Introducing the RM-Z450 with Suzuki fuel injection. Our engineers developed the RM-Z450 using experience gained developing fuel-injection systems for Suzuki's legendary GSX-R road race bikes and the championship-winning QuadRacer R450 ATV.The result is the world's only mass-produced, fuel-injected motocross bike, designed to help you blow away the competition. As if that breakthrough technology weren't enough, our engineers used their experience developing Ricky Carmichael's championship-winning RM-Z450 to redesign the RM-Z450's chassis, suspension and brakes. That means it offers sharper handling, smoother suspension performance and more powerful braking than ever.And just so no one misses the fact that you're on the hottest bike on the track, the RM-Z450 is also completely restyled, with new aerodynamic bodywork that's both sleek and functional. The all-new fuel-injected RM-Z450 - it gives you the power to dominate.
