Tokyo, January 30, 2003 --- Honda
Motor Co., Ltd. has announced a full model change for its
CB1300 SUPER FOUR large-displacement road sports bike. The new bike, which features
dynamic styling combined with a powerful water-cooled, 4-stroke, in-line 4-cylinder 1300cc
engine, goes on sale February 7th.
The new CB1300 SUPER FOUR is the latest advancement on the CB1000 SUPER
FOUR model, based on the "Project Big-1"*1 concept,
that was first introduced in November 1992. The displacement was boosted
to 1300cc in March 1998, winning over a broad spectrum of motorcycle enthusiasts.
| *1 |
The "Project
Big-1" concept seeks to achieve exciting driving performance through a sophisticated
blend of light, nimble handling and powerful engine performance in a bike
equipped with a water-cooled, DOHC 4-valve, in-line 4-cylinder engine. |

CB1300 SUPER FOUR
|
The dry weight of the new bike is 20kg lighter than previous models, and a 3-D ignition
timing control system and PGM-FI (Programmed Fuel Injection) have been added to achieve
precise, sensitive throttle response and smooth powerful output characteristics. The exhaust
system and other components were also redesigned to create a dignified, comfortable exhaust
sound and resonance that the rider experiences through his or her entire body, further
enhancing the bike's driving pleasure.
Functional improvements include a 12-liter storage compartment under the seat and Honda's
original HISS (Honda Ignition Security System) anti-theft device. An information display has
also been added to provide the rider with all required information, further heightening the
bike's ease of operation. The new model inherits the CB1000 SUPER FOUR's dynamic
styling, combining beauty with functionality.
In addition to the traditional two-tone color combinations of white on red and black on gray
embellished with a wing-mark motif, a solid-color type is also available in simple monotone
silver, for three color schemes in all.

 |
A new more compliant, more fun-to-drive engine that is 8kg lighter
The new CB1300 SUPER FOUR engine's rocker arms have been replaced with a "direct
push" system in which the cam lobes operate via lifters to open and close the valves
directly. This results in greater combustion efficiency and a more compact, lightweight,
low-friction design. Further weight reductions attained through the use of a thinner cylinder
block and the elimination of engine fins result in an engine unit that is 8kg lighter.
Innovations throughout ensure unrivalled operability and engine response. In the fuel
system, the carburetor has been abandoned in favor of digitally controlled PGM-FI
equipped with an advanced 32-bit high-performance ECU that executes high-speed
analysis of engine rpm, camshaft rpm, water temperature, atmospheric pressure, throttle
opening, and other data to achieve improved throttle response and optimum combustion
efficiency.

|
Air injection contributes to a major reduction in CO, HC, and NOX emissions
A built-in air injection system delivers the optimum amount of fresh air to the exhaust ports
in each cylinder, causing incompletely combusted materials in the port to re-ignite. In
combination with the PGM-FI, this results in a major reduction of CO, HC, and NOX
emissions in the exhaust.
|
|
Exhaust sound performance that further enhances the fun of the ride
In order to produce a crisp, pleasant exhaust sound, the 4-2-1 exhaust pipe is fitted with a
single-pipe collector and muffler. The muffler's rear cap is also equipped with a newly
developed variable exhaust valve to create a clear sound with a minimum of interference
noise. Other improvements include a drive chain fitted with plastic washers between the
rollers to suppress drive noise and a rubber rear upper engine mount that reduces
unpleasant vibration noises, resulting in a pleasing sound that further enhances the fun of
the ride.
|
|
A lighter, more compact frame delivers comfortable driving performance
The dual-backbone, double-cradle frame provides improved overall rigidity and balance. A
shortening of the wheelbase by 30mm, in addition to other modifications, has resulted in a
7kg weight savings in the frame area. The new design emphasizes handling and driving
performance.
|
|
Meter display provides instant confirmation of all important driving information
The custom-designed, twin-gauge display features an analog speedometer and tachometer.
Inside the tachometer is an LCD panel displaying a clock and fuel gauge, and between the
speedometer and tachometer is an LCD information display that shows two odometers,
distance remaining, a stopwatch, coolant temperature, ambient air temperature, distance
traveled per day and more.
|
|
Major increase in cargo capacity, including a 12-liter storage space
The 12-liter storage space located under the seat is big enough to accommodate a U-lock,
rainwear, gloves, cap, maps, and more. This cargo space, combined with the six hooks
located at the back of the seat, gives the new CB1300 SUPER FOUR a major increase in
cargo capacity over previous models.
|
|
Coloring
The new CB1300 SUPER FOUR is available in either a two-tone color scheme employing
newly developed ultra-thin color film for the tank stripes for a nearly flush fit, or a simple,
solid color scheme. The two-tone type is available in either Pearl Fadeless White and
Candy Aramona Red, traditional to the CB series, or Black and Force Silver Metallic with a
graphic design patterned after a partial wing mark. The solid color type is Force Silver
Metallic.
