Main Features of HONDA CB400SF VTEC Spec II 2002
The CB400SF Hyper VTEC Spec II changed the operation of the VTEC system to trigger at 6,300 rpm along with updated ignition timing map. Lighter, smaller oil filter and front brake calipers were lifted from the super-sport CBR900RR. Air intake noise was reduced by enhancing the surface rigidity of the air cleaner case. Chipping guards were added to the front fork tubes. Weight increased by 1 kg (2.2 lb). An LCD odometer/trip-meter and clock + fuel gauge were integrated in the speedometer and tachometer faces respectively, as well as adding the HISS ignition security system.
Equipped with a Hyper VTEC Spec 2 engine with improved power characteristics in the mid-speed range
The engine is liquid-cooled, 4-stroke, DOHC, in-line, 4-cylinder, 399cm3. The engine adopts Hyper VTEC Spec II, an evolution of Honda's original Hyper VTEC. The valve timing, exhaust system Specifications, carburetor settings, and ignition timing have been changed to improve power characteristics, eSpecially in the mid-speed range. In addition, the switching timing from 2 valves to 4 valves has been changed from the conventional 6,750 rpm to 6,300 rpm. Even beginners can easily experience the powerful 4-valve range.
Use of an intake and exhaust system that allows you to experience the change in sound pressure when switching from 2 valves to 4 valves
For the intake and exhaust system, in order to achieve a crisp intake and exhaust sound, the surface rigidity of the air cleaner case has been improved and the exhaust system has been revised to reduce the sound pressure at the rider's ears. In addition, the sound pressure in the high frequency range that can be heard as noise is suppressed, and the sound pressure in the low frequency range of the intake and exhaust sound is increased. It is easy to experience the sound pressure change and comfortable exhaust sound when switching from 2 valves to 4 valves.
Honda's unique anti-theft mechanism H/I/S/S is used for the first time in the 400cc class
For the first time in the 400cc class, Honda's unique anti-theft mechanism "H・I・S・S", which is used in large motorcycles such as the CBR1100XX and CBR600F4i, is used as the anti-theft mechanism. "H・I・S・S" makes it impossible to start the engine with anything other than the genuine key, and by pressing a button the 24-hour indicator lamp flashes, improving theft deterrence effect. In addition, it is compatible with the vehicle location search service system "Coco-Secom" developed in cooperation with Secom Co., Ltd., and has a space for installing units and in-vehicle chargers, making it a "Coco-Secom Honda recommended model".
Renewed twin-lens electric speed and tachometer for improved visibility and functionality
A simple two-lens type electric speedometer and tachometer are used for the configuration around the meter. The design has been renewed considering visibility and functionality. A multi-function liquid crystal display with excellent visibility is adopted in each meter panel. The left speedometer has a twin trip meter and odometer, and the right tachometer has a clock and fuel gauge (with a remaining amount warning function).
Adopted color order plan with 18 patterns for wider selection
The standard coloring is Pearl Prism Black and Pearl Fadeless White for the solid type, and Candy Tahitian Blue and Force Silver Metallic for the striped type.
