Honda C70 Super Cub vs. Honda C125 Super Cub: A Classic Meets Modern Evolution
The Honda Super Cub has been a staple of world wide two-wheeled transportation since its inception in the late 1950s. The most iconic and longest running version, the C70, had laid the groundwork for what would become one of the best-selling motorcycles (let alone vehicles) of all time. (As of writing this, over 100 million units have been sold)
Fast forward to today, and we have the Honda C125 Super Cub, a modern interpretation of this classic. This post will explore the differences between these two models, focusing on engine displacement, fueling, suspension, handling, chassis improvements, and cost.
Engine and Displacement
C70 Super Cub
The Honda C70 was powered by a 72cc, single-cylinder, four-stroke engine. This small displacement was sufficient for urban` `commuting and short-distance travel while providing a balance of performance and fuel efficiency. It’s anemic by today’s standards. Putting down a paltry 6hp, but it’s a Honda and it’s reliable.
Most, but not all C70’s are offered in electric start, but all do offer a kickstart for a backup in getting the motor going. The engine on the C70 is one that has been shared with a variety of mini bikes within the Honda range in the 60’s, 70’s and 80’s.
The Z50, CT70, ST90, CT90, and CT110, bikes shared the basic engine design as the Cub, all with varying bore and stroke differences. This short list, doesn’t include the mini quads as well. This is a short list of the past generations of bikes that all shared the same engine and design of the C70 engine.
C125 Super Cub
In a stark contrast, the Honda C125 features a larger 124cc, 9-ish HP single-cylinder, four-stroke engine, which feel enormous in comparison to it’s older sibling. The increase in displacement provides improved acceleration and better performance, all while still maintain it’s epic efficiency, especially when carrying a passenger or cargo. This makes the C125 more versatile for modern-day commuting, where higher speeds and greater power may be necessary. all C125 engines are offered in electric start, but none are offered with a backup kick starter. Thus, having a dead battery does mean a bit more fiddling to get the engine going.
The new supercub does share the engine with other bikes within the mini motor line up, but it’s a stark difference in numbers compared to it’s predecessor.
The MSX125 Grom, Monkey 125, Trail 125, the new Dax125 (currently Europe and Asia only) The ANF 125, and the CRF110 also share basic engine design to the new C125, but the numbers are far less in comparison to the older Cub.
Engine Fueling
C70 Super Cub
The C70 utilized a simple carburetor system for fuel delivery, which was reliable and easy to maintain. Carburetors are less complex than modern fuel injection systems but can require more frequent tuning and maintenance to ensure optimal performance. Especially where elevation changes and winterization comes into play.
Modification of fueling is arguably simpler, as you can find the carburetor jets of varying sizes OR replace the carb for a larger one entirely.
C125 Super Cub
The C125, on the other hand, is equipped with a fuel injection system, which provides more precise fuelling and improved fuel economy. This modern technology not only enhances performance but also reduces emissions, making the C125 a more environmentally friendly option.
Modification of fuel injection requires a little more work, as you’d need to alter the ECU to change the parameters and/or programming to provide a leaner or richer condition (more or less fuel based on demand)
Suspension and Brakes
C70 Super Cub
The suspension on the C70 consisted of leading link front and dual shock absorbers at the rear. While effective for its time, the suspension was basic and offered limited adjustability. Braking power was provided by front and rear 100mm drums actuated by cables. They did a sufficient job at slowing down the bike and rider, but often results in longer braking distances compared to modern disc brakes. If you’ve ever ridden a C70 and used the brakes, you’re very aware of the Honda Cub hop, as the front end rises due to the suspension design.
C125 Super Cub
The C125 features an upgraded suspension system with telescopic forks in the front and twin shock absorbers in the rear. The new setup is designed to offer better handling, improved comfort, and enhanced stability, particularly when navigating urban environments with uneven pavement. The C125 is also equipped with a front hydraulic disc brake system with a single channel ABS. Offering better stopping feel and modulation when it comes to slowing down or regulating speeds.
Handling
C70 Super Cub
The compact size and lightweight nature of the C70 made it nimble and easy to handle, perfect for city riding. However, its leading link front suspension with it’s often worn out suspension bushings, and it’s pressed steel frame can sometimes hamper performance especially at higher speeds. Often, with worn out front leading link suspension bushings, there is often side to side play on the wheel. Often mistaken for worn wheel bearings, it’s usually the cause of the suspension bushings.
C125 Super Cub
The C125 maintains the lightweight design but benefits from improved handling characteristics thanks to its steel framed backbone and upgraded suspension. The new model offers a more stable ride, particularly at higher speeds and on varied road surfaces, making it a better choice for diverse riding conditions.
Chassis Differences and Improvements
C70 Super Cub
The C70’s chassis was simple, a pressed steel frame, a stamped steel swing arm, the bike was strong yet relatively heavy. It provided a solid foundation for the bike but lacked any modern refinements.
C125 Super Cub
The C125 has a modernized tubular steel chassis along with an aluminum rear swingarm, which is lighter and more rigid, all this creates much improved handling and ride quality. The overall design and dimensions also incorporates a more comfortable seat and ergonomic improvements, making longer rides more enjoyable. Additionally, the C125 has a more contemporary aesthetic, blending classic styling with modern design elements.
Cost Comparison (Adjusted for Inflation)
C70 Super Cub
When it was first released in the 1970s, the Honda C70 had a price tag of approximately $500. Adjusting for inflation, that equates to roughly $2,500 today.
C125 Super Cub
The Honda C125 Super Cub, released in recent years, typically retails for around $3,600. While this may seem more expensive than the adjusted price of the C70, it’s important to consider that the C125 offers modern technology, improved performance, and enhanced comfort that the C70 simply could not provide.
Whichever you decide to go with,
The Honda C70 Super Cub and the Honda C125 Super Cub represent two different eras of motorcycle design and technology. The C70 stands as a beloved classic with its simple charm and reliability, while the C125 has modern advancements in performance, handling, and efficiency.
Ultimately, choosing between the two comes down to personal preference and more so availability: If you’re like me, and opt for nostalgia and simplicity of the C70 or want the advanced features and capabilities, and arguably the reliability of the C125. You really can’t go wrong with either model.
