“Yamaha just launched a motorcycle that can drink almost anything at the pump — and it’s not an electric bike.”
What is the Yamaha FZ Blue Flex and how much does it cost?
The Yamaha FZ Blue Flex is India’s first flex-fuel version of the popular FZ commuter motorcycle, launched at Rs 1,24,240 (ex-showroom, Delhi). Built on the FZ Rave platform, it runs on ethanol-blended fuels ranging from E20 to E85, making it just Rs 400 costlier than the regular FZ Rave while opening the door to India’s growing ethanol fuel infrastructure.

Why Yamaha launched a flex-fuel motorcycle now
India has been pushing ethanol blending in petrol as part of its cleaner-fuel roadmap, and several manufacturers have already responded with flex-fuel models. Yamaha’s Motor India Group Chairman, Hajime Aota, framed the launch as part of a broader strategy that treats electric vehicles and ethanol-compatible engines as complementary paths toward lower emissions, rather than betting everything on batteries alone. The FZ Blue Flex is Yamaha’s first flex-fuel motorcycle in India, arriving after the brand’s earlier push into electric mobility.
Yamaha isn’t alone here — Suzuki already sells the Gixxer SF 250 FFV, and Hero offers flex-fuel versions of the Splendor and HF Deluxe. What makes the FZ Blue Flex notable is that it’s being positioned as the first mass-market flex-fuel motorcycle in the 150cc segment specifically.
Engine, power and what changes with ethanol
The FZ Blue Flex uses the same basic 149cc air-cooled, fuel-injected single-cylinder motor found across the FZ range, but it has been re-engineered internally to tolerate higher ethanol content. That comes with a small performance trade-off: peak output drops by roughly 0.7 hp and 0.5 Nm compared to the standard FZ Rave, since ethanol carries less energy density than pure petrol. It’s still paired with the familiar 5-speed gearbox, telescopic front fork and rear monoshock suspension.
In real-world terms, this isn’t a performance-focused variant — it’s built for riders in regions where E85 or higher ethanol blends are becoming more accessible, and who want a bike that won’t need modification to use them.

Design and hardware: what’s carried over from the FZ Rave
Visually, there’s very little to separate the Blue Flex from the standard FZ Rave. It gets the same LED projector headlamp, sculpted fuel tank, single-piece seat and LED tail lamp. The 17-inch alloy wheels with tubeless tyres and the single-channel ABS setup are also unchanged. The two most notable hardware differences are a fuel tank that holds about 1 litre less than the FZ Rave’s, and reduced ground clearance of 135mm (versus 165mm on the standard FZ), largely a consequence of packaging changes for the flex-fuel system. Kerb weight is up slightly too, at 139 kg.
Buyers can also add LED turn indicators as an accessory at an extra cost, similar to other bikes in the FZ lineup.
Mileage: what to actually expect
This is the question most riders want answered, and honestly, it’s too early for a confirmed number. Ethanol-blended fuels typically return lower mileage than pure petrol because of their lower energy content, so expect the FZ Blue Flex to post different efficiency figures on E20 versus E85. Reviewers who’ve tested Yamaha’s related FZ models on regular petrol have recorded real-world city mileage in the mid-to-high 50s (kmpl), but Yamaha hasn’t published official ethanol-specific mileage numbers yet, and independent riding tests will be needed to know the real gap between blends.
Colours and variants
Yamaha is keeping this simple at launch — the FZ Blue Flex comes in just one shade, Metallic Black, with no other colour or trim options announced so far.
Where to buy and how to book
The FZ Blue Flex isn’t going pan-India just yet. It will initially be retailed through select Blue Square dealerships in Delhi, Uttar Pradesh, Maharashtra, Karnataka, Telangana and Tamil Nadu. Interested buyers can reserve a unit through Yamaha’s official website with a token booking amount of Rs 2,000.
How it compares to rivals
The FZ Blue Flex enters a small but growing flex-fuel motorcycle segment in India. Suzuki’s Gixxer SF 250 FFV was among the first to arrive, and Hero has flex-fuel versions of its budget commuters, the Splendor and HF Deluxe. Yamaha’s approach — bringing flex-fuel tech to a mid-segment 150cc commuter rather than either a budget bike or a performance-focused one — is what sets the FZ Blue Flex apart in terms of positioning.
Frequently Asked Questions: Top 25 Questions People Ask About the Yamaha FZ Blue Flex Launch
1. What is the Yamaha FZ Blue Flex?
It’s a flex-fuel version of Yamaha’s FZ motorcycle, built on the FZ Rave platform, engineered to run on ethanol-blended fuels from E20 to E85 instead of only regular petrol.
2. What is the price of the Yamaha FZ Blue Flex in India?
It’s priced at Rs 1,24,240, ex-showroom Delhi — only about Rs 400 more than the standard FZ Rave.
3. What does “Blue Flex” actually mean?
“Blue” ties into Yamaha’s Blue Square dealership branding and sustainability messaging, while “Flex” refers to flex-fuel — the engine’s ability to run on varying ratios of ethanol-blended fuel rather than a fixed blend.
4. What fuels can the FZ Blue Flex run on?
Anything from E20 (20% ethanol) up to E85 (85% ethanol), giving riders flexibility depending on what’s available at their local pump.
5. Is the FZ Blue Flex the same bike as the FZ Rave?
Mechanically and visually, it’s nearly identical — same frame, suspension, brakes and styling. The core difference is the ethanol-tolerant engine internals and fuel system.
6. What is the engine capacity?
149cc, single-cylinder, air-cooled, fuel-injected — the same base engine used across the FZ range.
7. What is the power and torque output?
Around 11.5–11.7 hp at 7,250 rpm and 12.8 Nm of torque at 6,000 rpm (reports vary slightly on the exact bhp figure).
8. Why does it make less power than the regular FZ?
Ethanol has lower energy density than petrol, so engines tuned for higher ethanol blends typically sacrifice a small amount of peak power and torque — a known trade-off across flex-fuel vehicles, not unique to Yamaha.
9. What mileage does the FZ Blue Flex give?
Yamaha hasn’t published an official ethanol-specific mileage figure yet. Expect lower efficiency on higher ethanol blends like E85 compared to E20, though exact numbers will need independent testing.
10. What colour options are available?
Only one at launch — Metallic Black.
11. What is the ground clearance?
135mm, which is 30mm less than the 165mm offered on other FZ variants.
12. What is the kerb weight of the FZ Blue Flex?
139 kg, about 3 kg heavier than the FZ Rave.
13. Does the FZ Blue Flex have ABS?
Yes, it comes with front and rear disc brakes paired with single-channel ABS.
14. What is the fuel tank capacity?
Around 12 litres, roughly 1 litre less than the FZ Rave’s tank.
15. Which cities or states is it available in first?
Initially Delhi, Uttar Pradesh, Maharashtra, Karnataka, Telangana and Tamil Nadu, through select Blue Square dealerships.
16. Where can I book the Yamaha FZ Blue Flex?
Bookings are open on Yamaha’s official India website.
17. How much is the booking amount?
A token payment of Rs 2,000.
18. What other flex-fuel motorcycles are sold in India?
Suzuki’s Gixxer SF 250 FFV, and Hero’s flex-fuel versions of the Splendor and HF Deluxe are already on sale.
19. Why is Yamaha launching a flex-fuel bike now?
It aligns with India’s government-backed ethanol blending push and gives Yamaha a second alternative-fuel strategy alongside its existing electric vehicle plans.
20. Is E85 fuel widely available at Indian petrol pumps?
Not yet on a large scale. India has been scaling up ethanol blending nationally, but higher blends like E85 are still limited to select regions and pilot rollouts, so availability will vary by city for now.
21. Can I run the FZ Blue Flex on normal petrol?
Yes — flex-fuel engines are designed to run across a range, from E20 up to E85, so regular ethanol-blended petrol (which is already E20 in much of India) works fine.
22. What is the actual difference between E20 and E85?
The number refers to the percentage of ethanol blended into the fuel — E20 is 20% ethanol, E85 is 85% ethanol. Higher ethanol content generally means lower fuel efficiency but can support India’s push toward alternative, less petroleum-dependent fuel.
23. What is the warranty on the Yamaha FZ Blue Flex?
Launch reports haven’t detailed a separate warranty specifically for the Blue Flex; it’s expected to follow Yamaha’s standard FZ warranty terms, but riders should confirm exact coverage with their nearest Blue Square dealership.
24. Will Yamaha bring flex-fuel tech to other models in India?
Nothing has been officially confirmed beyond the FZ Blue Flex, but given Yamaha’s stated multi-pathway strategy toward cleaner mobility, further flex-fuel models aren’t out of the question.
25. Is the FZ Blue Flex a good buy over the regular FZ?
It depends on your access to ethanol-blended fuel and how much you value future-proofing. For a small price premium of roughly Rs 400, you gain fuel flexibility, but you trade a little peak power and ground clearance — worth it mainly for riders in regions where higher ethanol blends are becoming common.
