At DMG Motorsports, we present the D.I.D 525ZVM-X2 S&S-120ZB — a 120-link, silver-on-silver drive chain built for riders who demand serious strength and durability from their heavyweight, high-torque machines. As the flagship evolution of D.I.D's renowned ZVM-X lineup, the ZVM-X2 is engineered to handle the punishing power delivery of today's large-displacement sportbikes and adventure machines without missing a beat. Whether you're upgrading the stock chain on a liter-class superbike or outfitting a torque-heavy adventure tourer, this chain is built to keep pace with your engine's output while delivering smoother, more efficient power transfer to the rear wheel.

This particular configuration features D.I.D's patented X-Ring seal technology, a design that goes beyond conventional O-rings by twisting rather than squashing under load, creating four points of contact instead of two. That twisting action disperses pressure more evenly, cuts internal friction, and locks in lubrication far longer than standard sealed chains — translating to reduced power loss, better wear resistance, and a longer service life between replacements. Layer on D.I.D's Direct Energy Transfer construction, a technology born directly from the brand's MotoGP racing program, and you get a chain engineered for significantly greater resistance to stretch under sustained load.

Features:

• Genuine D.I.D 525ZVM-X2 chain, silver/silver (S&S) finish, 120 links, made in Japan
• Patented X-Ring seal with four contact points for superior sealing performance and minimized power loss
• Direct Energy Transfer construction, developed from D.I.D's MotoGP racing experience, for greater stretch resistance under heavy load
• Manufacturer rated up to 1,300cc, making it one of the strongest 525-pitch chains available for high-horsepower street and adventure bikes
• Average tensile strength of approximately 10,408 lbs for demanding, high-torque applications
• Precision specs: 0.913" pin length, 0.217" pin diameter, 2.4mm inner plate thickness, 2.6mm outer plate thickness
• Includes one rivet-style master link for a secure, permanent connection
• Popular upgrade for bikes such as the ZX-10R, BMW S1000RR, and Ducati V4/1199/1299, as well as adventure platforms like the KTM 1290, Africa Twin, and Tenere 700
• Note: ZVM-X2 connecting links are not interchangeable with older ZVM-X links due to differing pin lengths
• Recommended cleaning every 300 miles using X-Ring-safe cleaners and lubricants to maximize chain life
