You feel the wind slicing by you as you speed along the road on the back of your Yamaha, the dirt road bumping beneath you, when you realize you forgot to don your road gear. You riding naked may be the stuff of your nightmares, but Yamaha boldly created the YZ125 naked chassis to put the beauty of the bike and the incredible power of the YZ125 complete engine on display. This motocross bike features a liquid-cooled engine capable of 33 horsepower. Whether you are repairing a bike that has been involved in a collision, replacing an engine that has been damaged or stopped working, or building your dream bike and want to put the heart of a Yamaha into it, a complete engine is the fastest and easiest motor option. Installation and maintenance components such as gaskets and seals are compatible across many model years — for example, if you are installing a 2000 YZ125 engine, you can use 2001 YZ125 engine components. The large inventory on eBay offers a wide variety of options to ensure you find the ideal YZ125 complete engine for your motorcycle project.Shop the extensive inventory of motors, parts, accessories, and complete motorcycle engines for Yamaha!
