What is the top speed of the Honda CB400?

The design top speed of the Honda CB400 second generation is 180 kilometers per hour, and it can reach a maximum speed of 190 without any modifications. Braking system of the Honda CB400 second generation: The front braking system of the Honda CB400 second generation consists of a pair of 296mm diameter floating drilled discs, abandoning the original Brembo four-piston hydraulic opposed calipers and replacing them with a similarly designed but Japanese-made Nissin product. Engine of the Honda CB400 second generation: The VTEC engine starts with a slightly sluggish feeling at 2500r/min, but performs more ideally at 3000r/min. This is due to the use of 120/60ZR17 front tires and wider 160/60ZR17 rear tires (originally 110/70-17 front and 140/70-17 rear). Shifting into second gear at 4500r/min does not show outstanding performance, requiring higher RPM to maintain stable steering, otherwise, there is some tightness when turning, possibly caused by the widened tires.
I used to ride a CB400, and its top speed can reach around 180 km/h. Of course, this was measured under ideal conditions, such as a straight highway, tailwind, and a lightweight rider. In reality, many factors can affect the actual speed. For example, insufficient tire pressure can reduce the speed by about 10 km/h, and a loose chain can also drag performance down. I remember the 1998 SUPER FOUR version was particularly fierce—when revved to the limit, the four-cylinder roar sounded like a racing team zooming past. But I’d advise against pushing it to the limit, as the stock tires’ grip noticeably weakens above 170 km/h. Regular maintenance, like cleaning the air filter and spark plugs, is crucial. Too much carbon buildup can make even hitting 150 km/h a struggle. With motorcycles, speed matters, but making it back alive matters more, right?
