How to Choose a Motorcycle Chain Breaker and Riveting Tool

Replacing a motorcycle chain requires one essential tool: a chain breaker and riveting tool. A good one presses out the old chain, installs the new one and rivets the master link cleanly - without damaging the chain. This guide explains how to choose a quality chain breaker and riveting tool, and what makes the difference between a workshop-grade tool and a cheap one.

What a Chain Breaker and Riveting Tool Does

• Breaks the chain - presses out the pin to remove links or remove the old chain.
• Presses the master link - seats the side plate onto the master-link pins.
• Rivets the link - flares the rivet head so the link cannot come apart in use.

Key Features to Look For

1. Hardened Press Pin

The press pin is the part that pushes the chain pin out. On a quality tool it is hardened steel; on a cheap tool it bends on the first chain. Look for heat-treated carbon or alloy steel construction.

2. Strong Press Plates and Frame

The frame must stay rigid under load. A cast or heavy steel frame is much better than a stamped one.

3. Multiple Pin Sizes

Chains use different pin diameters. A good kit includes replacement pins (commonly 2.2mm, 2.9mm and 3.8mm) so it works across chain sizes.

4. Riveting Capability

Not all chain tools rivet - some only break. If you install chains, you need a tool that also presses and flares the rivet link.

5. Wide Chain Size Coverage

The most useful tools cover the common motorcycle sizes (420 through 630), so one tool handles most bikes in your workshop.

How to Choose the Right Size

• 420 / 428 chains - small-displacement bikes and mopeds; a compact breaker works.
• 520 / 525 / 530 chains - the most common street and sport bike sizes; a heavy-duty breaker + riveter is recommended.
• 630 chains - large cruisers; use a heavy-duty kit rated for 630.

Common Mistakes to Avoid

• Grinding the rivet head off instead of using the proper breaker - this damages the chain.
• Using an under-sized tool - the press pin bends and the link is ruined.
• Not flaring the rivet enough - the master link can separate at speed.
• Over-flaring the rivet - the link binds and wears the sprocket.
