Honda has stunned riders with a smarter twist on the CB300F Twister, and this one runs on petrol, ethanol, or any blend of both! Delivering a 293.5cc engine displacement, an output ranging from 24.5 to 24.7 CV, and 25.6 to 26.2 Nm of torque, could flex-fuel setups be the future of everyday motorcycles? Here’s what riders need to know now.
What Is Flex-Fuel?
In simple terms, a flex-fuel engine is designed to run on more than one type of fuel—typically a blend of petrol and ethanol (such as E85).
Instead of requiring a dedicated engine variant for each fuel type, Honda FlexOne technology allows riders to fill up their tanks with petrol, ethanol, or any combination of the two. The motorcycle’s internal computer dynamically adjusts combustion processes on the fly, making multi-fuel commuting seamless for the rider.
How the System Works
Wondering how the new flex-fuel system works behind the scenes? It relies on smart electronic integration:
- Fuel Detection: Electronic fuel injection sensors instantly detect the proportion of ethanol versus petrol present in the fuel system.
- ECU Calibration: The Engine Control Unit (ECU) instantly recalibrates ignition timing and fuel delivery to optimize performance for whatever mixture is in the 14.1-litre tank.
- Combustion Optimization: Because ethanol burns differently than pure gasoline, the engine management system automatically scales parameters to ensure smooth power delivery without manual user intervention.
Performance Numbers
When comparing output figures across fuel types, ethanol yields a marginal performance advantage:
| Spec | Petrol | Ethanol |
|---|---|---|
| Power | 24.5 CV / 24.5 bhp | 24.7 CV / 24.7 bhp |
| Torque | 25.6 Nm | 26.2 Nm |
| Engine | 293.5cc single-cylinder | 293.5cc single-cylinder |
While the operational differences are subtle, running on ethanol provides a minor bump in peak torque and horsepower.
Mileage and Efficiency
Real-world range and fuel efficiency depend heavily on local fuel pricing, riding style, and the precise blend ratio in your tank. While pure petrol typically offers higher energy density per liter, ethanol-blended options burn cleaner and can offer cost efficiencies in markets where alternative fuels are heavily supported. Real-world testing figures for urban commuter cycles hover around respectable efficiency brackets for a lightweight 300cc streetfighter, though actual numbers vary by conditions.
Features and Updates
The 2027 model year update brings a substantial hardware and tech overhaul to the platform:
- USD Front Fork: Upgraded to a 38 mm Showa SFF-BP inverted front fork for improved handling.
- Safety Suite: Features dual-channel ABS as standard and Honda Selectable Torque Control (HSTC) for traction management.
- Emergency Stop Signal (ESS): Automatically flashes hazard lights during heavy braking to warn traffic behind you.
- Transmission: Mated to a 6-speed gearbox equipped with an assist-and-slipper clutch.
- Convenience Tech: Includes an optically bonded digital LCD console to cut glare, a USB Type-C charging port, and HISS (Honda Ignition Security System) immobilizer tech.
Why This Matters
As global emissions regulations tighten and alternative fuel infrastructures grow, automakers are looking for pragmatic bridges between traditional internal combustion engines and complete electrification. By refining a popular commuter platform with flex-fuel capability and advanced electronic rider aids (like traction control), Honda is demonstrating how multi-fuel compatibility can coexist with modern performance expectations.
Will It Launch in Other Markets?
The 2027 Honda CB300F Twister has officially debuted in Brazil—where alternative fuels like ethanol are widely integrated into daily transport. At present, there is no official confirmation regarding a launch in India or other global regions, leaving enthusiasts waiting to see if Honda will re-introduce the updated platform to local markets.

FAQs
What is Honda FlexOne technology? It is Honda’s proprietary fuel-management system that allows an engine to seamlessly run on petrol, ethanol, or any blend of both without manual adjustments.
Does the CB300F Twister make more power on ethanol? Yes, it yields a minor increase, jumping from 24.5 bhp on petrol to 24.7 bhp on ethanol, alongside a boost in torque.
Is the 2027 Honda CB300F Twister coming to India? As of now, the bike has only been released in Brazil, and no official India launch timeline has been announced.
What features were added in the 2027 update? Key additions include Showa upside-down front forks, HSTC traction control, an emergency stop signal, and an upgraded anti-glare digital instrument cluster.
Is flex-fuel better for efficiency? Efficiency varies based on fuel composition and costs; while ethanol burns cleaner, pure petrol typically offers greater energy range per volume.
