Thsakzo Motorcycle Chain Breaker & Rivet Tool Kit — 15‑Piece, Fits #25–#630 Chains, Portable Case

Thsakzo's 15-piece chain breaker and rivet tool kit is a compact, all-in-one solution for splitting, removing, and reconnecting chains from #25 up to #630 on motorcycles, ATVs, dirt bikes, and bicycles.

This portable kit bundles a precision-engineered chain press, three pin sizes, two press plates, a lever and handle, plus a durable blow-molded case so you can perform chain maintenance at home or roadside. Built with a fine-thread drive screw and centering features, the tool minimizes lateral movement of pins to avoid bending or damaging side plates while pressing pins in or out. The included instructions outline correct pin protrusion and safe operation so you get reliable results without specialized shop equipment.

How does this kit work to remove and rivet chain pins?

The tool uses a threaded drive screw and interchangeable pins to push chain rivets out or press them back in. A spring and hollow rod assembly sets the pin depth and support while the press plates keep the chain aligned, producing straight, controlled motion during operation.

• Set pin protrusion to 5 mm (0.2") to avoid pin bending.
• Use the correct pin diameter (2.2, 2.9, 3.8 mm) for your chain pitch.
• Position press plates to support side plates during pressing.
• Tighten the hex bolt progressively for smooth pin movement.

Which chain sizes and vehicles does this tool support?

This kit covers a broad range of chain pitches, from small bicycle chains up to heavier motorcycle and ATV chains. The three pin sizes and adjustable press components make it compatible with most common chain types used in recreational and commuter vehicles.

• Compatible with #25 through #630 chain sizes.
• Suitable for motorcycles, ATVs, dirt bikes, and bicycles.
• Includes three pin diameters to match different rivet sizes.
• Portable case for field or garage use.

What parts come in the 15-piece kit and how durable are they?

The set includes the main tool body, a drive handle, lever, spring, two press plates, three pin sizes, and small fittings to adapt to different chains. Components are machined for concentricity and stored in a blow-molded case to protect threads and pins when not in use.

• Main tool body with precision thread drive screw.
• Handle, lever, and spring for controlled operation.
• Two press plates and three pin sizes (2.2, 2.9, 3.8 mm).
• Blow-molded carry case for organized transport and storage.

How do I avoid common mistakes during use?

Over-driving the pin is the most frequent error—set the pin extension to about 0.2" (5 mm) before applying pressure to prevent bending or breakage. Also ensure the chain and press plates are perfectly aligned so the pin moves straight through the rivet without stressing side plates.

• Verify pin diameter matches chain rivet size before use.
• Set pin protrusion to 5 mm and tighten gradually.
• Keep chain centered between press plates for straight movement.
• Replace worn pins to maintain clean, repeatable results.

Who is this for? Home mechanics, motorcycle and ATV owners, cyclists, and small workshop operators who want a cost-effective alternative to shop service will find this Thsakzo kit useful. It’s aimed at anyone who performs routine chain maintenance or needs a reliable field tool for cutting and reconnecting chains without specialized equipment. If you value portability, a broad compatibility range, and precision-threaded operation to protect chain side plates, this 15-piece set offers the essential parts and instructions to get the job done safely and cleanly.
