Descended from the World Championship winning RM-Z450, the first motocross bike to feature fuel injection, the RMX450Z is designed for serious competition and off-road riders. 

Its powerful and torquey 449cc, liquid-cooled, four-stroke engine shares core technology such as fuel injection with the race proven RM-Z, but with modifications for more usable power across a wider range of conditions.

Its frame, suspension and bodywork are nearly all 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.
