Motorcycle chains need to work in a variety of conditions, so original equipment manufacturers choose the chains with the best running characteristics and higher life expectancy. D.I.D has probably worked with every major motorcycle manufacturer and today is one of the major suppliers of original equipment chains.
Thanks to the many years of experience of D.I.D we offer you with the professional line of D.I.D the probably most used motorcycle chains of the world, produced to the highest technological standards.
Do not be fooled by the price, the high quality of the material, the durability and the noticeably better running properties will convince you otherwise.
Also in racing D.I.D draws attention for years, e.g. starring Valentino Rossi, Colin Edwards, Carlos Checa, Hiroshi Aoyama, Alex Barros, Jeremy McGrath, Ricky Carmichael, James Stewart, Chad Reed or Ivan Tedesco, just to name a few.
D.I.D chains are constantly being upgraded and updated to accommodate the ever-increasing demands of modern motorcycles.
Half the Power Loss
(Compared with Normal O-Ring)
D.I.D’s PATENTED X-Ring construction reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and other makers’ modified O-Rings have squashed points that increase friction. The twisting action of the X-Ring disperses the pressure and minimizes power loss.

Times Longer Wear Resistance
(Compared with Normal O-Ring)
The X-Ring’s four contact points greatly increase its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring. X-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain.
