Renthal 50-Tooth Green Rear Sprocket for Kawasaki KX65 408U-420-50GEGN

If you're running a Kawasaki KX65 in competitive or recreational off-road conditions, sprocket wear directly impacts your power delivery and acceleration. The Renthal 50-Tooth Green Sprocket replaces worn or damaged stock units with a precision-engineered component that combines lightweight durability with proven self-cleaning mud grooves—keeping your drivetrain responsive when conditions get gnarly.

Built to handle the demands of modern pit bike and mini moto racing, this sprocket delivers consistent power transfer across the entire RPM range without the maintenance headaches of debris-clogged teeth.
