Engine
The Honda CB 750 was equipped with an engine producing 75 horsepower and 65 Nm of torque, which is a very good indicator even for modern motorcycles. The motor was equipped with a valve drive system with a hydraulic compensator, which eliminates the need for constant adjustment and reduces the noise level. The engine has a long service life and reliability, but requires proper and high-quality maintenance. When saving on consumables and operating fluids, you may be faced with the need for expensive repairs.
Transmission
The gearbox installed on the Honda CB 750 has the same characteristics as the engine, being reliable, long-lasting and quiet. Gear shifting is smooth and soft.
The weak point of the motorcycle is the gear shift shaft, which fails when dropped on the left side. Versions released for the Japanese market most often suffered from rapid clutch wear. Replacing this unit is complicated by the fact that it differs from those installed on European Honda CB 750 models, which makes it extremely difficult to find.
Famous Japanese bikes – Honda CB 750
The classic, popular for over 50 years, is accessible and in demand among modern motorcycle enthusiasts. The Honda CB 750 series of bikes successfully combines the advantages of a 4-cylinder air-oil-cooled engine with old-school appearance elements.
Production began in 1969, with peak popularity in 1991. Production of the line continued until 2003. A special series called the CB 750 Special Edition was produced in 2007 and was only available for the Japanese market as an attempt to restart the production line. A special feature of the line is the silver color of the models.
The Honda SB 750 model managed to become a museum exhibit; the road motorcycle is the first representative of the superbike class.

Additional options and versions
The model intended for the American market was equipped with ineffective brakes with a front disc mechanism and a rear drum mechanism, and therefore they prefer to purchase versions of the Honda CB 750 with two disc mechanisms in the front and one in the rear. The braking systems of other versions are many times more powerful, which is their undoubted advantage.
It is worth noting that the manufacturer offers a wide range of additional equipment for tuning, but when choosing it, it is worth considering that the Japanese and European versions of the motorcycle differ from each other.
Characteristics of Honda CB 750
With its 4-cylinder engine, the Honda CB 750 made history as the world's first modern four-cylinder motorcycle. The sportbike is capable of reaching speeds of up to 200 km/h. It accelerates to 100 km/h in 3.9 seconds.

The European model features old-school looks, disc rear and dual front brakes.
The American one has a single disc brake in front and a drum brake in the rear, as well as a cruiser look.
The important advantages of the bike are:
- presence of an electric starter;
- double mirrors;
- comfortable fit;
- dual rear shock absorber;
- low noise and vibration levels during operation.
The Honda St 750 consumes 6.8 liters of fuel per 100 km. More accurate calculations depend on the technical condition of the motorcycle, the area of use and riding style.

Owner reviews
A distinctive feature of the Honda CB 750 is a comfortable and comfortable seat that allows you to carry a passenger. The engine runs silently, average fuel consumption is 6 liters per 100 kilometers at a speed of 100-120 km/h. Engine oil consumption is reasonable, the air-oil cooling system protects the engine from overheating.
Among the disadvantages, owners of the Honda CB 750 in reviews say that the suspension is too soft, and therefore motorists often replace the springs with new ones. The fork is quite soft and sometimes breaks, but there is nothing critical about it. When using low-quality oil, the clutch begins to slip when driving at speeds over 160 km/h and during intense acceleration. This drawback can be eliminated by using high-quality motor oil.
The owners note that the braking system, represented by a drum and disc mechanism, is quite sufficient for the motorcycle, despite the fact that it is often criticized. If necessary, the motorcycle stops quickly and confidently without skidding.
The Honda CB 750 can travel 700 kilometers or more per day without overheating the engine, confidently holds its course, and does not wander along the road. Acceleration from a standstill is smooth, without jerks, the maximum speed is 180 km/h. Owners note the presence of a limiter and excellent acceleration dynamics, which are maintained throughout the entire speed range.
Despite the motorcycle’s considerable dimensions, it handles well in traffic jams and heavy city traffic: owners note excellent maneuverability. The seat is quite low, but at the same time comfortable and comfortable, the transmission works excellently. The stated problems with finding spare parts are not justified: motorcyclists easily find the necessary components in specialized stores, noting their affordable cost in reviews.

The CB 750 was created on the basis of the model of the same name, released more than half a century ago. Despite certain pros and cons, the simple design of the model is quite reliable, and the retro design can be considered an advantage.
Modification of Honda CB750K7
The modified model “HONDA CB750K7”, which is the work of Danish craftsmen and lovers of classic bikes from the “Wrenchmonkees” salon, has become the object of our attention.
Like all modern motorcycle showrooms, Danish mechanics decided to add their own twist in the form of a chrome-plated body taken from the well-known Suzuki GS 400/425 bike. The landing was significantly lowered, engine power was increased to 836 cubic meters, Dunlop D401 tires give the CB750K7 an exceptionally brutal look.
A very colorful cafe racer that can satisfy the whims of any connoisseur of classic bikes.
