This, 11 spline, starter fits many of the 150cc to 250cc vertical mount engines from China found on dirt bikes and ATVs. They may also fit some older Honda engines. This has a low mount where as as similar starters come with a higher rear bracket and both styles of brackets come in a 9 spline.
Please ensure yours is the same as this one before you order. There are 4 very similar starters that we carry in stock.
