Engine modification: the cylinder head is enlarged and the cylinder block is also equipped with fins.
Moreover, the instrument side panel has also been changed, and the exhaust pipe is the same as that of 94.
The crescent bright metallic color on the side of the clutch was cancelled and changed to all black, with Honda in the middle.
1995, the biggest change of CB400-the R version of 95 appeared, and the later CB400SF-S versions were all developed according to the 95R technical standard. First of all, the engine speed of the R version is increased by 1000 rpm, and the red yeast in the tachometer reaches 15000 rpm, while the ordinary version is 14000 rpm.
The carburetor is changed to VP02 with throttle opening sensor. At the same time, the valve spring becomes thicker.
The original stainless steel trumpet exhaust pipe was changed into the sports style of steel front section and aluminum alloy rear section.
The cylinder 1 ~ 2 and the cylinder 3 ~ 4 are connected by air pipes, and the exhaust pipe is changed from 1 to 2 ~ 4.
The frame number and engine number of 1995 CB400 SF are NC3 1- 130 * * and nc23e-160 * * respectively.
The serial number of R version is NC 3 1- 135 * *, and NC 23e- 165 * * 96 has been changed back to the round light, which is a special version that will appear later.
1Feb. 996
CB 400 SF-T 1996 NC 3 1- 140000 1 ~ ~
The back seat is smaller, and the three-dimensional characters are pasted on the fuel tank to distinguish the three-dimensional characters.
The structure of the exhaust pipe has changed, the air inlets of cylinders 2 and 3 of carburetor have been lengthened, and the ignition time has changed again.
The front brake caliper has also been changed to yellow NISSN four pistons. At the same time, the brake disc is very different from Model 95.
This is the last issue of the regular edition. The common version * * * has the same feature, and the exhaust pipe is electroplated horn type.
In March of the same year, the S version was listed:
The engine is an improved version of the R version (the spark plug cap is also red).
The S version of 1996 and the R version of 1995 have not changed much, and the exhaust pipe is changed to aluminum alloy detachable type.
Cancel the three-dimensional characters on the fuel tank, except for the above 96 items, there is basically no difference.
The frame number of 1996 CB400SF is NC 3 1- 140 * * *, and the engine number is nc23e-170 * * * *.
The frame number of r version is NC 3 1- 145 * *, and the engine number is NC 23e-175 * * * *.

On 1999
CB400 SF VTEC1999NC39-100001~ ~
Every part of the new generation CB400 frame has been strengthened, and the engine has been replaced by VTEC.
The pedal part moves backward, the gear connecting rod extends correspondingly, and the lower side plate of the seat changes from triangle to trapezoid in appearance.
The original mechanical fuel tank switch is changed to automatic, and a brand-new electronic induction odometer is adopted. The LCD odometer has an indicator light and a fuel gauge.
The front brake system is a pair of floating drill discs with a diameter of 296mm, and the Japanese Nissin four-piston hydraulic calipers are used instead.
The rear braking system has also been strengthened to a certain extent, and the original double-piston hydraulic caliper has also been changed to a lower design.
The rear rocker arm abandoned the original tension tube connecting rod and adopted a brand-new main section aluminum alloy material.
It is fixed under the right rear pedal with a racing stainless steel ring.

Talk about its super VTEC technology. Changing the engine to VTEC type: the design focuses on the operation of regulating valve. Take a four-cylinder 16 valve engine as an example, that is, each cylinder is equipped with two intake valves and two exhaust valves. When the engine is at a specified low speed, only one pair of diagonal valves can be opened and closed in each cylinder, namely, four intake valves and four exhaust valves, and the other half will start to operate when it reaches a certain set high speed. In this way, the working condition of the engine at low speed has been greatly improved, and the cam curve can be designed to be more suitable for high-speed work. Different from the general cam curve, the speed of each stage must be considered and only a middle value can be taken, thus improving the working condition at high speed. Its biggest advantage is to reduce the wear and tear of the engine itself, improve the air utilization rate and combustion rate, which is beneficial to environmental protection. At the same time, due to the reduction of the amount of exercise, the engine temperature also drops accordingly, which is more conducive to long-term cruising and the daily maintenance cost can be omitted.
When working, the left side is at low speed. You can see that the cam rotates in the air and cannot drive the valve. At high speed, the hydraulic mechanism pushes an object and the valve starts to move. However, there seems to be no rocker arm. It seems that it will be very troublesome to adjust the valve clearance in the future. The volume of the intake passage and the empty filter has increased compared with before. It is worth mentioning that this car is also designed with an intake passage directly leading to the exhaust valve. The purpose is to reduce intake and exhaust pulsation and improve intake efficiency and cooling system. It looks nothing special, but there seems to be an extra water pipe, which must be useful. Compared with the models before 1999, the crankshaft is obviously lighter than 1999. The water jacket is thickened to improve the cooling effect. In order to improve the operability of frequent operation, compared with the models before 1999, a section of ejector rod is added to the clutch.
