Overview

Introducing the 1981 Honda CBX – a motorcycle that daringly defied convention and set the standard for performance in the custom-cruiser category. With its bold styling, unmatched engineering, and a six-cylinder engine that was simply ahead of its time, the CBX quickly became a symbol of Honda’s innovative spirit. As a flagship model in the early 1980s, it carved out a niche for riders who craved both style and substance, marrying the aesthetics of a cruiser with the raw power typically reserved for sport bikes. The CBX’s unique blend of performance and comfort has earned it a dedicated following among motorcycle enthusiasts, making it a sought-after classic in today’s market. At the heart of the 1981 Honda CBX lies a groundbreaking in-line six-cylinder engine, boasting a displacement of 1046cc. Producing a robust 100 horsepower at 9,000 RPM, this powerhouse propels the motorcycle to an exhilarating top speed of 222 km/h (137.9 mph). The engine’s design is not just about power; it features a compression ratio of 9.3:1 and four valves per cylinder, ensuring that the CBX delivers a thrilling riding experience with smooth acceleration and impressive torque. Riders will appreciate the responsive 5-speed gearbox that, combined with a chain final drive, provides a direct connection to the road, allowing for effortless shifts and control. While the air-cooled engine offers a classic touch, it also adds a layer of simplicity and reliability that many modern bikes sometimes lack. The 1981 CBX is more than just its engine; it boasts a host of features that enhance the riding experience. The dual disc brakes at the front provide exceptional stopping power, ensuring that riders can manage the bike's speed with confidence. The single rear disc reinforces this capability, offering a balanced braking performance. With a weight of 274 kg (604 pounds) and a fuel capacity of 24 liters (6.34 gallons), the CBX strikes a fine balance between stability and agility on the road. Its stylish lines and muscular stance, paired with a comfortable riding position, make it a striking presence on any ride, whether cruising through city streets or embarking on long journeys. **
