JT 428 Series Heavy-Duty Motorcycle Chain — 132-Link Black Steel, High Tensile HDR 5,512 lbf

The JT JTC428HDR132SL is a 428-series heavy-duty black steel motorcycle chain with 132 links, built for off-road performance and reliable power transfer.

This JT HDR chain is engineered for aggressive off-road and racing use where strength, low weight and consistent power delivery matter. Constructed from high-grade special steel alloys and finished in black, the chain balances durability with minimal mass so it suits motocross, enduro, ATV and other off-road applications. It is designed to pair with JT sprockets for optimized drivetrain efficiency.

How strong and durable is this chain for off-road riding?

The JTC428HDR132SL delivers high tensile strength and a construction meant to survive tough terrain and repeated shock loads. With a rated average tensile strength of 5,512 lbf and two pin rivet presses, the chain resists elongation and wear under hard use.

• Average tensile strength: 5,512 lbf for heavy-duty resistance
• Two rivet presses per pin to improve retention and fatigue life
• Special steel alloy plates and rollers for wear resistance

What are the exact dimensions and fit details I need to know?

This 428-series chain uses industry-standard 428 geometry tailored into a 132-link length for longer rear spacing or specific builds. Key measurements let you confirm compatibility with your sprockets and swingarm setup.

• Roller diameter: 8.5 mm — compatible with 428 sprocket teeth
• Pin length: 18.3 mm and inner/outer plate thickness: 2.0 mm
• Weight: 2.14 lb per 100 links — full 132-link assembly follows this density
• Master link type: clip style for straightforward installation and removal

How does this chain affect performance and maintenance?

Designed for efficient power transfer, the JT HDR chain reduces drivetrain losses and offers predictable wear characteristics when maintained. Using JT sprockets and correct tension, riders can expect smoother throttle response and longer intervals between replacements compared with lower-grade chains.

• Optimized for power transfer when paired with JT sprockets
• Black finish helps resist corrosion and hides grime from off-road use
• Regular lubrication and tension checks extend service life in harsh conditions

Who this chain is for: The JT JTC428HDR132SL suits racers, off-road enthusiasts and mechanics building or maintaining bikes and ATVs that demand a stronger-than-standard 428 chain. It’s a practical choice when you need a longer 132-link assembly for specific swingarm lengths or customized gearing setups and want a durable, performance-focused chain to match JT sprockets.

Manufacturer specifications and tips
JT recommends using this HDR chain with matching JT sprockets to achieve the best ride feel and service life. Check your motorcycle’s chain routing and tension requirements before installation, and follow routine lubrication and inspection schedules to preserve tensile strength and wear resistance.
