All Yamaha YXZ1000R side-by-side race vehicles are based on a production version and then modified to purpose for a variety of off-road racing competition, everything from short-course track series to open desert rally type racing. For example, the Monster Energy / Yamaha / Maxxis / Greaveas Motorsports YXZ1000R above is a purpose-built machine, designed to contend in the world-renowned King of the Hammers rock crawl desert racing event that takes place annually in the Southern California desert of the United States of America. The Yamaha YXZ1000R is built to be the most focused, high-performance side-by-side in the world. Every system on board ensures the YXZ® brings this level of performance to every ride, no matter the terrain, across dunes and deserts, through tight woods and muddy trails. Proven off-road performance makes the Yamaha YXZ the ultimate pure sport side-by-side.
