Yamaha's 2013 version of its YS250 Fazer for the Brazilian market that runs on gasoline, ethanol fuel, or a  mixture of both. The new YS 250 Fazer BlueFlex is Yamaha’s first flex-fuel model,

Brazil is the world’s second largest ethanol fuel producer and the most successful biofuel-based economy. About 90% of all new cars sold in Brazil use ethanol but flex fuel motorcycles are relatively new.

According to Yamaha, the BlueFlex model weighs 339.5 pounds, just 2.2 pounds heavier than the original YS250 Fazer, which Yamaha introduced in 2009. Both versions are equipped with 249cc single-cylinder engines with five speed transmissions, 5 gallon fuel tanks, telescopic forks and a rear monoshock with 120mm of travel, front and rear disc brakes and 17-inch wheels.
