Honda Super Cub C 125 2018–2021: Specs & Facts

The Machine's Character

The Super Cub C 125 brings Honda's 1958 step-through back to life, and it does it without turning the idea into a museum piece. The layout is still the original: an underbone frame, a 125 cc air-cooled single and a four-speed semi-automatic gearbox. Now there's fuel injection, an LED headlight, a keyless system and a front disc with ABS. It makes 10 hp and 8 lb-ft, and it weighs 243 lb (110 kg) fully fueled. On paper that's modest. The point is how honest the whole package is. Few bikes in the small-scooter world look this good at the curb or feel this uncomplicated to own.

This bike ages the way Honda buyers hope every bike will. It's reliable, it sips fuel at a rated 105 mpg, and there's almost nothing on it to go wrong or to fiddle with. The low seat, the light steering and the easy controls make it the right tool for dense city riding and for anyone who wants transportation with some charm. Now the caveat. Top speed is 67 mph (108 km/h), the tank holds only 1.0 gal (3.7 L), and it has no luggage system from the factory. If you need to haul things or cover highway miles, look elsewhere. For short urban hops, it's a pleasure.

The Truth on the Street

Over the years I've gathered a lot of owner talk on the C125: paddock conversations, chats at club nights, and the messages riders send me after living with one for a while. The picture is consistent. Owners enjoy it in town. The complaints start when they want to carry a second person, a bag, or run on faster roads.

The looks people stop you for

The styling comes up first and most often. Owners mention the sea-and-sky paint, the leg shields and the chrome, and how often strangers want to talk about it. After that, riders praise how easily it handles at walking pace and how long they go between small fill-ups. Several say the clutchless shifting makes stop-start commuting fuss-free.

One seat, one side cover

The most common gripe is the single seat. It rules out a passenger, and commuters call that a real omission. Storage is the other one. There's no underseat bin, only a small lockable side cover, so most owners end up adding a top box. Riders also say passing on fast roads takes patience, and a few find the narrow tires nervous at speed and in crosswinds.

Known issues

Rear drum brake can lock easily

brakes occasional

Under hard braking, the rear drum lacks ABS and can skid. Not a safety recall but requires smooth pedal modulation.
Keyless system battery drain

electrics rare

Some owners report that the keyless fob battery drains quickly, leading to occasional starting issues. Replacing the battery resolves the problem.
Brake hose banjo bolt corrosion

brakes occasional

On bikes used year-round, the brake banjo bolts can develop surface rust. A cosmetic issue but may require cleaning and protection.

Best scooter for NYC?

This is your bike. It's light, cheap to run and easy to park, and it's happiest on crowded streets. Just plan on adding storage, because it arrives with none.

Best motorcycle for Bay Area?

For cruising around San Francisco and turning heads at the coffee stop, it's a gem. On weekend ridge roads, though, 10 hp and a 67 mph top speed leave you wanting more.

Alternatives to the Honda Super Cub C 125

If this one isn't quite the fit, these are the bikes worth riding back-to-back against it.

Any price note compares both bikes at the same age — the youngest age both have on the used market — against this Honda Super Cub C 125. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
