REV 219 "Twist" Sprocket

The REV 219 Twist Sprocket is a popular choice among 4-stroke kart racers, including those in the Briggs LO206 class and other categories where the sprocket carrier is located inside the bearing cassette. The unique twist design allows for quick gear changes, and the precise wire cut maintains the sprocket's integrity, providing more consistency than a two-piece sprocket or one cut with a hacksaw.

Made from 7075-T6 aircraft-grade aluminum, these sprockets feature a single wire cut that allows the user to "twist" the sprocket over the axle for rapid changes. Each sprocket is individually CNC-machined to an accuracy of 0.01mm, with optimized tooth precision that minimizes friction between the sprocket and chain. This results in reduced drivetrain loss and enhanced kart racing performance.

Our state-of-the-art CNC machines and countless hours of testing ensure the perfect pitch. Under close inspection, you'll notice the chain sits perfectly in the valley of each tooth, reducing friction and distributing the chain load more effectively. This ensures superior performance and reliability in karting, giving you the edge on the track.

Available in sizes 65-78T.
