The 20th anniversary event of the opening of the Honda Collection Hall was held on the south course of Twin Ring Motegi on July 16 and September 24, 2018. The usual dynamic confirmation tests were racers and others in many cases, but this time around 20th anniversary commemorative commodity special running was carried out, the epoch-making model from the dawn of Honda to the present showed off running.
Caffe racer style innovative design excelled
This machine was released at the revision of the licensing system and became the origin of "400" as a matter of fact. Following CB 750 FOUR, which became synonymous with Nanahan, CB 500 FOUR, CB 500 FOUR and Honda had three different four-cylinder CB lineups by 1972. However, regarding 350, it was compact and easy to handle, but on the other hand, there was pointed out that lack of acceleration feeling was lacking, and power was lacking, and we decided to reexamine the figure that should be the youngest child of the inline forerunner from the starting point. What was imaged there was "movement" like an athletic player, that is, an agile character, 750 "rigid", 500 "static" to be clearly distinguished.
It became popular from the engine expanded to 408cc and the fresh style of 4into1 gathering, but about a year after debut, a medium size limited license from October 1975 to 400cc was introduced, it did not become a big hit. In the latter model, variations of 398 cc of Fore-I and Fore-II were also prepared, but production ended in May 1977. However, immediately after that, the price rose sharply in the second hand market. It has a strong impact which remains in the mind of the user up to now.
[HONDA DREAM CB 400 FOUR December 1974]Returned to the origin of CB super sports, adopted the cafe racer style which showed signs of trends in Europe and the United States and the collective evacuation system which led the four exhaust pipes to one muffler as quickly as possible I gained high popularity. • Air-cooled 4-stroke 4-cylinder OHC 408cc 37ps / 8500rpm 183kg 4 Carburetor 6-speed shift
[HONDA DREAMCB 350 FOUR 1972] It was released as a long distance touring bike with luxurious functions and appearance as a class best car in the 4 cylinder series following CB 750 FOUR (1969) and CB 500 FOUR (1971). • Air-cooled 4-stroke 4-cylinder OHC 347cc 34ps / 9500rpm 170kg 4 Carburetor 5-speed shift
The collective muffler also has merit in terms of performance
The 4-cylinder engine combines the exhaust gas from the four cylinders into a large capacity collecting chamber and promotes the exhaust of other cylinders according to the explosion order of the multi-engine, thereby not only exhibiting greater power but also mutual exhaust interference Also demonstrate the silencing effect. Based on CB 350 FOUR which realized both weight saving and durability, the engine aims to make the weight the same as 2 cylinder 350 kg. As a countermeasure against heat due to an increase in displacement, one fin of a cylinder and a cylinder head is added, and the outer periphery of the fin is enlarged.
Improvement of output characteristics and reduction of exhaust sound by the collective muffler of the first mass-production car, combined with improvement of driving force etc. at each gear by adopting six-step mission, demonstrate excellent acceleration performance. The muffler is composed of the chamber (primary expansion chamber) of the collecting part and the muffler (secondary expansion chamber), and the silencer part also contributes to productivity improvement by adopting the new production method of the iron sheet rolled taper pipe .
From the catalog of those days. As a point of 4into 1, "Honda's high efficiency collective evacuation system completed as a result of research and testing completed the technical difficulties to adopt for mass-produced motorcycles," improved output, muffling effect, further weight reduction and functional beauty.
At CB 750 FOUR, the ignition switch that was next to the tank went to the meter section. For the head pipe, it adopted for the first time a combination lock and and switch, and it became possible to handle the handle lock by key operation of the switch.
CB 350 FOUR up from 347 cc to 408 cc (cylinder inner diameter changed from 47 mm to 51 mm) engine. Fore-I / II, which was set from 40800 to 39800, corresponded by shortening the stroke from 50 mm to 48.8 mm.
A catalog on the top is 1974 and the bottom is March 1976 (late). You are the wind. I like you. Changes in catch phrases are also famous. In 1986, Foreign-I / II of 398,000 was added, and the variation became three kinds. Two in the center in the lower row are I / II, and running with moving pictures becomes II standard handle specification. The 40800 version and Fore-I were semi-flat handles.
