Yamaha has launched the FZ Blue Flex in India, its first flex-fuel motorcycle, priced at Rs 1.24 lakh (ex-showroom, Delhi) and built to run on ethanol blends from E20 to E85. The bike joins Suzuki's Gixxer SF 250 FFV and Hero's flex-fuel Splendor+ and HF Deluxe as manufacturers respond to the government's ethanol-blending push, giving buyers a commuter option designed around fuel flexibility rather than performance. It uses the FZ's familiar 149cc engine, retuned for higher ethanol tolerance, and is sold initially through select dealerships in six states. Here is what changes on the bike, and what it means for day-to-day ownership.
What's Different?
The Yamaha FZ Blue Flex carries over the regular FZ's 149cc air-cooled, fuel-injected single-cylinder engine but
with internal changes that let it run on ethanol blends up to E85. That comes at a cost: peak output drops to roughly 11.5-11.7hp and 12.8Nm, down from the standard FZ's 12.4hp and 13.3Nm since ethanol carries less energy per litre than pure petrol.
Ground clearance is also reduced, from 165mm on other FZ variants to 135mm. Styling carries over largely unchanged with the same LED headlamp, sculpted tank, single-piece seat and 17-inch alloy wheels and the bike is offered in a single Metallic Black shade.
What Buyers Should Know
The FZ Blue Flex is not a pan-India launch yet. Yamaha is selling it only through its Blue Square dealerships in Delhi, Uttar Pradesh, Maharashtra, Karnataka, Telangana and Tamil Nadu, so buyers outside these states will need to wait or arrange delivery through a dealer in one of them. Bookings are open on Yamaha's website against a Rs 2,000 token amount. Front and rear disc brakes come with ABS as standard and the bike retains the FZ's 5-speed gearbox and telescopic front fork.
Why Power Drop Matters
The lower output is the trade-off buyers take on for ethanol compatibility and it brings the Blue Flex's performance closer to some 125cc commuters rather than the rest of the 150cc FZ range. For someone using the bike mainly in city traffic, this is unlikely to be noticeable day to day but riders who value outright acceleration or highway overtaking margins should weigh this against the fuel-cost benefit before choosing the Blue Flex over a standard FZ variant.
