Moose Racing 195FB120 520 FB Fine Blanking O-Ring Drive Chain 120 Links Gold

The Moose Racing 520 FB Drive Chain is the top-of-the-line sealed drive chain in the Moose Racing lineup, engineered for maximum strength, durability, and long service life. Built with Fine Blanking (FB) — an exceptionally precise manufacturing process — every link is cut to exact tolerances, resulting in a tighter, stronger plate, pin, and bushing union than standard chains.

Key Features:

• Fine Blanking construction produces perfectly cut links with tighter tolerances for greater accuracy and strength
• Highest tensile strength rating in the Moose Racing lineup — nearly 8,000 lb. average tensile load
• Chemically treated sealing rings that gain strength, reduce friction, and can be impregnated with grease via the FB process
• FB rings outperform X-rings — stronger, more durable, and with significantly less friction
• Gold outer links and rollers with silver inner plates, pins, and bushings for corrosion resistance
• 120 links — suitable for a wide range of applications (chains can be shortened to fit specific models)
• Clip-type connecting link included
• Replacement connecting link available separately
• Recommended for high-displacement applications 450cc and above

The Moose Racing 520 FB chain delivers race-proven performance for off-road and motocross riders who demand the very best in drivetrain components. The alloyed steel construction and advanced FB sealing ring technology combine to produce a chain that lasts longer and transfers power more efficiently than conventional O-ring or X-ring alternatives.
