Introduction

Using the correct chain size is essential for the performance, safety, and longevity of your 2025 STARK VARG EX dirt bike. The right chain ensures smooth power delivery, reduces wear on your sprockets, and helps prevent unexpected breakdowns on the trail or track. For a high-performance electric dirt bike like the STARK VARG EX, matching the chain to the bike's specifications is especially important to handle its unique torque and power characteristics.

What Chain Size Does the 2025 STARK VARG EX Use?

The 2025 STARK VARG EX typically uses a 520 chain size as its OEM specification. This is the most common size for modern high-performance dirt bikes, balancing strength and weight for optimal performance. While the 520 chain is standard, always check your specific trim or regional model, as variations can occur based on factory setup or aftermarket modifications. If you're unsure, verify by inspecting your current chain or consulting your owner's manual.

Understanding Dirt Bike Chain Sizes

The "520" in a chain size refers to two key measurements:
  • Pitch: The distance between the centers of two adjacent pins (5/8 inch for a 520 chain).
  • Width: The internal width between the inner plates (2/8 inch for a 520 chain).
Many dirt bikes, including the 2025 STARK VARG EX, use the 520 size because it offers a strong balance of durability and reduced weight, which is ideal for both electric and gas-powered performance bikes.

How Many Links Does the Chain Have?

The typical OEM chain for the 2025 STARK VARG EX comes with approximately 118 links. However, this number can vary depending on:
  • Changes to front or rear sprocket sizes
  • Adjustments to axle position for chain tension
  • Modifications to the wheelbase or swingarm
Always count the links on your current chain or refer to your owner's manual for the most accurate information.

Factors That Can Affect Chain Size or Length

Several factors can influence the ideal chain size or length for your 2025 STARK VARG EX:
  • Riding type: Motocross, trail, or enduro riding may require different setups.
  • Engine torque: The high torque of electric bikes can put extra stress on the chain.
  • Aftermarket sprockets: Changing sprocket sizes alters the required chain length.
  • Suspension setup: Adjustments can affect wheelbase and chain requirements.

How to Confirm the Correct Chain for Your Bike

To ensure you have the right chain for your 2025 STARK VARG EX, follow these steps:
  • Check the markings stamped on your current chain for size information.
  • Count the number of links, including the master link.
  • Consult your owner's manual for OEM specifications.
  • If needed, measure the pitch and width with a caliper to confirm the chain size.

When Should You Replace Your Chain?

Replace your chain if you notice:
  • Excessive stretching or kinking
  • Visible rust, corrosion, or stiff links
  • Uneven wear or damaged rollers
It's best practice to replace your chain and sprockets together to ensure even wear and optimal performance. Riding with a worn or incorrect chain can lead to poor power transfer, increased risk of chain failure, and potential damage to your bike's drivetrain.
