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 all maintain the RM-Z's slim and aggressive styling, and the motocross seat combines with revised chassis geometry and an 18" rear wheel for a comfortable and confidence-inspiring ride.
An electric start, backed-up with a kick start ensure you can get going quickly and easily wherever you find yourself. The all new headlight and tail lamp add to the RMX's versatility, all powered by a compact battery, located centrally to maintain a balanced bike.
Every feature of the 2011 RMX450Z has been carefully designed with serious off-road riders in mind.
Maximum performance - no compromises.
