RM-Z450 Preview

While designing the 2011 RM-Z450, Suzuki didn’t have to look any further than the 2009 AMA Supercross Championship season. The RM-Z450 dominated the series, and Suzuki fine-tuned that same technology for an even better dirt bike for 2011.

Some of these refinements include meeting a stricter AMA noise limit (94b) while keeping the engine output smooth, increasing the compression ratio from 12.2:1 up to 12.5:1 for higher output, and changed the intake/exhaust timing for a better feeling.

Due to the numerous wins their motocross bikes have, this formula has proven to be successful for Suzuki. And their goal for 2011 was to make their championship-winning machine even more potent right out of the crate.

2011 Motocross 450cc:

  • For 2011, the RM-Z450 meets stricter AMA noise limit (94db) while keeping smooth engine output.
  • Suzuki’s class-leading fuel-injection system uses technology from Suzuki’s championship-winning models-the GSX-R motorcycles and the QuadRacer R450 ATV.
  • The RM-Z450, the first motocross bike to ever use fuel injection, has won both outdoor championships as well as a Supercross championship.

Chassis Features:

  • The RM-Z450’s slim chassis design makes for a comfortable riding position, opening up the cockpit to help allow the rider to actively take control of the machine.
  • Class-leading 47mm Showa inverted forks provide optimum wheel travel and are compression- and rebound-damping adjustable.
  • A Showa piggyback-reservoir rear shock with high/low-speed compression damping adjustment and rebound damping and spring preload adjustments. The rear shock, working through Suzuki’s superlative rising-rate linkage system, provides 310mm of wheel travel, delivering maximum traction.
  • The RM-Z450’s twin-spar aluminum frame and swingarm was developed and refined for a highly optimized balance between rigidity and superb high-speed traction. The lightweight swingarm helps enhance terrain-traversing performance over bumps.
  • Race-inspired disc rotors offer enhanced cooling performance and efficient mud slinging.
  • A stylish two-tone radiator shrouds accentuate the RM-Z450’s agile looks.
  • The RM-Z450 comes with a gripper seat, with projected cross-shaped patterns on the top surface to provide additional grip.

Engine Features:

  • The RM-Z450’s 449cc four-stroke, liquid-cooled, DOHC, four-valve, fuel-injected engine was developed and refined to deliver phenomenal idle-to-redline thrust.
  • The lightweight, battery-less, motocross-use electronic fuel injection system uses progressive throttle linkage for efficient power delivery.
  • A 12-hole fuel injector delivers a fine fuel/air mist for efficient operation.
  • The RM-Z450’s aluminum cylinder is treated with Suzuki Composite Electrochemical Material (SCEM) coating, and was built for durability, light weight and efficient heat transfer.

Transmission Features:

  • A 5-speed transmission provides extra flexibility, offering gear ratios suited for various terrains and conditions.
  • The RM-Z450 has a link-type shifting system, which offers smooth transitions through the gears.
