Transmission Gears (Automatic), 70cc ATVs & Dirtbikes

Automatic transmission gears for 70cc Honda-type ATVs and dirt bikes help deliver smooth, consistent power for young riders. These internal gears manage forward drive and overall engine-to-drivetrain power transfer. When the gears become worn or damaged, you may notice slipping, hesitation, or unusual noises during acceleration. Replacing them restores dependable performance on models from brands like TaoTao, Coolster, and SSR.
