DID VX3 HEAVY DUTY X-RING GOLD CHAIN + JT SPROCKET SET SUITABLE FOR: Honda CBR600RR 2003 2004 2005 2006. DID VX3 X-RING GOLD CHAIN. The VX chain series showcases the industry-leading, patented X-Ring seal technology, which leads to extended chain life, minimal friction, and overall amazing performance. Includes Rivet Type Connecting Link. D’s X-Ring is about 50% lower friction and delivers 50% to 100% longer wear resistance. 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. Packaging design may vary. JT Steel Sprockets are manufactured using only the finest grade of C49 high carbon steel for the rear sprockets, and SCM420 chromoly steel alloy for the front sprockets. Please Note: Rear sprocket colour may vary (Black or Silver). ? WE ONLY SELL QUALITY PARTS SOURCED FROM TRUSTED UK DISTRIBUTORS.
