The 2025 Honda ST125 Dax combines nostalgic design with modern engineering, creating a perfect blend of fun and functionality. This iconic mini motorcycle returns to the American market after a 41-year absence, bringing its distinctive T-shaped frame and approachable riding experience to a new generation. With its air-cooled 124cc engine, semi-automatic transmission, and retro styling, the Dax offers surprising versatility for both urban commuters and recreational riders. Priced at $4,199, it delivers outstanding fuel economy (over 100 MPG), room for two passengers, and the unmistakable charm that has made the Dax a beloved part of Honda’s heritage since 1969.
The Legacy Reborn: Honda Dax’s Fascinating History
The Honda Dax story begins in the late 1960s, establishing itself as one of Honda’s most distinctive small motorcycles. The original ST models (known as CT70/Trail 70 in America) debuted in 1969, earning the “Dax” nickname in Europe due to its dachshund-like silhouette with an elongated profile.
From Past to Present
The Dax enjoyed popularity throughout the 1970s before withdrawing from European sales in 1981, continuing only in US and Japanese markets. After a long hiatus, Honda revived this cult classic in 2022 for European markets and now brings it to American shores for 2025.
This reintroduction is part of Honda’s strategy to expand its mini-moto lineup, with the Dax joining the Monkey 125 and MSX125 Grom as part of a trio of small-displacement, retro-styled motorcycles. The 2025 model honors the CT70’s legacy by incorporating modern engineering while maintaining classic design elements.
Why “Dax” Matters
What makes the Dax special is its blend of approachability and distinctive design. Its T-shaped pressed steel frame is not just a styling element but a functional part of the motorcycle that houses the fuel tank and wiring loom. This unique architecture, combined with its compact dimensions and chunky tires, creates an instantly recognizable silhouette that stands apart from conventional motorcycles.

Performance & Engine Specifications
The heart of the 2025 Honda Dax is its proven 124cc air-cooled single-cylinder engine, shared with other popular Honda minimoto models.

| Range | Approximately 240km (149 miles) | Excellent for commuting and day trips |
| Emissions | Meets Euro 5+ standards | Environmentally compliant |
Performance in Real-World Conditions
The Dax’s engine is designed for accessible performance rather than outright speed. With a claimed top speed of around 55 mph, it can push slightly higher (around 60 mph) with favorable conditions like a downhill stretch or tailwind. The engine’s strong torque characteristics mean that even with two riders, maintaining a 90 km/h (56 mph) cruising speed is achievable.
What truly stands out is the fuel efficiency. Honda claims 63.7 km/l (106.7 MPG) based on EPA testing, but real-world riding suggests this might be conservative. Riders report traveling approximately 90 miles on half a tank of the 1-gallon fuel capacity, suggesting exceptional economy approaching or exceeding 2 miles per ounce of fuel.
The semi-automatic transmission with centrifugal clutch is a distinctive feature that enhances the bike’s approachability. Without a clutch lever, riders simply select gears with the foot lever while the clutch engages automatically as the throttle is opened. This setup is particularly welcoming for new riders or those with limited manual transmission experience, removing one of the most intimidating aspects of motorcycle operation.

Handling Characteristics
The Dax’s handling is defined by its compact dimensions and thoughtful engineering. The wide, upswept handlebars combined with the 31mm upside-down forks provide easy, light steering that excels in urban environments. Despite its diminutive size, the bike maintains stability thanks to its fat 12-inch tires, which add sure-footed grip while preserving nimble agility.
The bike’s low center of gravity and modest 107kg (236 pounds) wet weight contribute to its approachable nature. With a seat height of 775mm (30.6 inches), most riders can easily place both feet on the ground at stops, boosting confidence for newer riders.
What truly distinguishes the Dax is its iconic T-shaped frame, which serves both form and function. This pressed-steel structure houses the fuel tank within the frame itself and contributes to the bike’s distinctive appearance while providing adequate rigidity for its intended use. The design contributes to the Dax’s uniquely proportioned silhouette that has earned it a devoted following.
Electronics & Dashboard Features
Although the 2025 Honda Dax embraces simplicity as part of its charm, it incorporates modern electrical components that enhance the riding experience.
Technology & Features
| Feature Category | Specification | Rider Benefit |
|---|---|---|
| Instruments | Compact negative LCD display | Clear visibility in various lighting |
| Headlight | LED | Bright illumination, modern efficiency |
| Taillight | LED | Enhanced visibility to following traffic |

The instrumentation of the Dax is deliberately minimal yet functional. The negative LCD display provides essential information including speed, odometer, fuel level, and gear position in a compact, easy-to-read format. For 2025, Honda offers an optional shift indicator display that enhances functionality by providing clear gear position information, particularly valuable given the bike’s semi-automatic transmission system.
The full LED lighting package is a modern touch that contrasts with the Dax’s retro styling. LED technology offers superior brightness, longevity, and energy efficiency compared to traditional bulbs, enhancing both safety and the bike’s contemporary appeal despite its vintage-inspired design.
The electrical system is designed with simplicity and reliability in mind, aligned with the Dax’s overall philosophy. The transistorized ignition ensures consistent starting, while the standard 12V system allows compatibility with common motorcycle accessories.
Comfort & Accessories
The 2025 Honda ST125 Dax balances its compact dimensions with thoughtful ergonomics and a range of accessories that enhance both comfort and utility.
Comfort Features & Available Accessories
| Feature Category | Specification | Rider Benefit |
|---|---|---|
| Seat Height | 775mm (30.6 inches) | Accessible for most rider heights |
| Seat Type | Dual straight with room for passenger | Versatility for solo or two-up riding |

Rider Comfort & Ergonomics
Despite its minimalist approach, the Dax offers surprising comfort for its size. The dual straight seat is designed to accommodate a rider and passenger, with a chrome grab rail providing security for the pillion. The wide, upswept handlebars create an upright riding position that remains comfortable during urban commuting and casual rides.
For 2025, Honda has expanded the comfort-enhancing accessory lineup with new heated grips particularly useful for riders in cooler climates. The addition of optional saddlebags increases the practicality of the Dax for daily use, addressing one of the few limitations of the minimoto platform.
The 775mm seat height is approachable for riders of various heights, and the bike’s narrow profile makes it even easier to place feet firmly on the ground at stops. This confidence-inspiring ergonomic setup contributes significantly to the Dax’s appeal for newer riders.
A thoughtful detail is the drive chain cover, which protects both the chain from weather exposure and riders/passengers from potential contact with the drivetrain-a practical safety feature that demonstrates Honda’s attention to detail.
Safety Features & Rider Protection
Safety features on the 2025 Honda Dax blend modern technology with the inherent advantages of its lightweight, manageable design.
Key Safety Elements
The single-channel ABS system operates on the front wheel, providing crucial anti-lock protection where it matters most without adding unnecessary complexity or weight. This system helps prevent front wheel lock-up during hard braking, particularly valuable on wet or loose surfaces.
The full LED lighting system significantly enhances visibility both for the rider and to other road users. The bright, modern lighting signature ensures the Dax is easily spotted in traffic despite its compact dimensions.
The low seat height and lightweight design contribute to safety by allowing riders to confidently manage the motorcycle at low speeds and when stopped. At just 107kg (236 pounds) wet weight, the Dax is manageable even for smaller or less experienced riders.
While minimalist in design, the negative LCD display provides clear information at a glance, allowing riders to monitor speed and other critical data without prolonged distraction from the road.
For additional peace of mind, Honda offers an unlimited-mileage, limited warranty for one year, with the option to extend coverage through HondaCare Protection Plans.
Real-World Scenario: Urban Commuting & Weekend Adventures
The Perfect Urban Companion
The 2025 Honda Dax truly shines in city environments where its compact dimensions, light weight, and nimble handling create an ideal urban runabout. With a tight 2-meter turning radius, the Dax can navigate congested streets and tight parking situations that would challenge larger motorcycles.
In real-world urban riding, the Dax’s 124cc engine provides sufficient power for quick starts from traffic lights and comfortable cruising at city speeds. The semi-automatic transmission proves particularly valuable in stop-and-go traffic, eliminating clutch fatigue while still providing the engagement of a conventional motorcycle.
Perhaps most impressive is the fuel economy. With real-world consumption potentially exceeding the claimed 106.7 MPG, urban commuters might find themselves refueling the 1-gallon tank less than once a week even with daily use. This exceptional efficiency makes the Dax an economical alternative to both public transportation and larger motorcycles.
Weekend Excursions
While primarily designed for shorter trips, the Dax is capable of more adventurous riding within its performance envelope. Its approximately 240km (149-mile) range on a full tank makes day trips entirely feasible. The comfortable, upright riding position remains amenable for longer rides, though highway cruising near the bike’s top speed may become tiring over extended periods.
The Dax’s approachable nature makes it particularly enjoyable on winding backroads where its light, responsive handling can be appreciated without requiring high speeds. For 2025, the addition of optional accessories like heated grips and saddlebags further enhances the Dax’s weekend adventure capabilities.

Frequently Asked Questions
Is the 2025 Honda Dax 125 good for beginners?
Yes. The Dax is excellent for beginners thanks to its low seat height, lightweight chassis, and semi-automatic transmission that eliminates clutch operation. The modest power output provides enough performance without being intimidating, while features like single-channel ABS add safety without complexity.
How fast does the Honda Dax 125 go?
The Honda Dax has a claimed top speed of around 55 mph, though riders report reaching slightly higher speeds (around 60 mph) with favorable conditions like downhill sections or tailwinds. It’s designed for urban riding rather than highway cruising.
What’s the difference between the Honda Dax and CT70/Trail 70?
While the Dax is inspired by the original CT70/Trail 70, the 2025 model features significant modern updates including a larger 124cc engine (vs. 70cc), fuel injection, disc brakes with ABS, LED lighting, and electric starting. The core design philosophy and T-shaped frame remain as homages to the original.
Is the Honda Dax worth the price?
For riders seeking a unique, retro-styled motorcycle with modern reliability, the Dax offers excellent value. Its exceptional fuel economy (over 100 MPG), Honda’s reputation for quality, and the bike’s distinctive character make it worth considering despite premium pricing compared to conventional 125cc motorcycles.
Can the Honda Dax carry a passenger?
Yes. Unlike some minimotos, the Dax is designed with a dual seat and passenger grab rail, making it suitable for occasional two-up riding. Honda states that even with two riders, the bike can maintain a cruising speed of 90km/h (56 mph).
How does the semi-automatic transmission work?
The Dax features a 4-speed transmission with an automatic centrifugal clutch. Riders change gears using a conventional foot shifter (heel-toe design) but don’t need to operate a clutch lever. The clutch engages automatically as the throttle is opened, simplifying operation especially for beginners.
What is the fuel economy of the 2025 Honda Dax?
The EPA rates the Dax at an impressive 106.7 miles per gallon. Real-world testing suggests this might be conservative, with some riders reporting even better efficiency in typical use. With its 1-gallon (3.8L) tank, the range is approximately 100-149 miles per fill-up.
My Experience Riding the 2025 Honda Dax 125
The Good Side
From the moment I twisted the throttle on the 2025 Honda Dax 125, I was greeted with a thumpy exhaust note that put a smile on my face – those little brap-brap-brap sounds at idle were exactly what this mini bike should sound like.
The ride quality impressed me immediately. Despite its small size, the suspension is remarkably forgiving over both big and small bumps, with well-damped twin shocks providing 4.7 inches of travel in the rear. I could hit neighborhood speed bumps at full throttle without worry – the shocks and fork simply absorbed the impacts without jolting me.
Fuel efficiency is absolutely incredible. Honda claims 106.7 mpg, but I think that’s conservative – I noticed I’d gone about 90 miles and barely used half of the 1-gallon tank. With a theoretical range of 150 miles between fill-ups, this little bike is incredibly economical.
The semi-automatic transmission is perfect for new riders or city commuting. Without a clutch lever, you simply close the throttle, shift up or down, and twist again4. It’s a brilliant halfway house between a manual and automatic that makes stop-and-go traffic much easier to handle.
The Bad Side
The seat, while visually substantial (taking up about 30% of the motorcycle’s appearance), is surprisingly stiff4. I expected it to be cushier given its size, though it’s still comfortable enough for 30-minute commutes.
The LCD dash can be frustratingly difficult to read when the sun hits it at certain angles. I often found myself struggling to see important information when riding toward the sun.
The four-speed transmission sometimes left me wanting more – I frequently reached for a fifth gear that wasn’t there, especially when cruising at 45-50 mph on flat roads. Upshifts and downshifts can also be jolting until you master the auto-clutch technique. You need to fully shut the throttle for smooth gear changes, and downshifts are particularly lurching.
Performance is adequate but not impressive. While I could push it slightly above 60 mph downhill with a tailwind, hills can reduce speed to under 40 mph. And if you’re carrying a passenger, performance noticeably diminishes.
Despite these minor drawbacks, the Dax 125 perfectly balances nostalgia and usefulness, making it an ideal bike for crowded cities while also being a friend-making machine wherever you go.
Expert Verdict: Should You Buy the 2025 Honda Dax 125?
Who Should Buy the Dax
The 2025 Honda Dax 125 represents a perfect blend of practical transportation and recreational enjoyment. It’s ideally suited for:
- Urban commuters seeking an efficient, easy-to-park alternative with exceptional fuel economy
- New riders attracted to its approachable height, weight, and semi-automatic transmission
- Motorcycle enthusiasts looking for a second or third bike with unique character and retro appeal
- Riders who occasionally travel with a passenger but primarily ride solo in urban environments
The Dax excels as a stylish urban runabout that delivers both practical transportation and genuine enjoyment. Its distinctive styling ensures it stands out in a crowded marketplace, while Honda’s reputation for reliability provides peace of mind.
Who Should Look Elsewhere
Despite its many charms, the Dax isn’t for everyone:
- Highway commuters needing sustained speeds above 55 mph
- Riders requiring significant storage capacity without adding accessories
- Those seeking cutting-edge performance rather than character and style
- Taller or heavier riders who might find the compact dimensions restrictive for longer journeys
Final Assessment
The 2025 Honda Dax 125 successfully captures the spirit of the original while delivering thoroughly modern performance, efficiency, and reliability. It represents a premium option in the 125cc class, justified by its unique character, quality construction, and the intangible joy it delivers.
For those who value distinctive design, approachable riding dynamics, and exceptional efficiency over outright performance, the Dax offers a compelling package that few competitors can match. It’s not just transportation-it’s a motorcycle that consistently delivers smiles per mile alongside its impressive miles per gallon.
Latest Updates: What’s New for the 2025 Honda Dax
The most significant news for the 2025 model year is the Dax’s introduction to the American market, arriving in Honda dealerships in October 2025. This marks the return of this iconic design to US shores after a decades-long absence.
Technical updates for 2025 include:
- Euro 5+ compliance through ECU refinements and enhanced emissions control systems
