The Honda CB s Legacy

The Honda CB s Legacy


Honda CB is a Series which spread and developed Year by year, changes of model and engine size was a kind of journey for Honda to be  one of the best Automobile manufacture in the globe.

From the 1950s to the 1960s, the best motorcycles in the world were models equipped with air-cooled parallel 2-cylinder engines around 650cc by British manufacturers such as Triumph and Norton.

Honda, which had already made its name in the 1960s in the 1960s, debuted the CB450 as the first large-displacement car in 1965, aiming for the world's fastest commercial vehicle.

was developed to compete with the 650cc class British car, which was the highest sports bike at the time. The engine displacement was as small as 450cc, but in order to make up for it, we adopted a GP racer-acquired DOHC, which was rare in commercial vehicles at that time. There are Type I for export 180 degree crank and Type II for domestic 360 degree crank. 

● Air-cooled 4-stroke DOHC 2-valve parallel 2-cylinder
● 444cc
● 43PS / 8500rpm
● 3.82kg-m / 7250rpm
● 187kg
● 3.25-18 ・ 3.50-18

The CB450 is also an air-cooled parallel 2-cylinder engine, but it was an ambitious design that compensated for the small displacement by increasing the rotation speed of DOHC.

However, it is a commercial failure because it cannot greatly exceed its rivals in terms of performance. 

1969 HONDA DREAM CB750 Four


Honda's first double cradle frame is equipped with the world's first 4-stroke OHC 4-cylinder engine. In addition to the overwhelming performance that the engine produces, it became an image leader that represents Japanese motorcycles with the beautiful sparkle of the four-wheel muffler that insists on front wheel disc brakes and four cylinders. 

● Air-cooled 4-stroke OHC 2-valve parallel 4-cylinder 
● 736cc 
● 67PS / 8000rpm 
● 6.1kg-m / 7000rpm 
● 220kg (dry) 
● 3.25-19 ・ 4.00-18

The approach that CB750Four debuted in 1969 took for the world's fastest was multi-cylinder. At that time, motorcycles were usually single-cylinder or two-cylinder, multi-cylinder engines were racers, and special ones such as Honda and MV Agusta dealt with.

However, Honda is a mass-produced commercial vehicle that employs an air-cooled straight four engine. The OHC has a displacement of 736cc, which greatly exceeds the rivals, and has achieved an overwhelming speed of 200km.

The car body is also at a high level, such as using a disc brake for the front brake to match its power.

High performance is evaluated with surprise and reigns as the world's fastest motorcycle, and it will become popular all over the world.
Of course, aiming at overthrow CB, rivals aiming for high performance by using Kawasaki Z1 in 1972, DOHC and large displacement are also appearing.

1978 Honda CB900F


Honda also countered with the CB750F / 900F, which adopted a 4-valve DOHC engine of the endurance racer / RCB series in 1978, but the limits of air cooling began to appear around this time.

new generation supersport that replaces CB750FOUR, which feeds back the know-how of endurance racers and RCBs, which boasted invincibility in endurance races around the world in the late 70s. The DOHC straight 4 engine is given a 4-valve head and is a high-performance one that easily exceeds 100 liters. The design composed of elegant lines was also impressive.

● Air-cooled 4-stroke DOHC 4-valve parallel 4-cylinder
● 901cc
● 95PS / 9000rpm
● 7.9kg-m / 8000rpm
● 232kg (dry)
● 3.25-19 ・ 4.00-18

1981 Honda CB1100R


In 1981, with the expansion of displacement, the ultimate one, the CB1100R, which was given luxurious equipment such as aluminum tanks and full cowls, the air-cooled CB will hand over the highest peak to the VF system of the water-cooled V4.

The engine bore for 900F has been expanded and powered up with high cams and semi-forged pistons. The ultimate CB equipped with a single seat, aluminum tank and half cowl.

● Air-cooled 4-stroke DOHC 4-valve parallel 4-cylinder
● 1062cc
● 115PS / 9000rpm
● 10.0kg-m / 7500rpm
● 233kg
● 3.50-19 ・ 130 / 90-18  

After that, the CBX750F of 1983 appeared as an air-cooled model, but it is a basic model.

The genealogy was developed into a CB750 in 1992 and became a long seller, but production ended in 2008. The history of air-cooled CB seems to have ended in about 40 years.

2010 Honda CB1100


However, in 10 years, the air-cooled CB new generation, CB1100, will be revived

A new generation air-cooled naked developed based on the keyword “Ouyo”. The newly developed air-cooled straight 4 is mounted on a body with beautiful but classic details.

● Air-cooled 4-stroke DOHC 4-valve parallel 4-cylinder
● 1140cc
● 88PS / 7500rpm
● 9.4kg-m / 5000rpm
● 243kg / 247kg
● 110 / 80R18 ・ 140 / 70R18 

The engine is powerful and easy to handle at medium and low speeds and has a unique feeling in order to embody “tasteful driving”, “joy of handling” and “joy of owning” with the keyword “hawking” A new model that is air-cooled based on the lower back of the CB1300 series is installed.

The classic and elegant styling body is the perfect size for a Japanese physique, and the front and rear wheels are 18-inch wheels for easy and relaxed handling.

The tradition that has been refined from CB750Four is certainly inherited in the 21st century by CB1100.
