Hero MotoCorp has done it again. The company known for building bikes that run forever and sip fuel like a miser has now launched something that feels like a perfect fit for today’s India—the Hero HF Deluxe Flex Fuel. If you’re someone who rides every day and is tired of watching petrol prices climb higher every month, this new bike could be a game changer for your wallet.
So, what exactly is a flex fuel bike? How does it work? Is it any different from your regular HF Deluxe? Let’s break it all down in a way that’s easy to understand and totally real.
What Is Flex Fuel?
First, let’s talk basics. A flex fuel engine is one that can run on more than one type of fuel. In the case of the Hero HF Deluxe Flex Fuel, it can run on both petrol and ethanol-blended fuel (up to E85).
What’s E85? It’s a fuel mix that contains 85% ethanol and 15% petrol. Ethanol is usually made from sugarcane or corn, which means it’s renewable. Petrol, as we all know, is fossil fuel. So, running on ethanol helps reduce pollution, supports farmers, and cuts down India’s fuel imports.
Pretty cool, right?
Looks Familiar, Feels New
At first glance, you might not even realize it’s the flex fuel version. The design is still very much the HF Deluxe we’ve all seen and trusted over the years. But Hero has added a few small touches to help it stand out.
You’ll see a dual-tone color scheme with green and yellow graphics that represent its eco-friendly nature. The branding clearly shows “Flex Fuel,” so people know it’s running something special.
The build quality is solid. It still has the same lightweight yet strong frame, alloy wheels, and that compact design that makes it perfect for city rides and small-town streets.
Engine & Fuel Flexibility
Now let’s get to the heart of the bike—the engine.
The HF Deluxe Flex Fuel comes with a 97.2cc single-cylinder, air-cooled engine, similar to the regular petrol version. What’s special here is that this engine is tuned to work smoothly on a wide range of ethanol blends—from E20 (20% ethanol) to E85 (85% ethanol).
The power output is slightly tweaked to suit the ethanol blend, but you still get a smooth ride, quick throttle response, and excellent pickup for a bike in this category.
This engine is BS6 Phase 2 compliant, which means it meets the latest emission norms. You get cleaner fuel combustion and lower emissions overall—another win for the planet.
Fuel Efficiency That Makes Sense
Let’s be real—most people buy the HF Deluxe for one reason: mileage.
The flex fuel version continues that tradition, but with a twist. When running on ethanol-rich fuel, you may notice slightly lower mileage compared to petrol because ethanol has less energy per litre. But here’s the good part—ethanol is cheaper than petrol.
So even if the mileage dips a little, your cost per kilometre goes down. That’s what really matters for daily riders.
Hero hasn’t given an exact mileage number yet, but based on real-world reports and tests, expect around:
- 65–70 km/l on petrol
- 60–65 km/l on E85 fuel
And if you fill it with something in between, like E20 or E50, you’ll land somewhere in the middle.
Smooth Riding Experience
The HF Deluxe Flex Fuel doesn’t try to reinvent the wheel when it comes to riding feel. That’s a good thing.
The suspension setup—with telescopic forks up front and dual shock absorbers at the rear—keeps the ride comfortable. Whether you’re dodging potholes in the city or cruising on a rural road, it handles bumps well.
The seat height is low enough for most riders, and the handlebar positioning gives you an upright, relaxed posture. You can ride this bike for hours without feeling tired.
Start-Stop Tech
One thing that adds extra value is the i3S (Idle Start-Stop System). This tech automatically shuts off the engine when you’re idling in traffic and turns it back on the moment you pull the clutch.
The result? Less fuel wasted while waiting at traffic signals. It’s a small thing, but when you ride daily, these small things add up fast.
Built for the Everyday Indian
This bike is clearly made for the common man. Hero understands its audience—office goers, college students, delivery riders, and folks who want a no-nonsense bike that works every day, doesn’t break down, and doesn’t burn through cash.
Here are a few everyday perks:
- Low maintenance costs
- Easy availability of parts
- Wide service network across India
- Fuel tank capacity of around 9.1 litres
- Lightweight body for better handling
It’s also kick-start and self-start compatible, so you’ve got convenience whether you’re new to biking or a pro.
The Green Angle
One of the biggest reasons behind the flex fuel push is environmental.
Ethanol burns cleaner than petrol. It produces fewer carbon emissions, less smoke, and lower carbon monoxide output. This makes it a better option for the environment.
Also, India grows a lot of sugarcane. Using ethanol made from sugarcane juice or molasses supports local farmers. So every time you fill up on E85, you’re helping reduce pollution and supporting the Indian economy. That’s a win-win.
Price & Variants
Hero hasn’t gone wild with pricing. The HF Deluxe Flex Fuel is priced only a bit higher than the standard petrol version. That’s a big relief because new tech often means higher prices, but Hero has kept it very approachable.
Expected price range: ₹60,000 to ₹65,000 (ex-showroom)
Considering the dual-fuel flexibility, low running cost, and Hero’s trusted name, this is a great deal.
Should You Consider It?
Absolutely, if:
- You ride daily and want to cut fuel bills
- You care about the environment and want to reduce your carbon footprint
- You need a reliable, affordable, and low-maintenance bike
- You want the freedom to choose between petrol and ethanol based on availability and price
Final Thoughts
The Hero HF Deluxe Flex Fuel isn’t just another bike launch. It’s a smart move toward future-ready commuting. It blends what we already love about the HF Deluxe—simplicity, efficiency, and comfort—with the added benefit of cleaner fuel and flexibility.
Hero has taken a bold step, and if this works well, we might see more brands follow the same path. But for now, Hero leads the way with a bike that’s practical, eco-friendly, and still very much rooted in Indian roads.
If you’ve been waiting for a bike that respects your budget and the planet, the HF Deluxe Flex Fuel might just be your best ride yet.
