What Problems Does the 1991 Honda CB750 Have?
The 1991 Honda CB750, while generally a very reliable motorcycle, does have a few commonly reported issues that owners should be aware of, especially with aging examples. One of the primary concerns revolves around the electrical system. Over time, the wiring harness can degrade, leading to intermittent electrical faults, such as non-functioning lights, ignition problems, or charging system issues. The regulator/rectifier unit is also a known weak point and can fail, leading to overcharging or undercharging of the battery, which can cause further electrical damage.
- Carburetor Issues: The four individual carburetors, while providing smooth performance when in sync, can become difficult to keep properly tuned over time. This can manifest as rough idling, poor throttle response, or difficulty starting. Regular synchronization and cleaning are often necessary.
- Brake System Wear: Like any vehicle, the brake components, including pads, rotors, and brake lines, will wear out. For a 1991 model, it's essential to inspect these thoroughly. Leaking brake calipers or master cylinders can also occur due to age.
- Suspension Degradation: The fork seals can start to leak, and the damping within the shocks and forks can diminish with age and mileage, leading to a less composed ride. Rebuilding or replacing these components may be necessary for optimal handling.
- Cam Chain Tensioner: Some owners have reported that the automatic cam chain tensioner can become noisy or fail over time, leading to a rattling sound from the engine. While not always critical, it warrants inspection.
- Coolant Leaks: The liquid-cooled engine means there are coolant hoses and seals that can degrade over time, potentially leading to leaks. Regular inspection of the cooling system is recommended.
How long will the 1991 Honda CB750 last?
Based on owner data and general motorcycle longevity, a well-maintained 1991 Honda CB750 can realistically achieve and surpass 100,000 miles. Many owners report their CB750s are still running strong with well over 50,000 miles, attesting to Honda's build quality. The engine is particularly durable, often requiring only routine maintenance like oil changes, filter replacements, and valve adjustments. The primary weaknesses that appear over time are related to age and environmental exposure: rubber components (hoses, seals, tires) will degrade, electrical connections can corrode, and the finish on metal parts can deteriorate if not protected. However, with consistent care, including proper lubrication, timely servicing, and protection from the elements, the 1991 CB750 demonstrates exceptional long-term durability and can provide many more years of reliable service.
What Technology & Safety Features are Included?
The 1991 Honda CB750 is a product of its era, and as such, its technology, entertainment, and safety features are quite basic by modern standards. It does not feature any sophisticated built-in tech like navigation systems or advanced infotainment. Entertainment is limited to the sensory experience of riding the motorcycle. There are no driver-assistance features whatsoever, as these were not prevalent in motorcycles at that time.
- Safety Features: The primary safety features are inherent to its design and construction. It boasts a robust steel frame for structural integrity. The braking system consists of dual front disc brakes and a rear disc brake, offering competent stopping power for its weight and performance capabilities. The headlight and taillight system provides visibility, and the turn signals are standard. ABS (Anti-lock Braking System) was not an option on this model.
- Built-in Tech: The instrumentation is functional and straightforward, typically including an analog speedometer, tachometer, odometer, trip meter, and various indicator lights for fuel, oil pressure, turn signals, and high beam.
- Optional Features: Honda sometimes offered accessory packages, which might have included items like a windshield for improved wind protection, a rear luggage rack for carrying capacity, or heated grips for comfort in cooler weather. However, these were typically dealer-installed accessories rather than integrated factory options.
- Crash-Test Ratings: Motorcycles are generally not subjected to standardized crash-testing in the same way cars are. Therefore, there are no formal crash-test ratings available for the 1991 Honda CB750. Safety in a motorcycle context is more about the rider's skill, protective gear, and the motorcycle's inherent stability and braking performance. The CB750's design, with its balanced weight distribution and capable suspension, contributes to its stable ride, which is a fundamental aspect of on-road safety.
