D.I.D 520 ZVM2 Series X-Ring Gold Chain - 120 Links:
D.I.D has been making great performing chains for years being used on some of the fastest motorcycles in some of the largest contests like MotoGP racing. D.I.D constructed the ZVM2 Series X-Ring chain to reduce friction by creating a system that twists between side plates, instead of squashing them, for maximum power output. Four contact points on the D.I.D 520 ZVM2 X-Ring chain greatly increase sealing performance by keeping dirt out and lubrication in which gives it maximum wear resistance. The 520 D.I.D ZVM2 Series X-Ring motorcycle chain has been beefed up in tensile strength making it the ultimate chain for high-performance motorcycles. With the unique construction the D.I.D X-Ring chains are the world's lowest friction chains offering both extreme performance and unmatched wear life.

D.I.D 520 ZVMX Series X-Ring Gold - 120 Links:
D.I.D's engineers are continuously improving chain designs in order to handle the tremendous horsepower loads of today's high performance motorcycles. In developing the new D.I.D ZVM-X series, D.I.D focused on "Rigidity." Traditionally, "Tensile Strength" has been the bench-mark to indicate overall strength, but tensile strength is only a laboratory static measurement of a chain's fracture point. Rigidity, on the other hand, is the ability of a chain to withstand the forces that occur in the real world that riders experience. Increased rigidity means better power transfer from the engine to the ground, greater resistance to stretching under load, and overall improved performance that meets the demands of the current high-power bikes and the people who ride them.

Sunstar 520 Road DualGuard Sealed Chain - 120 Links:
Sunstar's heavy duty, street motorcycle chain model is the RDG series (RDG = Road Dual Guard) for 520, 525 and 530 applications. It uses Sunstar's DualGuard sealed ring street bike chain technology where the sealing ring has an 'X' shape - meaning there are two sealing points and two lubrication pools versus the one-sided, single-lip design of a standard O-ring. This sealed ring design type dramatically improves lubricity in high heat conditions while providing lower friction and longer chain life - and it is available for just about every street motorcycle on today's market. It comes in the natural color option and uses a strong rivet-type connecting link. For a higher performance road chain at a non-premium price, the Sunstar RDG answers the bell and is great for everything from everyday commuting to closed course riding.
Sunstar 520 RTG1 Works TripleGuard Sealed Racing Chain - 120 Links:
For a top of the line, premium-level roadracing chain, Sunstar offers the RTG1 series - Sunstar's highest performing roadracing chain - for 520 and 530 street applications (RTG1 = Road Triple Guard). This Works level chain features the TripleGuard sealed ring technology where there are 3 sealing lips and lubrication pools on each side of the ring to maintain top performance in high heat, extreme conditions; the TripleGuard ring type is the best for lubrication and protection. Both the 520 and 530 are available in pre-cut lengths and come in the gold color option (gold outer and inner plates). While the 520 is great for any bike 1000cc or less which already uses a 520 pitch, the 530RTG1 is suitable for the high-performance, larger displacement machines like the Suzuki Hayabusa, Kawasaki ZX-14R Ninja and others in the same class that use 530 pitch. Both options use the rivet-type connecting link and are well suited to handle the demands of the toughest racing conditions encountered on the street.
