The powered wheel responsible for propelling a kart forward is a critical component of its design and function. Typically located on the rear axle, this component transfers power from the engine or motor to the ground, enabling movement. A common example is a sprocket-driven wheel connected by a chain to the power source.
Effective power transfer to the ground is essential for achieving desired speed and acceleration. The size, material, and tread pattern of this key component all influence a kart’s performance characteristics, impacting handling, traction, and overall efficiency. Historically, simpler designs utilized direct drive systems, while modern karts often incorporate more complex mechanisms for enhanced control and performance.
