The D.I.D. DKK-012 is a complete chain and sprocket replacement kit designed specifically for the Kawasaki EX250 Ninja 250R from 1988 to 2007. This comprehensive kit provides everything needed to refresh your motorcycle's drive system with premium components engineered for durability and performance.

Kit Includes:

• Chromoly steel front countershaft sprocket (14 tooth)
• High carbon heat-treated steel rear sprocket (45 tooth)
• Rivet-style master link

Advanced X-Ring Technology:

The 520VX3 chain features D.I.D.'s patented X-Ring seal technology, which delivers 32% longer chain life compared to standard O-ring chains. The unique X-Ring design twists between the side plates rather than being compressed, reducing friction by 50% while maintaining superior sealing performance. With four contact points, the X-Rings effectively seal in lubrication while keeping dirt and contaminants out.

Performance Features:

• Tensile strength: 8,210 lbs
• Increased rigidity for reduced flex and improved power transfer
• Smoother handling and quicker throttle response
• Wear life index of 3,500 (standard chain = 100)
• Rated for motorcycles up to 800cc
• Made in Japan

The chromoly steel front sprocket and heat-treated high carbon steel rear sprocket are engineered for maximum durability and extended service life. This complete kit eliminates the guesswork in selecting compatible components and provides OEM-quality gearing in a convenient package.
