Specifications - ST1300

With the new ST1300 and ST1300 ABS, Honda reinvents the world's best sport-touring motorcycle, providing strong, reliable performance, superb handling and luxurious comfort for motorcyclists exploring the twists and turns of long-distance travel.

Features & Benefits:

   * Powerful, new liquid-cooled 1261cc longitudinally-mounted V-4 engine produces 116 bhp at 8000 rpm and 85 lb./ft. of torque at
      6500 rpm  for effortless acceleration and passing power.

   * The ST1300 is 33 pounds lighter than the ST1100. Together with a 2.2-inch-shorter wheelbase of 59 inches, the new ST1300
      provides exceptional sporting feel.

   * The 2003 ST1300 meets the California Air Resources Board (CARB) 2008 emissions standards.

   * Engine length is shortened by 2 inches compared to the ST1100, permitting optimum rider and passenger ergonomics. Placing the
      rider 1.6 inches closer to the steering axis also improves steering feel and helps deliver even better handling.

   * Honda's latest programmed fuel injection (PGM-FI) and electronic digital ignition maximize power output and provide immediate
      throttle response.

   * All-new aluminum frame combines optimal rigidity and tuned flex to produce excellent handling, superb riding comfort and
      wonderful road feel.

   * A second model is equipped with an Antilock Brake System (ABS) for even better braking control.

   * Touring features include new full-coverage bodywork, three-way adjustable rider's seat, and two large, 35-liter detachable
      saddlebags. A push-button, motor-driven adjustable windscreen is standard equipment on the ABS model.


Engine/Drivetrain:



   * Compact, powerful 1261cc DOHC 90° V-4 engine with an oversquare bore and stroke of 78mm x 66mm. Longitudinal
      engine-mounting eliminates an inefficient 90-degree turn in the power flow for improved drivetrain efficiency.

   * The crankshaft is lowered 20mm in the crankcase, lowering the ST1300's overall center of gravity for improved handling.
      The 360 degree crank contributes to a very broad powerband. Two engine counterbalancers virtually eliminate primary and
      secondary vibration. Both gear-driven counterbalancer shafts are installed in the lower crankcase, to the left side of the
      crankshaft. The first shaft is driven directly by the crankshaft at a 2:1 ratio. The second shaft is positioned below the first and
      is driven in the opposite direction by the first balancer shaft's drive gear. The combination of these two balancers assures a
      supremely comfortable ride for the long-distance touring rider.

   * Aluminum composite cylinder sleeves are high-pressure-formed from sintered aluminum powder impregnated with ceramic
      and graphite. The composite sleeves provide better wear resistance and superior heat dissipation compared to
      conventional sleeves.

   * New silent-type cam-chain drive eliminates the previous model's wider belt-driven cam drive, reducing engine length 10mm
      and lowering overall weight.

   * Large, 31mm intake valves and 27mm exhaust valves feed a redesigned combustion chamber with a 10.8:1 compression ratio.

   * Direct shim-under-bucket valve actuation system ensures high-rpm durability and allows 16,000-mile valve maintenance intervals.

   * High-pressure PGM-FI delivers fuel at 50 psi to the four injectors mounted in each 36mm throttle body. Fuel is delivered
      through 12 laser-drilled nozzle holes in each injector, producing a very fine spray and a highly combustible air/fuel charge
      for maximum combustion efficiency and power.

   * PGM-FI combines a sophisticated throttle sensor, advanced 3-D digital fuel injection and ignition mapping and precisely
      metered fuel delivery to produce smooth and linear throttle response.

   * ECU-controlled closed-loop emission control system utilizes two oxygen sensors to constantly deliver a precise air/fuel mixture,
      while two exhaust catalyzers further reduce emissions of carbon monoxide, hydrocarbons and oxides of nitrogen.

   * Auto-enriching system is integrated into PGM-FI module, optimizing the air/fuel mixture on cold starts and eliminating the need
      for a manual choke.

   * Four-into-two stainless steel exhaust system features a pair of attractive triangular-section, 5.4-liter mufflers with stainless steel
      heat shields.

   * Dampers on the transmission mainshaft, clutch and drive shaft reduce noise, vibration and driveline lash.

   * High-output, 480-watt air-cooled alternator is relocated between the cylinder banks, contributing to a shorter and more
      compact engine design.

   * Redesigned U-shape aluminum radiator has 7 percent greater cooling capacity, and a new ring-type fan draws air through the
      radiator at low speeds to ensure stable operating temperatures for consistent performance and long engine life.

   * Sturdy eight-plate hydraulic clutch.

   * All-new cassette-type five-speed transmission shortens overall engine length by 40mm and has approximately 5 percent
      lower gear ratios than the ST1100 for quicker acceleration and excellent roll-on performance.

   * Quiet and reliable shaft-drive system is virtually maintenance-free.


Chassis/Suspension:

ST1300 Frame



   *  All-new aluminum frame is 16.5 pounds lighter than the steel frame it replaces and features a massive steering head
       casting and triple-box-section spars. The V-4 engine serves as a tuned, stressed frame member. The solid
       engine-mounting system utilizes specially designed hangers and carefully matched mounting bolts to provide both
       excellent road feel and minimal engine vibration.

   * New lightweight aluminum swingarm is 1.9 pounds lighter than the steel unit it replaces and is carefully matched to
      the frame to provide an ideal balance of rigidity and tuned flex for optimal handling.

   * Rigid aluminum upper triple-clamp and a 45mm Honda Multi-Action System(tm) (HMAS(tm)) cartridge front fork provide
      excellent suspension control in a wide range of riding conditions.

   * The rear suspension incorporates a single shock, which mounts directly on the swingarm. The shock offers 1.2 inches of
      spring preload adjustability.



  *  Linked Braking System(tm) (LBS(tm)) uses a second master cylinder and a proportional control valve (PCV) to couple the
      three-piston calipers of the dual-disc front and single-disc rear brakes for even better braking feel, while providing the
      peace of mind of an LBS system. Using the front brake lever activates the outer two pistons of the front calipers and
      the center piston of the rear caliper. Rear pedal engagement activates the two outer pistons of the rear brake caliper
      and the center pistons of the front calipers, and a delay valve slows initial front brake response to minimize front-end dive.

  *  ABS model combines with LBS for a wide range of braking and steering control. ABS features an electric-motor-driven
      modulator that gives quick, precise braking pressure adjustments and smooth ABS operation. The system incorporates
      an integrated ECU controller, self-diagnostics with an interactive ECU test function, and automatic protection against system failure.

  *  The ST1300's 310mm stainless steel floating front brake discs feature a lightweight seven-spoke inner rotor, saving a
      total of 4.7 pounds of unsprung weight over the previous model. The 316mm rear rotor saves another 10.5 ounces,
      further reducing unsprung weight.

  *  Three-spoke U-section cast aluminum 3.5-inch-wide rear wheel is nearly 9 ounces lighter than the previous design and
      sports a large, low-profile 170/60ZR-17 radial tire. The three-spoke 3.5-inch-wide front wheel is 2.6 pounds lighter and
      carries a 120/70ZR-18 radial tire.


Additional Features:

   * Full-coverage bodywork features an Aero-Ellipse form that incorporates striking parabolic lines to accentuate the
      look of speed as well as enhance stability at high speeds.

   * New three-position rider's seat provides an adjustment range of 1.2 inches vertically and 1.0 inch horizontally. From
      the forward and lowest position, the seat can be moved up 0.6 inches and back approximately 0.5 inches to the
      middle position and again by the same amount to the highest rear position.

   * A motor-driven adjustable windscreen on the ST1300 ABS offers 7.4 inches and 13 degrees of adjustability for greater
      wind protection and touring comfort. A thumb-operated pushbutton on the left handgrip operates the windscreen motor.
      An additional 2.3 inches of manual adjustment is possible by repositioning the windshield on the mounting brackets.
      (Standard version does not have motor-driven windscreen.)

   * Newly designed lockable and detachable saddlebags hold 35 liters each (large enough for a full-face helmet). The
     saddlebags contain straps to limit bag opening to 90 degrees to better secure the contents. The straps are easily
     unbuckled when the bags are dismounted, permitting full access.

   * Rugged, plastic-covered body-protector stays extend outward to protect the bodywork in case of a tipover.




   * Dual-section fuel tank places 5.5 gallons of fuel in the conventional tank location with an additional 2.2 gallons
      located in a sub-tank located low in the chassis. This results in an increase in fuel capacity and an even weight
      distribution for fuel.

   * An electric fuel pump operates inside the sub-tank, providing consistent fuel pressure for the PGM-FI system.

   * Headlight features dual lenses with twin-filament H4 low/high beam bulbs and multi-reflectors.

   * A convenient push button located on the left side of the fairing electrically adjusts the headlight height over
      a 2.5 degree range.

   * Roomy cockpit and ergonomically designed dual-density seat offer true long-haul comfort.

   * Attractive, lightweight two-piece aluminum handlebars.

   * A locking left-side fairing pocket offers the carrying capacity of an automobile console; a weather-resistant vinyl
      flap covers the right-side pocket.

   * Breakaway rear view mirrors minimize damage in the event of a tipover.

   * Padded passenger grabrails.

   * Convenient centerstand assist-lever folds neatly away when not in use.

   * Integrated front and rear turn signals.

   * Integrated ignition switch/fork lock. A single ignition key operates all locks.

   * Handlebar switches and controls use internationally approved ISO graphic symbols.

   * Transferable three-year, unlimited-mileage limited warranty.
