Discover the Advancements That Honda Implemented in the Engine of the CB125F 2026, Focused on Efficiency, Technology, and Low Environmental Impact. Technical Details Reveal Why the Model Is a Reference Among Urban Small Displacement Motorcycles.
The Honda Launched the New CB125F 2026 in 2025, Focusing on Technical Improvements in the Engine, Aimed at Energy Efficiency, Mechanical Durability, and Low Maintenance Costs.
The model, already available in European markets, features a 124 cm³, four-stroke, single-cylinder engine with a single overhead camshaft (SOHC) and air cooling.
This engine was designed with a bore of 50 mm, a stroke of 63.1 mm, and a compression ratio of 10.0:1.

The Toyota Hilux is R$ 75.5 thousand cheaper and bets on the 2.8 turbodiesel engine with up to 204 hp and 50.9 kgfm to catch up with the VW Saveiro, which leads with 4,472 sales.
-
The new Renault Koleos has a screen exclusively for the passenger that is invisible to the driver, heated rear seats, and 29 assistance systems, but its Chinese competitors cost R$ 40,000 less and deliver more power.

The car stored for 38 years: when opening the barn door, what appears is breathtaking and looks like a scene from a movie!
-
Fiat works miracles in the Brazilian market, lowers the price of its 0 km hatch to R$ 69,990, reestablishes the model as the cheapest car in the country, and reignites the battle against Kwid and C3.
With these parameters, the system delivers up to 8 kW (approximately 10.9 horsepower) at 7,500 revolutions per minute and torque of 10.9 newton-meters at 6,000 rpm.
These configurations meet urban use with a focus on quick responses and economy.
Electronic Fuel Injection eSP and Efficient Consumption
The engine of the Honda CB125F 2026 is powered by electronic fuel injection of the PGM-FI type (Programmed Fuel Injection), responsible for precisely controlling the fuel dosage, optimizing consumption and pollutant emissions.
The system also includes the Enhanced Smart Power (eSP) technology, which reduces internal friction and contributes to the durability of components.
Among the features incorporated by eSP technology are the offset cylinder and the piston with oil jet cooling.
These features help maintain stable engine temperature and increase its longevity.
The technical result is an estimated average consumption of 66.7 km/l, measured by the WMTC (Worldwide Motorcycle Test Cycle), with an autonomy of over 700 km, considering the 11-liter tank.
Start&Stop System and Euro 5+ Standard
One of the features incorporated into the engine of the CB125F is the Start&Stop system, also known as Idling Stop.
This function automatically shuts off the engine at stops, such as at traffic lights, and restarts when the clutch is engaged.
The goal is to reduce fuel consumption and emissions in urban trips.
The new version of the model is also certified according to the Euro 5+ environmental standard, which establishes strict limits for gas and noise emissions.
According to manufacturer data, the CO₂ emission level of the CB125F 2026 is approximately 32 g/km, while the measured noise level ranges between 67 and 68 decibels, below the limits of current European legislation.
Transmission and Mechanical Structure
The engine is coupled to a five-speed manual transmission, with a multi-plate oil-bath clutch, designed for smooth and progressive shifts.
The final transmission is made by sealed chain of type 428, known for requiring less frequent maintenance and exhibiting greater resistance to corrosion.
With a lubricating oil capacity of 1 liter, the CB125F engine’s crankcase features a simple architecture, contributing to lower maintenance costs.
The total weight of the motorcycle is 117 kg, which also aids in fuel economy and performance in urban environments.
Technical Comparison with the Previous Version
The CB125F model had already undergone an update in 2021, when it received weight reduction, a digital dashboard, LED headlights, and improvements to the structure.
The 2026 edition maintains these features and adds the Start&Stop system, improvements in energy efficiency, and adaptations that align the project with stricter environmental standards.
The mechanical configuration remains focused on simplicity and reliability.
The use of air cooling eliminates the need for a water pump, radiator, and other elements typical of liquid systems, favoring practicality for everyday use.
Efficiency for Urban Mobility
The architecture of the engine of the Honda CB125F 2026 reflects a design aimed at urban use and frequent commuting.
The focus is on fuel efficiency, low pollutant emissions, and accessible maintenance.
Moreover, the system features conventional suspension adapted for urban terrain and 18-inch alloy wheels, contributing to a balance between comfort and handling.
According to technical analyses and data released by the manufacturer, the CB125F ranks among the entry-level models with the best consumption efficiency in the 125 cm³ segment.
The application of Start&Stop in motorcycles with manual transmission represents a technical advancement still uncommon in this displacement class.
Main Technical Specifications
Specifications of the Honda CB125F 2026 Engine:
- Displacement: 124 cm³
- Type: Single-Cylinder, 4-Stroke, SOHC, Air-Cooled
- Power: 8 kW (10.9 hp) at 7,500 rpm
- Torque: 10.9 Nm at 6,000 rpm

These characteristics place the engine of the CB125F among the most technically updated in its category, focusing on practical application and environmental compliance.
With the introduction of advanced features such as the Start&Stop system in a small displacement model with a manual transmission, will this innovation represent a new standard of demand for urban motorcycles in Brazil?
Esse é mais um atrativo para adiar um pouco os planos de se adquirir uma moto EV (“elétrica”). É a engenharia mecânica automotiva mostrando que “sempre é possível melhorar o produto”.
Só será útil pras nos se vier com preço competitivo
Melhor moto fz15 Yamaha…tenho uma 2024 não deixa nada a desejar,Honda já foi a época… qualidade caiu muito
Concordo plenamente com vc! . comprei uma fan 2025,e com 4 meses de uso ,caiu parafuso da seta ,Vasamento no sensor de marcha lenta, fora a transmissão q quando eles tiraram a folga ,voltou dando tranco. Na próxima vou de Yamaha!! 😁
Honda só tem nome a quslidade caiu eu sgora so compro suzúk vc não VR esta moto em oficina sem contar q ela é confortavel. Honda nunca mais
