Descended from the Championship winning RM-Z450, the first motocross bike to offer high-performance Suzuki fuel injection, the RMX450Z is a serious off-road bike for serious trail riders. Its powerful and torquey 449 cubic centimeter, liquid-cooled, four-stroke engine shares all core technology with Suzuki’s winning open-class motocrosser. Its frame, suspension and bodywork are all nearly identical to the RM-Z450’s—maintaining that model’s slim, aggressive styling. Only changes to make the RMX450Z a superior trail machine have been made—maximum performance – no compromises. That’s like taking your hard-core motocross machine out onto the trail. Only better. Much better.
