How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built primarily for engaging back-road and urban sport riding, with its charm coming from a free-revving inline-four rather than outright power.
- Built for
- The CB400 Super Four is a precise, mechanically refined naked sportbike that delivers its thrills through a silky four-cylinder engine and confident chassis rather than brute force.
- Not ideal for
- It is not the right choice for riders seeking long-distance touring comfort, large-capacity torque, or any off-road capability.
