The 520 FB (Fine Blanking) Ring Chain is the strongest, most durable sealed chain Moose Racing offers. This product is the 116 link chain. It is recommended for 450cc and above.
- FB = Fine Blanking, an incredibly precise manufacturing process that yields perfectly cut links. Tight tolerances make the plate, pin, and bushing union accurate and strong
- Due to the accuracy of the cuts and the use of stronger alloyed steel, the FB has the highest tensile strength rating, nearly 8,000 lb.
- Special sealing rings are chemically treated to gain strength and reduce friction. The FB treatment allows the O-rings to be impregnated with grease. FB rings are stronger and more durable than X-rings, with significantly less friction.
- Gold links and rollers, silver inner plates, pins and bushings
- Clip-type connecting link included
- Replacement connecting link available
- The chain is available in link sizes of 100, 110, 114, 116, 120 and an M link.
