Yamaha XT660 Z Tenere Covers 2008 to 2015 Models Genuine DID Gold X-Ring Chain & JT Sprockets Kit Front & Rear Top Quality JT Carbon Steel Sprockets (520 Pitch Chain,15 Tooth Front 45 Tooth Rear) 1 x DID Japanese Professional Gold X-Ring VXGB Series OE Chain (with a rivit type connecting link) Please note;The image is an example only DID is a Japanese original equipment chain D.I.D X-Ring reduces friction by twisting between the side plates insteadD.I.D’s X-Ring is about 50% lower friction and delivers 50% to 100% longer wear resistance.D.I.D’s X-Ring twists under pressure from the side plates reducing friction compared to other type squashed designs.Special low-friction "X" type O-ring is used to increase performance and provide better sealing to keep dirt out and lubrication in. Superior strength to combat breakage. Normal O-Rings and other makers’ modified O-Rings have squashed points that increase friction. The twisting resilience of the X-Ring’s four sections greatly increases 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 chainJT SprocketsJT sprockets are made using only the best available materials.SCM415 chromoly steel alloy for front sprockets, and we are the only sprocket manufacturer using the ultra-durable high carbon C49 steel for rear sprockets.The JT Sprockets factory is the largest and most advanced in the world. It is fully equipped with high accuracy machinery, including the latest generation of CNC computer design and computer controlled metal cutting equipment.The essence of a high quality sprocket is in the high precision of manufacturing and the inherent quality of the material. Through accurate machining, JT ensures maximum durability and performance.JT Sprockets are manufactured the right way – by hobbing, machining and drilling. This is the only proven way to achieve the closest of tolerances and the most accurate teeth profiles.Heat treated and hand finished to perfection, all JT sprockets meet or exceed the highest possible quality standards set for the motorcycle industry.
