RM-Z250 Preview

Looking to improve the overall feeling and operation of last year’s RM-Z250 MX motorcycle, Suzuki has made some refinements for 2011.

Just a few motorcycle updates: it meets a stricter AMA Motocross noise limit (94db) while maintaining smooth engine output; the intake and exhaust timing has been changed for better engine feeling with lower noise output; the exhaust pipe length has been changed for better engine feeling with lower noise; ECU settings have been updated for more linear acceleration and improved over-rev; and the radiator hose routing has been changed for more efficient cooling.

Suzuki has always designed their motocross bikes using proven race technology, and the 2011 RM-Z250 is no different.

2011 Motocross 250cc:

  • New graphics complete the 2011 package. In addition, the number plates have a black background to conform to rules for competition numbers.
  • For 2011, the RM-Z250 meets stricter AMA noise limit (94db) while keeping smooth engine output.

Chassis Features:

  • Inverted twin chamber Showa 47mm forks and Showa piggyback shock designed with emphasis on smooth shock absorption and ample bottoming resistance. Tuned to offer superb handling for a wide range of riders, the suspension delivers excellent traction without sacrificing quick-turning ability.
  • The RM-Z250 features a twin-spar aluminum frame and aluminum swingarm developed and refined for a highly optimized balance between rigidity and superb high-speed traction.
  • Smart chassis design details include footpeg brackets shaped to help prevent mud from clogging.
  • Radiator louvers (for the twin side-mounted aluminum-alloy radiators) are joined to the outer bodywork to add strength without adding weight.
  • Race-inspired brake disc rotors offer enhanced cooling performance and efficient mud slinging.
  • High-quality Renthal handlebars featuring a tapered design are fixed to the rubber mounted triple clamp.
  • A gripper seat, with projected cross-shaped patterns on the top surface, provide additional grip.

Engine Features:

  • The RM-Z is powered by a compact and lightweight 249cc, fuel-injected, DOHC, titanium four-valve, semi-dry-sump, four-stroke engine. Its advanced, battery-less fuel-injection (FI) system, features a 44mm throttle body with progressive throttle linkage and a 16-bit computer.
  • The FI system uses a unique capacitor-assisted starting system, and is powered by a durable, lightweight magneto-generator after starting.
  • The engine’s aluminum cylinder is treated with Suzuki Composite Electrochemical Material (SCEM) coating. The cylinder is built for durability, is light weight and the coating allows for efficient heat transfer.
  • A sturdy connecting rod and mirror finishing permits a stunning 13,500-rpm maximum engine speed.

Transmission Feature:

  • A 5-speed transmission provides extra flexibility, offering gear ratios suited for various terrains and conditions.
