520 FB Chain

520 FB Chain

This is the top of the line; the strongest, most durable sealed chain that we offer

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 our 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

Recommended for applications 450cc and above

Replacement connecting link available

EU: Due to the accuracy of the cuts and the use of stronger alloyed steel, the FB has our highest tensile strength rating, nearly 3628,74 kg
