The 1979 Honda CB650 Custom offers a different take on the standard CB650 formula, with styling cues aimed at the cruiser market. While sharing the same 627cc engine and 5-speed gearbox as the standard model, the Custom version features a more laid-back riding position and distinct visual elements. The engine, with its reliable performance and a top speed of 175 km/h, provides a comfortable and enjoyable ride for cruising. One notable difference is the smaller 14-liter fuel tank, which reduces the range compared to the standard CB650. However, the dual front disc brakes provide adequate stopping power. The ergonomics are tailored for a more relaxed riding experience, making it suitable for leisurely rides and showing off its unique styling. The CB650 Custom appeals to riders who prefer the aesthetics of a classic cruiser but appreciate the reliability and smooth engine of a Honda inline-four. It's a great choice for those who enjoy customizing their motorcycles and want a vintage platform with a distinctive look. The bike's overall design reflects the custom motorcycle trends of the late 70s.
