Engine, fuel, exhaust, and intake
The RSX850i is powered by an 839-cm3, V-twin, four-cycle motorcycle gasoline engine. It produces 62 hp* and 59.5 lb-ft of torque (80.6 Nm). The advanced electronic controls and fuel-injection systems deliver superb starting, idling, and throttle response during operation.

The engine offers the following performance and reliability features:

  • Delivers exhilarating acceleration for a gravity-defying experience
  • 53-mph (85.3-km/h) top speed
  • Mounted transversely under the seats for a low center of gravity and more equal weight distribution between the front and rear axles
  • Closed-loop electronic fuel injection for superb performance, instant throttle response, consistent performance at high altitude, and hassle-free cold-weather starting (tested to -20?F, or -29?C)
    • Dual oxygen sensors provide a more accurate air-to-fuel ratio balance between cylinders, increasing ability to start and overall engine performance

  • Engine control unit (ECU) cutout to protect critical drive components when the wheel speed far exceeds the vehicle speed
  • Liquid cooled for quieter operation and optimal performance
  • Four-valve-per-cylinder design provides greater efficiency and fuel economy
  • Dry sump oiling system
    • More efficiently lubricates the engine resulting in more available horsepower over a conventional wet sump design
    • Oil tank is more easily accessible for checking and filling the oil
    • Allows for the engine to be mounted low in the vehicle to lower the center of gravity

  • Full-pressure lubrication system
  • Spin-on oil filter with drain bracket and oil drain valve enable easy servicing
  • High-flow air filter
    • Utilizes nano fiber technology to increase the efficiency of the filtration without
      sacrificing horsepower

  • See-through coolant recovery tank permits the operator to check the coolant level without having to remove the radiator cap
    • Sealed radiator compartment keeps trash and debris on the outside of the grille

  • 450-Watt maximum magneto charging system
  • Auto-start electronic ignition system optimizes ECU inputs for easy starting
  • Electronic ignition is continuously variable for optimum engine power and provides fast, reliable starts
  • Exhaust system design
    • Large-diameter header pipes optimized for maximum horsepower output collect
      in high-volume muffler
    • Full Stainless steel for longevity under severe loading and heat
    • Additional heat wrap ensures heat dissipation through the tail pipe
    • Spark-arresting muffler is USFS approved

  • Large 7.4-gal. (28-L) fuel tank
