Three years ago, Suzuki stunned the world with the first fuel-injected motocross racebike. It was more than unique…it was a winner.
In New Zealand and around the globe, the RM-Z450 helped racers collect wins and trophies, fiercely competing in venues from the World MX1 series to America’s AMA Supercross championship.
Now the question: Is there any way to improve on this incredible success?
Sure there is. Take a close look at the 2011 RM-Z450, a thoroughly updated, cutting-edge open-class moto-cross machine that’s more potent than ever. Across-the-board engine upgrades boost power from awesome to awe-inspiring. Detailed frame and suspension modifications improve an already sharp-turning racebike. As a racer, you want quick, laser-accurate steering and confidence-inspiring high-speed handling in one package. And you want a high performance machine whose racing pedigree enables it to be competitive right out of the crate.
When Suzuki introduced the first fuel-injected motocrosser in history, it jumped way ahead of the pack.
With the new 2011 RM-Z450, your competitive advantage just got that much bigger.
