Founded in 1983, we focus on producing cast iron internal combustion engines and cylinders for motorcycles. Over the years we've devoted ourselves to R&D and improving cylinder mechanisms and have obtained several patents for innovations from Taiwan’s Bureau of Standards, Metrology & Inspection, MOEA. Our products are favorites with and well recommended by consumers and buyers from the U.S., Japan, and European countries. To always provide our customers the best, we will continue to introduce patented products to fulfill their needs. Looking forward to your continued patronage.
