Transmission Gears (Automatic with Reverse), 70cc ATVs & Dirtbikes

Automatic-with-reverse transmission gears help 70cc Honda-type ATVs and dirt bikes shift smoothly and move confidently in both forward and reverse. These gears manage internal power transfer and directional changes, making them essential for young riders learning to control their machines. Worn or damaged gears may cause slipping, grinding, or trouble engaging reverse. Replacing them restores smooth, reliable operation on models from brands like TaoTao, Coolster, and SSR.
