The Gixxer SF 250 FFV features a 249cc, single-cylinder, four-stroke engine. To handle ethanol-blended petrol ranging from E20 to E85, it adopts an updated fuel injector, fuel pump, and fuel filter capable of withstanding higher ethanol content.

In terms of performance, the engine produces 27.2 PS on E20 and rises slightly to 27.9 PS on E85 (both at 9,300 rpm), alongside 22.5 Nm of peak torque at 7,500 rpm. It also achieves a claimed top speed of roughly 150 kmph. The power is managed via a 6-speed manual gearbox, paired with Suzuki’s Easy Start System for one-touch ignition without holding the clutch.

Lastly, fuel efficiency under ARAI testing sits between 33 and 35 kmpl on E20 petrol, yielding a practical range of nearly 400 km from the 12-litre tank.

The Gixxer SF 250 FFV retains the standard model's sharp, GSX-R-inspired fairing and sporty matte finish, distinguished visually by subtle FFV badging. At the front, an LED headlamp sits below a windscreen, while low-set clip-on handlebars mounted on 41mm telescopic forks offer a committed, forward-leaning riding position.

Tucked behind the screen is the digital console, displaying speed, gear position, fuel level, and smartphone notifications. The silhouette flows into a split seat with a passenger grab rail. Ensuring a planted ride, the bike features 17-inch alloy wheels fitted with a 110/70 front and 150/60 rear tyre, supported by a preload-adjustable rear monoshock. The tail section is completed by a compact LED tail lamp, a functional tyre hugger, and a signature twin-outlet muffler.

The Gixxer SF 250 FFV comes with dual-channel ABS as standard, paired with disc brakes front and rear - the front disc measures 300mm in diameter. This prevents either wheel from locking up under hard braking.

The flex-fuel system also adds two warning indicators. A petrol concentration warning advises the rider to add petrol if a high ethanol content begins to affect performance, while a cold-temperature warning alerts riders when ethanol-rich fuel may cause starting or running issues in low temperatures.

A side-stand interlock cuts the ignition if the bike is started with the side stand down, and LED lighting front and rear helps with visibility for other road users.

In the fully-faired 250cc-class sportbike segment, the Gixxer SF 250 FFV closely competes against the Yamaha YZF R15 V4, the Bajaj Pulsar RS200, and the KTM RC 200. The YZF R15 V4 features a smaller 155cc engine but highlights traction control, a slipper clutch, and a lighter 141kg kerb weight. The Gixxer counters with its larger 249cc motor yielding higher torque (22.5 Nm vs. 14.2 Nm), a bigger 12-litre fuel tank, and E85 flex-fuel compatibility.

The Pulsar RS200 features a 199.5cc engine (24 PS/18.7 Nm), switchable ABS modes, and a 13-litre tank. The Gixxer counters with a more potent 249cc powertrain (up to 27.9 PS/22.5 Nm) while undercutting the RS200's 166kg kerb weight by 3kg.
 
The RC 200 pairs a 199.5cc DOHC engine with premium USD front forks, an adjustable monoshock, and a larger 13.7-litre tank. The Gixxer punches back with superior torque (22.5 Nm vs. 19.2 Nm), a more accessible 800mm seat height, and E85 flex-fuel capability absent on the KTM.

The Suzuki Gixxer SF 250 Flex Fuel is packed with a comprehensive suite of features designed to enhance the riding experience and provide modern convenience. One of the standout elements is the fully digital instrument cluster, which offers a wealth of information at a glance. It includes a speedometer, tachometer, gear position indicator, fuel gauge, and a clock. Additionally, the console features a specialized indicator for the Flex Fuel system, keeping the rider informed about the fuel status and system health. The display is backlit for high visibility in both bright sunlight and low light conditions, ensuring the rider stays focused on the road.

Lighting is another area where this motorcycle excels. It features a full LED setup, including the headlamp, position lights, and tail lamp. The LED headlamp is designed with a wide throw to illuminate the path effectively during night rides. For added convenience, the bike comes equipped with the Suzuki Easy Start System, which allows the engine to fire up with a single brief press of the starter button. This feature is particularly useful in stop and go city traffic. The inclusion of a side stand interlock adds a layer of safety by preventing the engine from starting or running when the stand is deployed.

The chassis and suspension components are also noteworthy. The bike uses a high tensile steel cradle frame that provides the necessary rigidity for sharp handling. Suspension duties are handled by telescopic forks at the front and a monoshock at the rear, which is adjustable for preload. This setup is tuned to offer a plush ride over bumps while remaining firm enough for confident cornering. The braking system consists of large disc brakes at both ends, providing strong and predictable stopping power. Furthermore, the bike features wide radial tires that offer excellent grip and stability, especially during high speed maneuvers. These features collectively make the Gixxer SF 250 Flex Fuel a well rounded package that caters to the needs of tech savvy riders.
