## 520 Chain Dimensions: Complete Size, Pitch, and Roller Diameter Guide<\/p>\n

If you ride a mid-displacement motorcycle, the **520 chain** is likely what transfers power from your engine to the rear wheel. Understanding **520 chain dimensions** helps you replace, upgrade, or maintain your drivetrain with confidence. This guide breaks down every critical measurement so you can buy the right chain the first time.<\/p>\n

### What Does “520” Actually Mean?<\/p>\n

The number **520** follows a standardized naming system. The first digit (**5**) represents the chain’s pitch in eighths of an inch \u2014 so 5\/8 inch, or **15.875 mm**. The last two digits (**20**) indicate the roller diameter and inner width. A 520 chain has a roller diameter of **10.16 mm** and an inner width of **6.35 mm**. These figures distinguish it from a 525 or 530 chain, which share the same pitch but use wider rollers and plates. That means a 520 chain is narrower and lighter, making it a popular upgrade for sportbikes and dirt bikes.<\/p>\n

### 520 Chain Size Chart and Key Measurements<\/p>\n

Below are the core specs you’ll see on any 520 chain spec sheet:<\/p>\n

– **Pitch:** 15.875 mm (5\/8 inch)
\n– **Roller Diameter:** 10.16 mm
\n– **Inner Width:** 6.35 mm
\n– **Pin Diameter:** Typically 5.08 mm<\/p>\n

– **Tensile Strength:** 7,000\u20138,500 lbs depending on the brand<\/p>\n

These numbers matter because they determine compatibility with your sprockets. A chain that’s too wide won’t seat properly, and the wrong pitch will damage teeth quickly.<\/p>\n

### 520 vs. 525 vs. 530: Why Size Matters<\/p>\n

Many riders ask whether they can swap a 520 for a 530. The answer depends on your sprockets. Since all three share the same 5\/8-inch pitch, the difference lies in **width and weight**. A 520 chain is about **25% lighter** than a 530, which reduces rotational mass and can free up a small amount of horsepower. However, a narrower chain has less tensile strength. For track bikes and smaller engines, this trade-off is worth it. For heavy touring bikes, a 530 is often the better choice. Always match your chain to your sprocket width.<\/p>\n

### Roller Diameter and Wear: What to Watch<\/p>\n

The **roller diameter** isn’t just a spec \u2014 it affects how smoothly the chain engages the sprocket. As the chain wears, the rollers and pins erode, causing the chain to “stretch.” A worn 520 chain will sit higher on the sprocket teeth, accelerating wear. Check your chain’s slack regularly and measure its length against the service limit in your manual. Replacing a chain before it damages the sprockets saves money in the long run.

### Common Questions About 520 Chains<\/p>\n

**Can I use a 520 chain on a 530 sprocket?** No. The width difference means the chain won’t seat correctly, leading to rapid wear or failure.<\/p>\n

**How many links do I need?** Count your old chain’s links, or check your owner’s manual. Most 520 chains come in 110, 112, or 120-link lengths and can be shortened.<\/p>\n

**Is a 520 chain stronger than a 530?** Not in tensile strength. The 530 wins there. But the 520 is lighter and adequate for most middleweight bikes.<\/p>\n

**How often should I replace it?** Every 15,000\u201320,000 miles<\/p>\n","protected":false},"excerpt":{"rendered":"
