Why Knowing How to Count Motorcycle Chain Links Matters

Your motorcycle’s chain is a critical component for power delivery and rider safety. Whether you’re replacing a worn-out chain, adjusting to a new sprocket size, or performing routine maintenance, knowing How To Count Motorcycle Chain Links is an essential skill. Using an incorrect chain length can lead to poor performance, accelerated wear, or even dangerous derailment. Fortunately, this process is straightforward with the right method. Below, we break down the exact steps to measure your chain links accurately, saving you time and money at the shop.

Preparing Your Motorcycle for Chain Measurement

Before diving into the counting process, ensure your bike is stable. Park on level ground, engage the sidestand, and turn the engine off. For rear-wheel access, place the bike on a rear paddock stand. This safety step prevents accidental rolling and gives you a clear view of the entire chain. You’ll also need a pen and paper to track numbers, though this is optional for experienced riders.

Gather the Necessary Tools: Work Gloves and a Tape Measure

While counting doesn’t require specialized tools, work gloves will protect your hands from sharp chain edges. A tape measure isn’t essential for counting links themselves, but it helps if you later need to confirm the chain’s overall length against manufacturer specifications.

The Simple Step-by-Step Method to Count Links

Now, let’s focus on the core technique. There are two reliable methods: counting pin centers and using the master link method. Both yield the same result, but one might be easier depending on your chain’s condition (clean versus dirty).

Method 1: Counting Pins for Accurate Results

Identify the two metal plates (inner and outer plates) that form one “link.” The actual counting unit in the motorcycle industry is often the pin-to-pin distance. Here’s how:

1. Locate a starting pin — Choose any point where two plates meet.
2. Count outward — Move along the chain, counting every second pin (this gives you the link count). For example, every other pin equals one link.
3. Count tie — For long chains (e.g., 100–120 links), it’s easier to count in groups of 10 or 20, then add them.
4. Remove confusion — If you accidentally count every single pin, remember that one link = two pins. Your final pin count should be divided by 2 to get the link number.

Method 2: Using the Master Link for Simplicity

Master links are common on many aftermarket chains and some OEMs. This method reduces chance of error:

• Locate the master link clip or rivet point.
• Mark it as “1.”
• Count every outer plate until you return to the master link.
• Mark down the total, which equals total link count regardless of inner/outer plates.

This avoids the “two pins per link” confusion and is ideal for beginners.

Double-Check Your Work

After counting once, rotate the rear wheel so the chain moves, and count from a different starting point. A discrepancy of 1
