each link to determine the correct length.
  3. Reference the owner's manual: The manual will list the OEM chain size and recommended link count.
  4. Measure pitch and width: If markings are worn, use a caliper to measure the pitch (distance between pins) and the internal width.

When Should You Replace Your Chain?

Replace your chain if you notice any of the following:
  • Visible kinks, rust, or stiff links
  • Excessive stretching or sagging
  • Noticeable wear on the sprocket teeth
  • Frequent need for readjustment
It's best practice to replace your chain and sprockets together, as worn components can quickly damage new parts. Riding with a worn or incorrect chain increases the risk of breakage, poor performance, and potential safety hazards. Keep your 2018 Alta Redshift MX running at its best by choosing the right chain size and replacing it when needed.
