Extron #219 89-tooth kart sprocket for racing go karts. Typically this sprocket is utilized with Kid Kart go karts, and features a plastic-reinforced nylon construction for reduced rotating weight and light-weight performance.
Manufactured by the team at Righetti Ridolfi, the Extron sprocket is a lightweight solution to your powertrain, providing reliable performance while keeping rotating weight at a minimum. This keeps your rolling speed up in the corners when off throttle, and improves braking and acceleration performance throughout your lap.
Because of its lightweight design, the Extron sprocket is particularly popular with the Honda GXH50 or Comer 50cc engines used in the Kid Kart categories.
Each sprocket is sold individually, with no additional mounting hardware. The sprocket is #219 in chain pitch, and 89 tooth count.
