Precision CNC Machined to extremely tight tolerances. Case hardened and core refined 655M13 Nickel- Chrome-Molybdenum alloy steel to give the ultimate combination of strength and hardness. Computer aided 'Ultra light' design minimizes weight while maximizing strength.
"The best sprocket to date. Far superior in every way. compared: Vortex, Sunstar, JT. It would be nice if they made a 19 or 20 tooth for the top speed guys. Close tolerances. Lite weight but, still strong. Wheeling a Gen 2 Hayabusa strong."
Vortex Sprocket: With the Vortex sprocket and chain kit you can expect race quality and killer street looks. The Vortex black aluminum rear sprocket will not only make your motorcycle look faster, it will increase your motorcycles acceleration by reducing the rotating mass. In addition to quicker acceleration, reduced rotating mass also translates into quicker braking and better handling. Vortex makes their front sprockets out of high quality stainless steel that has been drilled to save weight. The Vortex rear sprocket has been anodized black for a durable finish and non-stock look. Constructed of the highest quality 7075 T6 aluminum maximizes durability and weight savings. Vortex uses a CNC machining process to ensure the tightest tolerances and reduced chain drag. Match these Vortex sprockets up with a RK or DID chain for the ultimate combo on your motorcycle. RK Chain: All RK Sealed O-ring type chains feature heat treated hi-carbon alloy steel components with seamless rollers and shouldered bushings, and are fitted with a variety of O-ring seal designs. All RK O-ring seals are made from an advanced Nitrile Butadiene composite for maximum performance and wearlife. D.I.D Chain: D.I.Ds 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. The X-Rings 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.
"I have already written about DID chain. This is on the "Vortex Sprockets". Sprockets are very well made. I have used Sunstar and JT. Vortex is the best quality. No manufacturing flaws that I can see. Unlike the two other companies I've used. Awesome looking. Black coating on rear sprocket seems to be holding up, so far. 1,200 miles and still looks like new. To soon to comment on longevity. The price to quality is great."
D.I.D is the number one motorcycle chain in the world. D.I.D chains are used by factory races teams from all manufacturers in race series everywhere. D.I.D has merged the Professional O-Ring V Series and the top selling Premium X-Ring VM Series into "ONE" New Pro-Street X-Ring VX Series. Created from the severe demands of todays top World Superbikes, D.I.D is proud to introduce the new high performance VX Series. In developing this new series, D.I.D focused on improving "Rigidity." Traditionally, "Tensile Strength" has been used to indicate the overall strength of a chain. But Tensile Strength is only a laboratory static measurement of a chains "breaking point." Rigidity, on the other hand, is the ability of a chain to withstand forces that occur in a riders real world experience. Increased rigidity means better power transfer from the engine to the ground and greater resistance to stretching under load. This translates into smooth handling and quicker response time. The greater rigidity of the VX series brings smoother handling, quicker response and reduces power loss. All components shot-peened and heat treated. Special low-friction "X" type O-ring is used to increase performance and provide better sealing to keep dirt out and lubrication in. Reinforced rollers for greatest impact resistance. Longest possible wear with solid bushings; projected wear life 36 times longer than a standard chain under similar conditions. Average tensile strength of 9,220 pounds. Wear life index: 3800. Maximum recommended engine displacement: 1000cc. Weight (per 100 links): 4.27 pounds. Includes one patented "TFC" master connecting link; clip style master links are sold separately. 120 links. To maximize performance, D.I.Ds race proven X-Ring design delivers overall improved performance that meets the demands of todays high-performance machines. The VX Series is the ultimate in performance and durability, and is now available at a new low O-ring chain price. D.I.Ds New Pro-Street X-Ring VX Series Chains are a perfect match for your dual sport, sport bike or sport touring bike. Half the Power Loss - Compared with Normal O-ring chains, D.I.Ds 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. 1.5 to 2 Times Longer Wear Resistance - Compared with Normal O-ring chains, the X-Rings 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.
"I bought this chain in a chain & sprockets package. First DID chain for me. I've put 1,200 miles on it. Have made three chain adjustments due to stretching. I think its slowing down. Unable to comment on x-ring better then o-ring at this time. Quality of side plates, rivits and rollers. All look to be of high quality. Factory DID grease very hard to remove from plastics or anything it gets on. So, remove as much excess as possible before riding. Great price to quaity."
"I only wanted to find out what gearing would work best for my use. I didn't want to spend anymore money then I had to. So, Excellent Sprocket for the money. Chrome Sprockets are just for show, or short use. The chrome on the teeth, gets crushed in to shinny powder and scratchs your wheel if not cleaned cerefully. Means to an end."
