RK Excel GB415HRU-120 Gold 415 x 120 Racing Drive Chain

415 Sprint Racing Chain Series Features RK’s proprietary Ultra Thin U Seal Rings. U-Rings have a seal thickness less than 50% of the common O-ring seal, making it possible to design a Sealed Chain with the weight of a Non-Sealed Chain. Running a Sealed Chain on race machines can minimize the elongation of the chain, keeping high horsepower transmission efficiency throughout the duration of the race. HRU Racing Chain Series are designed strictly for

The RK Excel GB415HRU-120 415 Sprint Racing Chain is designed for race machines requiring strong, efficient power transmission with reduced chain weight. This gold-finished drive chain uses RK’s proprietary Ultra Thin U Seal Rings, which are less than half the thickness of conventional O-ring seals. The result is a sealed chain engineered to deliver the low weight and responsive performance typically associated with a non-sealed chain.

Built for competition use, the RK Excel 415 HRU Racing Chain helps minimize chain elongation during demanding race conditions, supporting consistent transmission efficiency throughout the event. With a tensile strength of 4,800 pounds, it is rated for race applications up to 250cc and engines producing up to 60 horsepower. The chain is supplied in a 120-link configuration and is intended for professional installation with compatible 415 sprockets and drivetrain components.
