2006 Suzuki RM-Z450





The Ultimate Four-Stroke Weapon

The RM-Z450 offers supremely balanced performance - strong, controllable power delivery complemented by extraordinarily lightweight handling. In fact, the RM-Z450 is extremely lightweight - and it has incredible performance to match. That combination means you can launch out of corners with breathtaking acceleration and attack the nastiest sections of the track with total confidence. The Suzuki RM-Z450 is loaded with advanced technology to make it remarkably easy to ride. Including the Suzuki Advanced Sump System, the Suzuki Active Vent System, lightweight and durable titanium valves, hollow billet camshafts and much more.

The RM-Z450. It's the bike you get when you combine Suzuki's championship-winning motocross program with the legendary GSX-RTM four-stroke road-racing program.
