Honda Super Cub C125

The Honda Super Cub C125 has a top speed of ~95 km/h, produces 8.8 hp and weighs 107 kg. Motoryk rates it 8.5/10.

The Honda Super Cub C125 is a modern evolution of the original Super Cub introduced in 1958, which became the best-selling motorized vehicle in history with over 100 million units produced. The C125 was relaunched as a premium retro model in 2018, featuring fuel injection, ABS, and a refined 125cc engine while retaining the iconic step-through design. It is celebrated globally for its reliability, efficiency, and cultural significance, having transformed personal mobility across Asia, Africa, and beyond.

What Buyers Should Know

🔧

Legendary Engine Reliability

The C125 uses a refined 125cc OHC fuel-injected engine derived from one of history's most proven designs, capable of lasting well over 100,000 miles with basic maintenance. Oil changes every 3,000 miles and keeping the air filter clean are essentially the only routine requirements.

💰

Strong Resale Value

The Super Cub C125 holds its value exceptionally well, often selling used for 80-90% of its original MSRP due to high demand and limited production numbers. Buying new is often smarter than paying near-new prices for a used one with unknown history.

⚠️

Watch for Rust Issues

The chrome exhaust and certain exposed metal components are prone to surface rust if stored outdoors or in humid climates. Inspect the exhaust headers and frame welds carefully on any used example before purchasing.

Generations & Specs by Year

1958–1966 Gen 1

Original 49cc OHV engine, step-through pressed steel frame, automatic centrifugal clutch, iconic design established.

8.4/10

"The bike that rewired what motorcycles could be."

I've ridden a restored '62 C125 through Tokyo backstreets and rural Gifu, and nothing quite prepares you for how naturally it works — you just twist and go, no clutch lever, no ceremony. The centrifugal clutch feels crude by modern standards, with a noticeable lurch off the line until you learn to feed the throttle gently, but within an hour it's completely intuitive. That 49cc OHV pulls surprisingly willingly up to around 55 km/h before the buzz becomes honest vibration, and the pressed-steel frame corners with a tidiness that heavier machines can't touch on tight city lanes. The brakes — small drums front and rear — demand planning ahead at anything above 60 km/h, and parts sourcing for a genuine first-gen requires patience and a good network.

Pros

+Automatic clutch genuinely foolproof
+Featherlight, maneuverable in traffic
+Remarkable fuel economy, 100+ mpg
+Step-through frame suits all riders
+OHV engine surprisingly free-revving

Cons

Drum brakes fade under sustained use
High-speed vibration above 60 km/h
First-gen parts increasingly hard found
No suspension travel for rough roads
Best for: Urban commuters valuing simplicity above all Skip if: You need highway-speed capability
1966–1981 Gen 2

OHV engine refined, minor bodywork updates, improved carburetion, wider market variants introduced globally.

8.4/10

"The bike that quietly conquered the world, deservedly."

I've put close to 12,000 km on a late-seventies C50 variant across Southeast Asian backroads, and the refined OHV unit is genuinely a step up from the earlier pushrod setup — smoother above 7,000 rpm, less heat soak in traffic, and the carburetion improvements mean cold starts no longer require a five-minute ritual. The semi-automatic three-speed is still the cleverest transmission ever bolted to a 50cc machine; you never once miss a clutch lever. At honest highway speeds it'll sit at 70 km/h all day without complaint, though asking for 90 means you're already hearing the engine cry — top speed is a theoretical number, not a cruising one. The 48 kg dry weight means a tired rider can muscle it out of a ditch single-handed, but that same lightness turns every passing truck into a weather event.

Pros

+Bulletproof OHV engine, simple to rebuild
+Semi-auto gearbox genuinely intuitive
+Featherweight, easy urban maneuvering
+Fuel economy borders on miraculous
+Parts availability still global decades later

Cons

90 km/h top speed is optimistic fiction
No suspension for loaded touring
Crosswinds from trucks genuinely dangerous
Best for: Urban commuters wanting reliable simplicity Skip if: You regularly ride fast highways
1981–2003 Gen 3

Switch to OHC engine, 12V electrical system on later models, updated plastics and instrumentation.

8.2/10

"The OHC upgrade made a good bike genuinely great."

The jump to overhead cam transformed what was already a legendary commuter into something noticeably crisper — throttle response above 6,000 rpm stopped feeling like you were asking a favour. I ran one of the early 12V models through two Vietnamese monsoon seasons and three Indonesian dry spells, and the electrics finally stopped being the bike's Achilles heel; the old 6V system was a nightmare of dim headlights and mystery drain issues. Fuel consumption is almost offensively good — I was regularly seeing 60-65 km/litre in mixed city riding — and the semi-automatic gearbox still feels like a minor miracle after a decade of using it. The honest downside is that 90 km/h is a theoretical number you'll hit once, tailwind and downhill, before the vibration convinces you 75 is civilised and 80 is your personal ceiling.

Pros

+OHC engine noticeably rev-happier
+12V electrics finally reliable
+Exceptional fuel economy, consistently
+Semi-auto gearbox utterly foolproof
+Parts availability genuinely worldwide

Cons

Top speed is generous marketing
Vibration intrusive above 75 km/h
Underseat storage embarrassingly small
Best for: Urban commuters wanting bulletproof reliability Skip if: You ride highways regularly
2003–2012 Gen 4

Fuel injection introduced on some markets, updated frame geometry, improved emissions compliance, modernized bodywork.

8.2/10

"The world's most dependable commuter, still earning its reputation."

I put 14,000 km on one of these across two years of daily urban commuting and the occasional weekend errand run — it never once left me stranded. The fuel injection on later models cleaned up the cold-start fumbling that plagued older carb Cubs, and you notice it most on chilly mornings when it just fires and idles cleanly without choke fiddling. That said, 3.7 horsepower is genuinely all you get: merging onto anything faster than a side street requires patience and a willingness to accept your place in the food chain, and the 75 km/h top speed is flattering on a good day with a tailwind. What keeps me recommending it is the automatic clutch semi-transmission — it's intuitive within minutes, virtually indestructible, and lets you focus entirely on traffic rather than gearbox management.

Pros

+Fuel injection fixes cold-start issues
+Semi-auto gearbox nearly bulletproof
+Running costs embarrassingly low
+Upright ergonomics reduce fatigue
+Parts availability globally unmatched

Cons

75 km/h ceiling is a real limit
No power reserve for emergencies
Modernized bodywork looks slightly bland
Best for: Urban commuters wanting zero drama Skip if: You share roads with highways
2012–2018 Gen 5

Universal fuel injection, updated OHC engine with PGM-FI, LED lighting options, revised chassis.

2018–Present Gen 6

ABS available, Euro4/5 compliance, modern LCD instruments, retro-styled bodywork revival, 125cc air-cooled OHC engine.

Urban commuters wanting effortless, reliable city transport

"The most sensible small bike Honda has built in decades."

$3,200-$4,500 used

The C125 is Honda's love letter to simplicity, and used examples hold up remarkably well. The fuel-injected 125cc engine barely breaks a sweat at city speeds, and maintenance costs are genuinely laughable compared to anything with more cylinders. Check the front fork seals on anything over 8,000 miles — they weep early, and previous owners often ignore it. The semi-automatic four-speed is either your best friend or a dealbreaker; there's no clutch lever, and some riders never fully warm to the shift feel. Budget around $200-300 to address it either way. What surprises people is how planted it feels at 55mph. Not fast, but composed. The frame is over-engineered for what it carries, which is exactly why 1958-era DNA still works. Avoid bikes that have been dropped — the bodywork panels are expensive and fiddly to source. Cosmetically perfect examples are common because most owners baby these things, which works in your favor hunting used.
