Stripped to its essence, motocross requires a racebike to do three key things: Run, Turn and Stop – all better than the rest. Now in its 15th model year, the RMZ450 is fully redesigned with a laser focus on achieving this winning balance. Fortunately, the RM-Z450 already has a heritage of 26world and national championships to build on, including five AMA 450 Motocross and two AMA 450 Supercross titles. To this winning history now comes fully re-engineered engine, chassis and electronics, plus dramatic new styling.
