Honda C125A Super Cub Parts & Accessories

The Honda C125A Super Cub carries the legacy of one of the most enduring motorcycle designs in history, combining an overhead cam single-cylinder engine with a step-through frame that prioritizes accessibility and fuel economy. The Super Cub platform uses modern fuel injection and suspension geometry on current production while retaining the classic silhouette that defined urban commuter motorcycles for decades. Enthusiasts who restore or upgrade the Super Cub find a surprisingly active aftermarket covering period-correct OEM replacements and mild performance enhancements. Keeping one of these machines in top condition requires a reliable source for carburetors, ignition components, drive chains, and suspension hardware.

Popular Upgrades

K&N replacement air filters are a common first upgrade on Super Cub engines, improving airflow with a washable element that outperforms the OEM paper filter over time. Vance and Hines and Emgo produce slip-on exhaust systems that fit the small-displacement single and reduce weight while improving exhaust note. Avon and Metzeler tires in the correct rim diameter improve wet-weather grip compared to economy OEM tires. Barnett clutch kits and NGK iridium spark plugs are essential maintenance parts for any high-mileage Super Cub.

Performance and Handling

The Super Cub's semi-automatic transmission and low seat height make it forgiving for new riders, and suspension upgrades focus primarily on improved shock absorber damping for loaded or two-up riding. Progressive Suspension rear shocks add load-carrying capacity without raising seat height beyond comfort. Front fork oil replacement with a slightly heavier viscosity oil reduces dive under braking and improves feedback on rough pavement. Taller gearing via a larger rear sprocket lowers highway cruising RPM for improved fuel economy on longer commutes.

What Engine Is in the Honda Super Cub 125?

The modern Honda Super Cub 125 uses a fuel-injected 125cc single-cylinder overhead cam engine producing approximately 9.7 horsepower and 10.9 Nm of torque. The engine traces its architecture to the original OHC design Honda pioneered in the late 1950s, updated with modern fuel injection, programmed ignition, and improved thermal management. The engine's long stroke design favors low-RPM torque, making it well-suited for stop-and-go urban riding and mild two-up use.

How Long Do Honda Super Cub Engines Last?

Honda Super Cub engines are widely regarded as among the most durable small-displacement motorcycle engines produced, with many examples accumulating 50,000 to 100,000 kilometers with basic maintenance. The key maintenance items are regular oil changes every 3,000 kilometers, valve clearance adjustments at the specified interval, and timely chain replacement before stretch causes accelerated sprocket wear. Clean air filtration is critical given the simple carburetor or injector calibration on these small-displacement engines.
