Motorcycle chains are the unsung heroes of drivetrain performance. While we often focus on sprockets, lubrication, and tension, there's a tiny yet critical component that literally holds everything together — the chain link. But what exactly are master links, connecting links, and rivet links? And which one should you use? Let's break it down.
1. 🔗 What is a Chain Link?
Every motorcycle chain is made up of inner and outer plates joined by pins and rollers. To close the chain loop around the sprockets, a special link is used — this is where connecting links come into play. These are commonly categorized into three types:
2. 🔧 Master Link (Clip-Type Connecting Link)
The most common on off-road bikes and easy-to-install chains.
-
Design: Comes with a removable clip that slides over two pins on the outer plate.
-
Advantages:
-
Simple and quick to install/remove with basic tools.
-
Ideal for trail riders and DIY mechanics.
-
-
Disadvantages:
-
The clip can potentially come loose under high stress or poor installation.
-
-
Best for: Dirt bikes, temporary chains, or lower-powered motorcycles.
Installation Tip: Always install the clip so the closed end points in the direction of chain travel to reduce the risk of it being knocked off.
3. 🛠️ Rivet Link (Soft Link)
Common in OEM and performance-oriented setups.
-
Design: Uses pins that are riveted over on the end, forming a permanent closure.
-
Advantages:
-
Extremely secure — won’t come off under stress.
-
Recommended for high-performance or high-speed road use.
-
-
Disadvantages:
-
Requires a proper chain riveting tool.
-
Not designed for removal — considered permanent.
-
-
Best for: Street bikes, race bikes, and high-power motorcycles.
Pro Tip: If you're riding a modern sportbike or any motorcycle over 400cc, a rivet link is likely your safest and most durable choice.
4. 🧰 Do You Need a Chain Tool?
Short answer: Yes, if you're using a rivet-style link or cutting a new chain to size.
Here’s when you’ll definitely need a proper chain tool:
-
🔩 Installing a rivet link: You need a tool to press the outer plate onto the pins, and then deform the rivet tips securely.
-
✂️ Sizing a chain: Most new chains are sold longer than needed. A chain breaker tool is required to remove extra links safely.
-
🧑🔧 Professional or high-stress use: If you're working on a track bike or regularly hitting high RPMs, using the right tool ensures a stronger, safer connection.
A good quality chain tool kit usually includes:
-
Chain breaker pin
-
Press plates
-
Rivet flaring tips
-
Handle or ratcheting mechanism
Trying to install a rivet link without a proper tool can lead to a weak joint, chain damage, or premature failure, none of which you want on the open road.
5. 🧩 Other Terms to Know
-
Connecting Link: General term for any link that joins chain ends.
-
Soft Link: A rivet link, named for the way its pin heads are “softened” or flared.
-
Solid vs. Hollow Pins: Hollow pins are easier to flare when riveting, making them more DIY-friendly.
6. 🔍 Quick Reference Table
| Type | Installation | Tools Needed | Strength | Ideal Use |
|---|---|---|---|---|
| Master (Clip) | Easy | Pliers | Moderate | Dirt & trail bikes |
| Rivet | Moderate | Chain tool kit | High | Street, sport & touring bikes |
7. 🏁 Final Thoughts
Chain links might be small, but they play a massive role in keeping you rolling. Whether you’re choosing a chain, doing your own maintenance, or speccing a race bike, knowing the difference between link types and the tools required can make all the difference in both safety and performance.
