Starter Case (Bottom), 125cc 54mm ATVs & Dirtbikes

The bottom starter case supports and protects the lower portion of the starter gear system on 125cc 54mm 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 125cc 54mm engines, helping restore proper function and durability to the starting system.
