JT 428-Series Heavy Duty Motorcycle Chain 132-Link Black Steel Non O-Ring - 5512 lbf Tensile

The JT Chain JTC428HDR132SL is a 428-series, 132-link heavy-duty black steel motorcycle chain built for off-road racing and high-torque applications.

Purpose-built for MX, enduro, off-road, ATV and street motorcycles that demand durable power transfer without extra bulk, this JT HDR chain combines high-grade special steel alloys with a compact, performance-focused profile. Engineered to meet modern motorcycle standards, the chain balances tensile strength and low weight so riders get confident acceleration and dependable service life when paired with compatible JT sprockets.

How strong and durable is this JT 428 HDR chain for racing?

The chain is manufactured from high-grade steel alloys and rated to an average tensile strength of 5512 lbf, with two pin rivet presses per pin for added retention. Those design choices reduce the chance of link failure under hard acceleration and rough terrain while keeping the assembly compact and light.

• Average tensile strength: 5512 lbf for consistent load resistance
• Two pin rivet presses to improve joint security
• Inner and outer plate thickness: 2.0 mm each for balanced rigidity
• Designed for off-road racing stresses and general motorcycle use

What are the exact dimensions and weight of the JTC428HDR132SL chain?

This 428-series chain uses a standard roller size and is built to fit vehicle-specific sprockets and drivetrains that accept 428 pitch components. It lists precise roller and pin measurements so you can confirm compatibility with your bike before installation.

• Roller diameter: 8.5 mm for proper meshing with 428 sprockets
• Pin length: 18.3 mm for correct plate engagement
• Plate thickness (inner/outer): 2.0 mm each for strength and stiffness
• Weight per 100 links: 2.14 lb — useful for calculating total chain mass

Does this chain require special maintenance or sealing (O-ring)?

The JTC428HDR132SL is a non O-ring chain, so it relies on periodic cleaning, lubrication, and inspection rather than factory-sealed internals. Non O-ring chains offer lower friction and lighter weight, making them popular for racing, but they do need more frequent maintenance to keep longevity and optimal performance.

• Non O-ring design: lighter, lower friction, needs regular lube
• Recommended: clean grit and apply chain lubricant after muddy or dusty rides
• Inspect rivets and link movement to spot wear early

What type of master link does it use and how do I fit it?

The chain is supplied with a clip-style master (connecting) link which simplifies installation and removal for maintenance or replacement. Clip links are familiar to many riders and can be installed with basic tools, but ensure proper orientation and secure seating of the clip to avoid accidental disengagement.

• Master link type: clip-style connecting link for straightforward assembly
• Use correct clip orientation and confirm full engagement of link plates
• Torque and tension the chain per your motorcycle manufacturer’s recommendations

Who is this chain for? The JT JTC428HDR132SL is aimed at riders and mechanics who need a robust, race-capable 428-series chain that keeps weight down and strength high. It's a good match for off-road racers, enduro competitors, ATV users and street riders who prefer a non O-ring setup and who perform routine chain care. Pair it with JT sprockets for matched tooth profiles and maximum drivetrain efficiency, and choose the correct link count and fitment for your motorcycle model before ordering.
