Honda CB300F Flex-Fuel

The Honda CB300F Flex-Fuel, now on sale in India as a BS6 Phase 2 compliant model, presents a pragmatic approach to the 250-300cc streetfighter segment. Its primary strength lies in a combination of low kerb weight and a torque-rich engine, making it an exceptionally manageable and responsive motorcycle for urban environments. While its headline feature is the ability to run on E20 to E85 ethanol-blended fuel, its real-world appeal is in its practical feature set. It competes directly with established models like the Suzuki Gixxer 250, Bajaj Dominar 250, and the performance-oriented KTM 250 Duke.

Honda CB300F Flex-Fuel Overview

Engine, Performance and Mileage

The heart of the Honda CB300F is a 293.52cc, 4-valve, oil-cooled, single-cylinder engine. This BS6 Phase 2 unit is now configured for flex-fuel compatibility, allowing it to run on petrol blended with ethanol from 20% (E20) to 85% (E85). The power output is rated at 24.4 PS at 7500 rpm, while the peak torque of 25.6 Nm is delivered at a relatively low 5500 rpm. This torque delivery is the engine's defining characteristic. In urban traffic, it translates to a highly tractable nature, allowing the rider to pull cleanly from low speeds in higher gears, thereby reducing the need for frequent gear shifts. The 6-speed transmission, aided by a slip and assist clutch, further lightens the clutch action, making it a comfortable companion in stop-go conditions. 

On the highway, the motorcycle can comfortably cruise between 100-110 kmph, with the sixth gear acting as an overdrive. However, vibrations become noticeable past this range, indicating the engine is operating outside its comfort zone. Fuel efficiency on standard E20 petrol is expected to be in the 30-35 kmpl range, though running on higher ethanol blends will likely result in a quantifiable decrease in this figure.

posture comfort

The ergonomics of the CB300F are engineered for the urban rider. The riding posture is upright with a slight forward lean, created by the wide, single-piece handlebar and moderately rear-set footpegs. This posture strikes a sensible balance, being comfortable for daily commutes without being too relaxed for spirited riding. The 789mm seat height is accessible to a wide range of riders, and the narrow profile of the seat-tank junction allows for an easy reach to the ground. The single-piece seat itself offers adequate cushioning for rides up to an hour or two, but its relatively compact size might feel restrictive on longer journeys. 

Pillion comfort is acceptable for short city hops, with well-positioned grab rails, but the limited space and high-set footpegs make it less ideal for extended touring. With a 14.1-litre fuel tank, the motorcycle offers a practical range of over 400 kilometres on a full tank of petrol. The oil-cooled engine manages heat well in traffic, preventing excessive discomfort for the rider during prolonged stops.

handling ride quality

The CB300F is built on a diamond-type frame, suspended by a non-adjustable golden USD (Up-Side Down) fork at the front and a 5-step preload-adjustable monoshock at the rear. This suspension is tuned for a balance between comfort and composure. It effectively absorbs most undulations and broken patches typical of Indian city roads without feeling overly soft or wallowy. The motorcycle’s most significant handling advantage is its low kerb weight of just 153 kg. 

This makes it incredibly agile and effortless to manoeuvre through dense traffic, a trait where it scores significantly higher than heavier competitors like the 180 kg Bajaj Dominar 250. In corners, the chassis feels neutral and predictable, supported by the wide 150/60-R17 rear tyre which provides a stable contact patch. Braking duties are managed by Nissin callipers, with a 276mm disc at the front and a 220mm disc at the rear, governed by a dual-channel ABS system. The braking offers progressive feedback and sufficient stopping power for the motorcycle's performance envelope, inspiring confidence without the aggressive initial bite found on some of its European rivals.

Design

Visually, the CB300F adopts an aggressive, mass-forward streetfighter stance with sharp tank shrouds and a muscular fuel tank. The all-LED lighting package, including a sharp headlamp, sleek indicators, and a V-shaped tail lamp, lends it a modern and premium appeal. The rider’s interface is a fully digital, negative LCD instrument cluster that provides a comprehensive set of information, including a gear position indicator, trip meters, clock, and real-time fuel consumption data. The switchgear quality is functional and up to Honda standards. Where the CB300F stands out is its equipment list. 

It features the Honda Smartphone Voice Control System (HSVCs), allowing Bluetooth-based turn-by-turn navigation, call alerts, and music controls when paired with a communication device. A Type-C USB charging port is conveniently located for on-the-go device charging. The inclusion of Honda Selectable Torque Control (HSTC), or traction control, is a segment-first feature at its price point, adding a significant layer of electronic safety. These features are not mere novelties; they offer tangible, real-world benefits for daily commuting and occasional touring.

safety

Honda has equipped the CB300F with a robust safety package that surpasses many of its direct competitors. The primary safety net is the dual-channel Anti-lock Braking System (ABS), which prevents wheel lock-up during emergency braking on both the front and rear wheels. This system is crucial for Indian road conditions, where unpredictable obstacles and low-traction surfaces are common. The standout safety feature, however, is the Honda Selectable Torque Control (HSTC). This traction control system monitors front and rear wheel speeds and modulates engine torque to prevent the rear wheel from spinning under aggressive acceleration or on slippery surfaces like wet roads, gravel, or sand. 

This feature, typically found in more expensive motorcycles, provides a significant safety advantage. Furthermore, the all-LED lighting ensures superior visibility for the rider at night and makes the motorcycle more conspicuous to other road users during the day. A side-stand engine cut-off switch is also standard. This combination of active electronic aids and passive safety elements makes the CB300F one of the most securely equipped motorcycles in its class.

competition

The Honda CB300F enters a highly contested segment with several established players.

Suzuki Gixxer 250: 

This motorcycle is renowned for its supremely refined 249cc oil-cooled engine and a well-sorted chassis that offers a brilliant blend of ride and handling.
Differentiator: The Gixxer 250’s primary advantage is its exceptional engine refinement and perceived premium build quality, which feels a notch above its immediate rivals.

Bajaj Dominar 250:

Positioned as a sports tourer, the Dominar 250 uses a liquid-cooled DOHC engine derived from the KTM 250 Duke, tuned for touring.
Differentiator: Its significant heft, comfortable ergonomics, and stable highway manners make it a far superior choice for riders focused exclusively on long-distance touring.

KTM 250 Duke:

 The 250 Duke is the undisputed performance benchmark in this category, offering a high-revving liquid-cooled engine, premium WP suspension, and aggressive, razor-sharp handling.
Differentiator: It offers a significantly more engaging and thrilling riding experience, targeting the enthusiast who prioritises outright performance and handling dynamics above all else.

buying advice

Who should buy it?

The ideal buyer is a city-centric rider seeking a lightweight, easy-to-manage, and feature-rich motorcycle. Someone who values a strong safety package (traction control), modern tech (Bluetooth), and the future-readiness of flex-fuel technology over raw top-end performance would find the CB300F very appealing.

Who should skip it?

Performance enthusiasts seeking class-leading power and aggressive handling should look towards the KTM 250 Duke. Similarly, dedicated long-distance tourers who require better highway comfort, stability, and luggage-carrying capacity would be better served by the Bajaj Dominar 250.
