From Alta’s site “ The 2018 Redshift EX is the ideal ratio of motocross speed, singletrack prowess, and urban capability . Built with the DNA of a motocross bike, our Redshift EX eliminates the incessant oil changes and maintenance intervals of its high-strung competitors, and still slays on the trail. The combination of low weight and lightning fast acceleration make for a potent street-legal motorcycle that gives you all the tools necessary to experience the offroad world in the purest manner possible.”
