About YFZ 450 Engine

When you want an All Terrain Vehicle that stands above all the rest, the Yamaha YFZ450 redefines the benchmarks of high-performance in a four-stroke model. Besides the super low dry weight and refined design, the YFZ450 engine is extremely powerful. In fact, this ATV has crushed the competition since its introduction back in 2003. If you look for a YFZ450 engine within the vast inventory on eBay, you may be surprised by how impressive the specs are for this 450-sport class ATV. For example, 2013 models have a 11.4:1 compression ratio and come fitted with a Mikuni 1.653-inch BSR fuel injection system. This makes the engines highly responsive, perfect for a race through the open trails or a competition setting. The 5-speed wet multiplate clutch makes your driving experience even more robust and exhilarating. You may want to customize the configurations on your build, though. You are in luck, as YFZ450 engine rebuild kits are popular on the market. You can also find other needful parts, like YFZ450 engine cases and much more. Do not let yourself be left in the dust. Make the dust yourself with the acclaimed power of the YFZ450.
