Releae date: 2003-02-27. Color: White + Red.

In 2003, Honda CB1300SF underwent a full model change and became the SC54 type (the engine was also changed and there were no cooling fins). Equipped with a water-cooled, 4-stroke, in-line 4-cylinder 1300cc engine with powerful output characteristics, the CB1300 Super Four, a road sports bike with a powerful form, underwent a full model change and started for sale on February 7, 2003. Compared to the previous model, the dry weight has been reduced by 20kg. By adopting a three-dimensional ignition timing control system and PGM-FI (electronically controlled fuel injection device), it achieves agile and accurate throttle response and smooth output characteristics in all rotation ranges. In addition, the exhaust system has been completely redesigned so that the sound can be felt throughout the body. In terms of functionality, 12 liters of storage space under the seat and theft deterrence mechanism "H・I・S・S" are adopted. Efforts have been made to further improve usability by equipping an information meter that provides the rider with necessary information.

CB1300SF BC-SC54 Overview

This CB1300 Super Four is an evolution model of the CB1000 Super Four released in November 1992 based on the concept of PROJECT BIG-1 ^*1. Even after the displacement was increased to 1300cc in March 1998, this model has been well received by a wide range of people.
This time, the dry weight has been reduced by 20 kg compared to the previous model. By adopting a three-dimensional ignition timing control system and PGM-FI (electronically controlled fuel injection device), it achieves agile and accurate throttle response and smooth output characteristics in all rotation ranges. In addition, the exhaust system has been redesigned to create a rich and comfortable exhaust sound and vibration, and the design allows you to feel the sound with your whole body, creating the joy of driving.
　In terms of functionality, a 12-liter storage space under the seat and the anti-theft mechanism "H・I・S・S" are adopted. Efforts have been made to further improve usability by equipping an information meter that provides the rider with necessary information. While inheriting the powerful form of the CB1000 Super Four, the styling combines functional beauty.
Coloring is a total of 3 colors: a traditional white and red two-tone color, a two-tone color with a gray wing mark image on black, and a simple solid silver color.

• *1 This is a water-cooled DOHC 4-valve in-line 4-cylinder engine, and the concept is to embody the "excitement of driving" by harmonizing powerful engine performance and agile handling at a high level

Main Features of CB1300SF 2003-2008

The weight of the engine alone has been reduced by 8 kg. New engine with improved ease of handling and riding comfort

In place of the rocker arm, the CB1300 Super Four engine uses a "direct push type" where the cam directly pushes the valve via a lifter. As a result, combustion efficiency has been improved, and compactness, weight reduction, and friction reduction have also been achieved. In addition, by making the cylinder block thinner and removing the engine fins, the weight of the engine itself has been reduced by 8kg. It contributes to outstanding maneuverability and improved engine response in various situations. The fuel supply system has been changed from the conventional carburetor specification to a digital control PGM-FI equipped with an advanced 32-bit high-performance ECU. High-speed calculation of data such as engine speed, camshaft speed, water temperature, air pressure, and throttle opening improves throttle response and optimizes combustion efficiency.

Equipped with air injection that contributes to significant reductions in CO, HC, and NOx emissions

Equipped with a built-in air injection system. By sending an appropriate amount of fresh air into the exhaust port of each cylinder, this system reburns the incompletely combusted substances in the port, and in combination with PGM-FI, it reduces CO, HC, and NOx emissions. is realized.

Sound production for even more driving fun

In order to achieve a pleasant exhaust sound, a 4-2-1 type exhaust pipe and a single muffler are used. In addition, a newly developed variable exhaust valve is attached to the cap at the rear of the muffler to achieve a clear exhaust sound with little interference. In addition, a resin washer was used between the rollers of the drive chain to suppress the generation of drive noise, and a rubber mount was used on the upper rear end of the engine to reduce unpleasant noise caused by vibration. It is designed with a focus on "sound".

Compact and lightweight frame that emphasizes comfortable exercise performance

The frame adopts a double cradle frame with a dual backbone to improve overall rigidity balance and reduce the wheelbase by 30mm, achieving a total weight reduction of 7kg in the frame area. It is designed with an emphasis on maneuverability and maneuverability.

Equipped with an information meter that can centrally check the information necessary for driving

Uses a twin-lens meter that displays a specially designed analog type speedometer and tachometer. Inside the tachometer is a liquid crystal panel that displays the clock and fuel gauge, and between the speedometer and tachometer are two total distances, subtraction distances, a stopwatch, water temperature, outside temperature, daily mileage, etc. Equipped with an information liquid crystal panel to display.

Greatly improved loadability, including a 12-liter storage space

In the 12-liter storage space set under the seat, U-shaped locks, rainwear, gloves, caps, maps, etc. can be stored. Load capacity is greatly improved.

Coloring

There are two two-tone color types and one simple solid color type that uses a newly developed ultra-thin color film with very little step on the tank stripe. The two-tone color type is a combination of pearl fadeless white and candy la moana red, which is inspired by the traditional CB series, and a graphic black and force silver metallic color that uses a part of the wing mark as a motif. Force silver metallic is set for the solid color type.
