Electrical System Aging and Corrosion
CriticalOlder motorcycles, including the Honda Super Cub from its 1958 debut through 2007, often experience issues related to aging electrical components and corrosion. Early models might have 6-volt systems, which are inherently less robust than modern 12-volt systems and more prone to charging problems and dim lights. Corrosion can affect wiring connections, switches, the magneto, and the regulator/rectifier (on later models), leading to intermittent electrical failures, weak spark, or non-starting conditions. Addressing these problems involves thorough inspection of the wiring harness, cleaning connections, testing the charging system, and potentially replacing components like the stator, coils, or points and condenser. This is a common long-term issue for classic motorcycles.
What to Check Before Buying
Owning a classic Honda Super Cub, whether it's an early 1958 Honda Super Cub or a later model up to 2007, can be a rewarding experience, but it requires understanding its unique needs and potential age-related issues. The Super Cub's enduring appeal lies in its mechanical simplicity, low running costs, and incredible practicality as a commuter machine. However, like any vehicle that has been in production for decades, specific attention must be paid to its maintenance and the potential for wear and tear on its components.
Regular maintenance is paramount for ensuring the reliability and longevity of your Honda Super Cub. This includes consistent oil changes, ideally using an oil suitable for classic motorcycle engines. The air-cooled nature of the engine means it relies on airflow, so ensuring the cooling fins are clean and unobstructed is important. Fuel system maintenance is critical, especially for carbureted models like the Honda Super Cub c100/102. Stale fuel can quickly degrade and clog the carburetor's internal passages, leading to starting problems and poor running. Using a fuel stabilizer when the bike is stored for any length of time, and draining the carburetor bowl if it will be unused for months, are good practices. Regular cleaning of the carburetor itself, perhaps annually or more often if you experience issues, is a wise preventative measure.
The braking system, typically drum brakes on classic Super Cubs, requires diligent attention. Drum brakes can be less effective than modern disc brakes, especially when wet or hot, and their performance degrades with wear. Inspecting the brake shoes regularly for thickness and the drum for scoring is essential for safety. Adjusting the brakes to ensure they are responsive without dragging is also key. Similarly, the chain and sprockets are vital wear items. Keep the drive chain clean, lubricated, and properly tensioned. A worn chain and sprockets can not only reduce performance but also pose a safety risk if they break. It is generally recommended to replace the chain and sprockets as a set when wear becomes apparent.
Electrical systems on older motorcycles can be a source of frustration. Corrosion is a common enemy, affecting wiring connections, switches, and grounding points. Periodically inspecting these areas, cleaning them, and applying dielectric grease can prevent many electrical gremlins. For models with older 6-volt systems, be aware that charging capacity is limited, and bulbs might be dimmer than you are accustomed to. If you experience weak charging or intermittent electrical issues, a thorough diagnosis of the stator, regulator/rectifier, and wiring harness is necessary.
When considering a purchase of a classic Honda Super Cub, whether it's a 1958 model or a 2007 Honda Super Cub, a thorough inspection is crucial. Check for signs of rust, especially in the fuel tank and frame. Inspect the suspension for play in the bushings and linkages. Examine the tires for age and condition. Listen for unusual noises from the engine and transmission. A test ride should reveal how the engine performs under load, how the clutch engages, and how effectively the brakes work. Pay attention to the condition of the bodywork and trim pieces, as some of these can be difficult to find and expensive to replace, particularly for very early models like the 1958 Honda Super Cub.
For owners in climates with high humidity, dust, or frequent rain, extra care should be taken. Corrosion protection for fasteners and metal parts is advisable. More frequent cleaning of the air filter and carburetor may be necessary. Brake systems should be checked even more often due to the potential for moisture and heat compromising their performance. Short trips and frequent starting/stopping cycles can also accelerate wear on certain components, so adapt your maintenance schedule accordingly. Ultimately, a well-maintained Honda Super Cub is a remarkably reliable and economical machine that offers a unique riding experience.
