Yamaha launches flex-fuel FZ at Rs 1.24 lakh

Yamaha has launched the FZ Blue Flex – a flex-fuel-compatible version of the FZ that can run on ethanol blends ranging from E20 to E85. The launch makes Yamaha the latest manufacturer to enter the flex-fuel space, following Suzuki with the Gixxer SF 250 FFV and Hero with the Splendor and HF Deluxe.

1. First Yamaha model to be offered in a flex-fuel variant
2. Uses the same engine as the rest of the FZ range, but with lower peak output figures
3. Available through Yamaha Blue Square dealerships

Yamaha FZ Blue Flex details

Peak output drops compared to the standard FZ; ground clearance is also lower

The FZ Blue Flex is powered by the same 149cc air-cooled, fuel-injected single-cylinder engine that underpins the rest of the FZ range, but with modifications that allow it to run on higher ethanol blends. Peak output is rated at 11.7hp at 7,250rpm and 12.8Nm at 6,000rpm – a drop of 0.7hp and 0.5Nm compared to the standard FZ. This is a common trade-off with flex-fuel engines due to ethanol's lower energy density.

The FZ has never been the most powerful motorcycle in the 150cc segment, and the Blue Flex's lower output brings it close to the performance levels of some premium sporty 125cc commuters.

The FZ Blue Flex shares its LED headlamp with the FZ Rave launched late last year, along with the same fuel tank, faux air vents and single-piece seat. The 5-speed gearbox, telescopic front fork, rear monoshock and single-channel ABS have also been carried over. One notable change, however, is the reduced ground clearance, which drops to 135mm from the 165mm offered by the other FZ variants. Kerb weight stands at 139kg, making it 3kg heavier than the FZ Rave.

The FZ Blue Flex is available in a single Metallic Black colour option and will initially be sold through Yamaha's Blue Square premium dealerships in Delhi, Uttar Pradesh, Maharashtra, Karnataka, Telangana and Tamil Nadu. Priced at Rs 1.24 lakh (ex-showroom), it sits roughly in the middle of the nine-model FZ lineup.

We recently conducted a comprehensive real-world mileage comparison between E85 and E20 using the Suzuki Gixxer SF 250 FFV. If you're curious about what switching to flex fuel means for fuel efficiency and running costs, it's well worth a read.
