This critical component transfers power from the engine to the axle, enabling the vehicle to move. Similar to a chain on a bicycle, this looped band connects two rotating shafts, translating engine rotation into wheel movement. A typical example is a rubber belt reinforced with fibers for durability and grip.
Efficient power transmission is essential for optimal performance. Choosing the correct type and maintaining its condition ensures responsive acceleration, top speed, and a smooth ride. The development of durable, high-performance materials has significantly contributed to the advancement of karting technology, allowing for faster speeds and improved handling. Historically, simpler materials were used, but modern advancements have resulted in stronger and more efficient power transfer mechanisms.
