Starter Case (Bottom), 100cc ATVs & Dirtbikes

The bottom starter case supports and protects the lower portion of the starter gear system on 100cc ATVs and dirt bikes. When this housing becomes worn or damaged, it can lead to misalignment, grinding, or unreliable starter engagement. This collection includes direct-fit bottom starter cases designed for Honda-type 100cc engines, helping restore proper function and durability to the starting system.
