Our Story

Who We Are

Rooted in precision component manufacturing with aerospace-grade standards, Chengdu E-manufacture Co., Ltd. is built on a foundation of precision engineering, strict manufacturing discipline and rigorous quality control. ULTSPEED serves as our proprietary brand. Founded in 2001, we extended our manufacturing expertise to the professional motorcycle aftermarket, bringing the same dedication to precision and quality to our motorcycle components and custom solutions. We have cultivated deep expertise across three core business segments: Harley-Davidson, off-road motorcycles, and electric motorcycles.

For more than two decades, Ultspeed has focused on the North American and European premium motorcycle aftermarket, building deep expertise in the standards and expectations of these markets. Beyond merely supplying parts, we are an integrated solutions partner, delivering tailored engineering, manufacturing, and lifecycle support—proven through long-standing partnerships with professional distributors across both markets.

As our business and market expertise grew, our capabilities expanded across broader motorcycle applications and six major product categories: brake systems, suspension and frame components, exterior customization parts, engine components, transmission accessories, and complete customization kits.
