India has been pushing ethanol-blended fuels for a while now, and bike makers are finally launching products to match. The Suzuki Gixxer SF 250 Flex Fuel was unveiled at the Bharat Mobility Global Expo in January 2025, alongside the Honda CB300F Flex Fuel, the only two bikes in India at the time that could run on E85 fuel. Hero MotoCorp has since followed with flex-fuel versions of the Splendor+ and HF Deluxe, and it is safe to say more will come in future.
The Suzuki Gixxer SF 250 Flex Fuel is built for riders who already appreciate what the standard Gixxer SF 250 offers: a smooth quarter-litre engine, comfortable ergonomics, and reliable everyday performance, but want to be ahead of the curve on fuel technology. It targets the 250cc sports segment, sitting comfortably against bikes like the Yamaha R15 V4 and KTM RC 200, while also bringing an environmental argument that neither of those bikes can make.
Suzuki Gixxer SF 250 Flex Fuel Price in India
The Suzuki Gixxer SF 250 Flex Fuel is available at Rs 2,16,500 ex-showroom in Delhi. Depending on the city, ex-showroom pricing may vary slightly. The on-road price in Delhi works out to approximately Rs 2,50,500, which includes RTO and insurance charges.
The flex fuel variant commands a premium of Rs 9,500 over the standard Gixxer SF 250, which is priced at Rs 2,07,000 ex-showroom in Delhi. That is a relatively modest ask for the added fuel-compatibility technology underneath.
The bike is available through Suzuki’s authorised dealership network across India. Availability in smaller cities may need to be confirmed with your local dealer.
Suzuki Gixxer SF 250 Flex Fuel Variants
The Suzuki Gixxer SF 250 Flex Fuel is offered in a single variant only; there is no trim hierarchy to navigate here. It comes in two colour schemes: Metallic Mat Black No. 2 / Metallic Mat Bordeaux Red and Metallic Mat Black No. 2. Both options carry the same matte finish that the standard Gixxer SF 250 is known for, with Flex Fuel and E85 compliance badging added to distinguish this version.
Engine & Performance
The Gixxer SF 250 Flex Fuel is powered by a 250cc single-cylinder, liquid-cooled engine producing 27.9PS on E85 fuel and 27.2PS on E20 fuel, with 22.5Nm of torque across both fuel types, paired to a 6-speed gearbox.
In day-to-day use, the engine feels well-suited to Indian riding conditions. It is smooth in city traffic, pulls cleanly from low revs, and does not demand constant gear changes. On the highway, it settles into a comfortable cruise around 90-110 kmph without feeling strained. There are some vibrations noticeable at the footpegs and handlebars at higher speeds, which is fairly typical for a single-cylinder motor in this displacement class.
The six-speed gearbox shifts cleanly, and the power delivery is progressive rather than aggressive, which makes this a motorcycle that inspires confidence in new riders while still being satisfying for more experienced ones. The slight bump in power on E85 fuel is worth noting: you get marginally more from the engine when running on higher ethanol blends, though the difference is not dramatic enough to feel on normal roads.
Flex Fuel Technology
Flex fuel, in simple terms, means the motorcycle can run on varying blends of petrol and ethanol, anywhere from E20 (the standard fuel currently available across India, which contains 20% ethanol) all the way up to E85 (85% ethanol, 15% petrol).
To make this work, Suzuki had to make meaningful changes to the fuel system. The adaptation required notable enhancements to the bike’s fuel injector, fuel pump, and fuel filter to handle the corrosive properties of high-ethanol blends and the different combustion characteristics of ethanol compared to petrol.
The Indian government recently introduced E85 fuel at Rs 82.12 per litre in Delhi, which is around Rs 20 lower than E20 petrol. As E85 availability grows across more fuel stations in India over the coming years, the Gixxer SF 250 Flex Fuel is well-positioned to benefit. Ethanol is largely domestically produced from sugarcane and agricultural waste, which also means lower dependence on imported crude oil, a long-term advantage both for riders and the country.
Mileage & Fuel Efficiency
The ARAI claimed mileage of the Suzuki Gixxer SF 250 Flex Fuel is 33 kmpl. Real-world numbers, as always, differ.
In real-world conditions, the Suzuki Gixxer SF 250 Flex Fuel is expected to return around 34-38 kmpl on E20 petrol, depending on riding style, traffic conditions and road usage.
On E85, the story changes. E85 returns approximately 24.4% lower fuel economy than E20, based on real-world instrumented testing. This is because ethanol has a lower energy content per litre than petrol. E20 offers around 30.5 MJ/litre, while E85 drops to about 23.5–24 MJ/litre.
So while E85 is cheaper at the pump right now, the drop in efficiency partially offsets the price advantage. Running cost on E85 may work out to be marginally better or roughly similar to E20, depending on the fuel price difference in your city. It’s worth checking your local E85 price before making a decision. With a 12-litre tank, you can expect a real-world range of around 400-415 km on E20.
Design & Comfort
The Suzuki Gixxer SF 250 Flex Fuel looks identical to the standard model. It carries the same fully-faired styling, which still looks sporty and proportionate, though the design has now been around for over six years without major updates, and it is beginning to show its age compared to newer rivals that look sharper.
It features a sharp LED headlight, large body panels, a split seat, a transparent visor, and a short exhaust with a chrome heat shield and tip. Build quality is solid, with well-finished panels and paint that feels premium for the price point.
The riding posture is a mild crouch, not as aggressive as a full sportbike, but more committed than a naked. It works well for both city and highway use. The seat is reasonably cushioned, and most riders should find longer rides comfortable enough. Pillion accommodation is adequate for short trips, though the split seat design is not the most generous setup for two-up riding over long distances.
Features & Technology
The Gixxer SF 250 Flex Fuel gets an LCD that can be connected to a smartphone via Bluetooth and supports turn-by-turn navigation along with call and SMS notifications. Additional connectivity features include WhatsApp alerts, over-speed alerts, ETA display, battery and mobile network status, digital wallet alerts, and periodic service reminders.
The instrument cluster displays gear position, speedometer, trip meters, fuel gauge, and odometer. The display is easy to read and shows essential information clearly, though it does not offer a colour TFT screen, which some rivals in a similar price bracket have begun offering.
Lighting is fully LED front and rear, which improves nighttime visibility and gives the bike a modern look, even if the overall design is getting long in the tooth.
Safety Features
The Gixxer SF 250 Flex Fuel gets disc brakes at both ends and dual-channel ABS, with 17-inch wheels all around. The front disc measures 300mm and the rear 220mm.
Braking performance is adequate for the segment. The lever feel is positive, but the initial bite from the front brake could be stronger, and there is room for better brake progression.
The front telescopic and rear monoshock suspension has a firm feel but manages rough city roads without serious trouble. The ride stays composed over undulations and expansion joints; sharper potholes and rumblers will be felt, but there is no harsh kickback from the rear. Handling is stable and predictable, though not particularly sharp or exciting. It will suit riders who want a bike they can trust rather than one that constantly demands attention.
Summary
The Suzuki Gixxer SF 250 Flex Fuel makes a solid case for itself as a forward-thinking buy in the 250cc segment. The engine is smooth, refined, and now slightly more capable on E85 fuel. The Rs 9,500 premium over the standard model is easy to justify if you are planning to hold onto the bike for a few years. As E85 fuel becomes more widely available, the running cost advantage will only improve. For someone who commutes regularly and also uses the bike on weekends, this is a genuinely practical proposition.
Where the bike falls short is in design freshness and feature depth. The styling has not seen meaningful updates in several years, and rivals like the Yamaha R15 V4 or KTM RC 200 feel more contemporary when you look at them. The instrument cluster, while functional and Bluetooth-connected, lacks the colour display or the visual flair that some buyers in this price bracket now expect. Brakes, too, could offer a more confident initial bite.
That said, the Suzuki Gixxer SF 250 Flex Fuel is not trying to be the most exciting motorcycle on paper. It is built to be dependable, future-ready, and easy to live with, and on all three counts, it delivers. If you value engine refinement, fuel flexibility, and everyday usability over outright performance numbers or cutting-edge design, this is one of the more sensible choices available in its class right now.
