Starter Case (Bottom) for 50cc ATVs & Dirtbikes

Bottom starter cases protect the lower portion of the starter assembly on 50cc Honda-type ATVs and dirt bikes. They help keep the starter gears aligned and shield the mechanism from dirt, oil, and debris. When a bottom starter case cracks or becomes damaged, riders may notice grinding noises, poor starter engagement, or contamination inside the starter system. Replacing the case restores proper alignment and reliable starting performance on youth models from brands like TaoTao, Coolster, and SSR.
