520 HLX2 - 120L Chain

NIBBI RACING · DRIVE CHAIN 520 HLX2 - 120L Chain Built for demanding off-road and powersports use, the NIBBI Racing 520 HLX2 Chain combines a heavy-duty 45Mn steel construction with X-ring sealing and a nickel-plated surface. With 120 links and a rated strength of 33.83 kN, it is designed to deliver consistent power transfer for compatible motorcycles, enduro bikes, ATVs and MX racing applications. Sealed Chain Design X-Ring Protection for Demanding Riding The 520 HLX2 uses an X-ring sealed construction to help retain lubrication around the chain pins while reducing the entry of dirt, dust and moisture into critical internal contact areas. 520 HLX2 X-Ring Chain Built to Handle Dirt, Load and Repeated Power Delivery Off-road riding continuously exposes the final drive to dust, mud, water and repeated acceleration loads. The sealed chain structure helps protect internal lubrication, supporting smoother and more consistent chain operation under demanding riding conditions. 33.83 kN Rated Strength Heavy-duty construction provides the strength required for compatible motorcycles and powersports applications. Always match the chain specification to the motorcycle manufacturer's requirements. Product Features Heavy-Duty Construction from the Inside Out X-Ring Sealed Design X-rings help retain lubricant around the chain pins and reduce contamination from dirt, dust and moisture, supporting consistent chain movement and service life. 45Mn Steel Construction Manufactured from 45Mn material for the strength and durability required in demanding motorcycle drivetrain applications. Nickel-Plated Surface Nickel-plated surface treatment adds corrosion protection while giving the chain a clean, performance-oriented metallic finish. 120-Link Configuration Supplied in a 120-link configuration to cover a wide range of compatible drivetrain setups. Required chain length varies by motorcycle and gearing. Smooth Power Transfer Designed to provide consistent engagement between the front and rear sprockets for reliable transfer of engine power to the rear wheel. Off-Road Ready Application Suitable for compatible off-road motorcycles, enduro machines, ATVs and MX racing setups that specify a 520-series drive chain.

Off-Road Enduro ATV MX Racing Before You Order Check More Than Engine Size Motorcycle displacement alone does not determine chain compatibility. Always compare the drivetrain specification with the original chain and sprockets. 01 · Chain Size Confirm that your motorcycle requires a 520-series drive chain. 02 · Required Link Count Check the original chain length or motorcycle specification. This product is supplied with 120 links. 03 · Front & Rear Sprockets Verify that both sprockets are designed for a compatible 520 chain. 04 · Motorcycle Specification Follow the motorcycle manufacturer's chain type, strength and final-drive requirements. 05 · Gearing Modifications Changes to front or rear sprocket tooth count can change the required chain length. 200cc–600cc Is a Reference Range The listed displacement range is a general application reference, not a universal fitment guarantee. A 600cc motorcycle does not automatically use a 520 chain, and motorcycles with similar engine sizes may use different chain dimensions or strength requirements. Always verify the original drivetrain specification before purchase. Chain Care Keep Your Final Drive Running Smoothly Regular Inspection & Maintenance Recommended Even with an X-ring sealed chain, routine external cleaning, lubrication and chain-slack inspection are still required. Use products suitable for sealed motorcycle chains and follow the motorcycle manufacturer's maintenance intervals and chain tension specifications. Installation & Safety Notice Confirm chain size, required link count, sprocket compatibility and installation method before use. Chain installation, sizing and adjustment should follow the motorcycle manufacturer's specifications. After installation, verify chain slack, alignment and secure connection before riding. Inspect the chain and sprockets regularly for abnormal wear, damage or excessive elongation.
