The 1981 Honda CB900F, known as the Bol 'D Or in some markets, is a classic Japanese sport-touring motorcycle. Produced from 1979 to 1983, it featured a naked sportbike body style powered by a potent 901cc air-cooled inline-four engine. Its popularity stemmed from its blend of performance, comfort, and Honda's renowned reliability. Pricing varied but it was positioned as a premium offering for its era.
The Good
The 1981 Honda CB900F excels with its exhilarating inline-four performance and legendary Honda reliability. Its comfortable riding position and robust build appeal to practical riders, while its classic sportbike styling and engaging handling satisfy the emotional desire for a classic machine.
The Bad
Potential owners of the 1981 Honda CB900F should watch out for aging electrical components, particularly the rectifier/regulator and starter solenoid. Carburetor synchronization can be finicky, and signs of general wear and tear on a vintage machine are common.

What Problems Does the 1981 Honda CB900F Have?
The 1981 Honda CB900F, while generally known for Honda's characteristic reliability, is a vintage motorcycle and thus has potential issues common to its age. One of the most frequently reported problems pertains to the electrical system. The rectifier/regulator unit is notorious for failing, leading to charging system issues, battery drain, or overcharging, which can damage the battery and other electrical components. Early 1980s Hondas often used a less robust rectifier design. Another electrical concern can be the starter solenoid, which can become sticky or fail, preventing the engine from cranking.
Carburetor issues are also common. Due to age, rubber intake boots can crack, leading to air leaks and rough idling or poor performance. The four Keihin carburetors require meticulous synchronization for optimal running, and over time, internal components like jets or float needles can wear or become fouled, necessitating cleaning and rebuilding.
The Pro-Link rear suspension, while advanced for its time, can develop issues if not maintained. The shock absorber's damping can degrade, and the linkage bearings can wear, requiring replacement. On a bike of this age, general wear and tear are expected. This includes the clutch, brake components, and the exhaust system, which may show signs of rust or damage. While there aren't widespread recalls specifically tied to catastrophic failures on the 1981 CB900F, routine maintenance and proactive replacement of known wear items are crucial for long-term reliability. Owners should be particularly vigilant about the condition of the charging system and ensure regular carburetor maintenance. Model year variations are minimal within this specific generation of the CB900F, with most issues being age-related rather than specific design flaws for 1981.

How long will the 1981 Honda CB900F last?
With proper and diligent maintenance, the 1981 Honda CB900F can achieve well over 100,000 miles, with many owners reporting their bikes surpassing the 150,000-mile mark. Honda's robust inline-four engine is inherently durable. However, the long-term durability is heavily influenced by how the motorcycle has been cared for. Neglected maintenance, especially regarding the electrical system (rectifier/regulator) and regular carburetor servicing, can lead to premature failures of these components. The chassis and suspension components also wear over time, but these are generally replaceable. The core engine and transmission are known for their longevity, making the CB900F a testament to Japanese engineering when treated with respect.
What Technology & Safety Features are Included?
The 1981 Honda CB900F represents a period when motorcycle technology was focused on core mechanical function rather than electronic sophistication. As such, it lacks the extensive technology, entertainment, driver-assistance, and advanced safety features found in modern motorcycles.
Built-in Tech: The primary technology present is mechanical. This includes the reliable inline-four engine, a 5-speed transmission, and a chain final drive. The ignition system is typically a breaker-point or early electronic ignition, depending on the exact build date and market. The instrument cluster is analog, featuring a speedometer, tachometer, fuel gauge, and indicator lights for turn signals, high beam, and neutral. The braking system utilizes hydraulic discs, which were considered advanced at the time.
Entertainment: There is no integrated entertainment system; the riding experience and the engine's sound are the primary forms of auditory engagement.
Driver-Assistance: No driver-assistance features are present. The rider is solely responsible for operating the vehicle.
Safety Features: Safety features are basic and mechanical. The dual front disc brakes and single rear disc provide competent stopping power for the era. Lighting includes a headlight, taillight, and turn signals. The robust frame and suspension contribute to stability. However, features like ABS (Anti-lock Braking System), traction control, or advanced rider modes are absent.
Optional Features: Optional features were limited and typically aftermarket additions or dealer-installed accessories. These might include different windshields or fairings for improved wind protection (like on the Bol 'D Or variant), luggage racks, or different exhaust systems.
Crash-Test Ratings: Motorcycles, especially from this era, are not subjected to standardized crash-test ratings in the same way cars are. Safety is primarily dependent on the rider's skill and adherence to road safety practices.
