RK GB420MXZ-108: Lightest Non O-Ring MX Chain
The GB420MXZ chain from RK Racing Chain targets serious motocross racers seeking a balance of lightness and strength. It is a non O-ring design featuring chrome-moly steel construction, seamless rollers, and oversize alloy pins to enhance durability. The chain benefits from RK’s HIT heat-induction transfer process, designed to maintain lubrication and performance under high-stress MX conditions. Ideal for riders prioritizing weight savings without sacrificing reliability on aggressive tracks.
Key considerations: non-O-ring designs typically require more frequent lubrication and may wear faster in muddy or wet environments. This chain is best paired with similarly tuned drivetrains and proper maintenance schedules to maximize longevity.
NICHE 520 Drive Chain 108: O-Ring Durability
NICHE’s 520 Drive Chain with 108 links uses O-rings (NBR) to sealing lubrication and protect against dirt and moisture. It features quad-riveted pins and is designed to last 3 to 5 times longer than many non-O-ring chains in challenging conditions. Suitable for a wide range of environments, this chain is engineered to maintain smooth operation in wet, muddy, or dusty settings while delivering reliable power transfer for street, ATV, and dirt bike applications.
Considerations: O-ring chains typically require compatible sprockets and regular maintenance with appropriate chain oil to maximize life. The 520 pitch aligns with many mid-displacement bikes, making fitment important to verify.
NICHE Gold 420 X-Ring 108: Premium X-Ring Performance
The NICHE Gold 420 X-Ring chain emphasizes ultra-high performance with premium X-rings that reduce friction and extend seal life. The 108-link length suits many 420-pitch setups, and the master link simplifies installation. Built for riders demanding peak performance in harsh environments, this chain maintains lubrication under wet, muddy, or dusty conditions, supported by quad-riveted pins and hardened steel components.
Considerations: X-ring designs generally deliver lower friction and better seal retention but can come at a higher initial cost. Ensure compatibility with your bike’s chainring and sprocket set to maximize benefits.
DID 520VX3 Gold X-Ring 108: Direct Energy Transfer
This DID 520VX3 chain features a gold X-ring design with Direct Energy Transfer technology to improve throttle response and rigidity. The 108-link length makes it compatible with many street and off-road motorcycles up to 800cc. The chain emphasizes advanced seal performance via enhanced X-ring retention along with durable pins and hardened steel components. It is positioned as a high-performance option for riders who demand precise power delivery and longevity in demanding MX and adventure riding contexts.
Considerations: Direct Energy Transfer is designed to optimize power transfer; regular maintenance and correct lubrication remain essential for sustained performance. Check sprocket compatibility to ensure even wear and smooth shifting.
NICHE 525 Drive Chain 108: Strong O-Ring Chain
The NICHE 525 Drive Chain uses an O-ring sealed design with 108 links and a 525 pitch. It incorporates NBR O-rings, master connecting clip, and LT-001A high-temperature chain oil. The chain is engineered to last 3 to 5 times longer than non-O-ring chains, with a tensile strength rated at 37.8 KN (8498 lbf). Built for wet, muddy, or dusty environments, it combines quad-riveted pins with hardened steel components for robust performance in diverse riding conditions.
Considerations: The 525 pitch is larger than 420 or 520 designs, so ensure your chain and sprockets are matched to your bike’s specifications. O-ring chains provide longevity but may require slightly different maintenance routines compared to non-O-ring designs.
Buying Guide: Key Considerations For 108-Link Chains
Riding Style And Terrain
MX, off-road, and street riding place different demands on a chain. Non-O-ring chains are lighter and can offer slightly lower friction, which some riders value on pure performance tracks. O-ring and X-ring variants excel in dusty, muddy, or wet environments where seal integrity and lubrication retention matter most. Consider your typical riding conditions when choosing between 420, 520, or 525 pitch chains and 108 links.
Chain Type And Seals
Non-O-ring chains deliver weight savings but require more frequent lubrication and cleaning. O-Ring and X-Ring chains seal lubrication longer, reducing wear in tough conditions. X-Ring chains generally provide the lowest friction and best seal retention, with high-performance variants aimed at racing and aggressive riding. Match chain type to your bike’s sprockets, maintenance habits, and budget.
Durability And Tensile Strength
Higher tensile strength often correlates with more robust construction and longer life, especially under high-torque conditions. Do not focus on tensile strength alone; consider the chain’s overall build (pins, bushings, heat treatment) and how it handles your engine displacement and riding style. A well-matched chain and sprockets combination minimizes wear and protects other drivetrain components.
Lubrication And Maintenance
Regular lubrication and cleaning extend chain life and performance. O-ring and X-ring chains benefit from proper application of high-temperature chain oil designed for sealed chains, while non-O-ring chains require timely lubrication and more frequent inspection for stretch and wear. Always follow manufacturer guidance for lubrication intervals and torque settings for the master/link.
Compatibility And Installation
Verify chain pitch, link length, master link type, and compatibility with your sprockets and front chainring. Installing a chain that doesn’t match the bike’s drive configuration can cause premature wear, poor shifting, or drivetrain damage. If unsure, consult a professional mechanic or reference your bike’s service manual for recommended chain specifications.
Maintenance Accessibility
Some chains offer easier installation with clip-type master links, while others rely on rivet-style joining links. Clip master links simplify on-trail adjustments, making field maintenance more convenient. Consider how often you expect to adjust or replace your chain when evaluating the overall ownership cost and downtime.
Cost vs. Value
Premium O-ring and X-ring chains typically cost more upfront but deliver longer life and better performance in challenging environments. If your riding involves frequent water, mud, or dust exposure, investing in a higher-quality chain can reduce long-term maintenance and replacement frequency, offering better value over time.
Across these five options, riders can prioritize a balance of weight, durability, and maintenance needs. For MX-focused sessions or track days, the RK GB420MXZ-108 and DID 520VX3 Gold X-Ring 108 provide strong performance characteristics. For riders facing tougher weather or terrain, NICHE 520 and NICHE 525 series offer robust O-ring designs, while NICHE Gold 420 X-Ring 108 emphasizes low-friction, premium sealing. Ensure your sprockets and chainring match the chosen pitch and link count for optimal operation.
