I am having yamaha fzs 2015 model. yamaha is good company having long lasting durable engine.ride of this bike is very smooth and full of comfort but the average is little annoying it gives me an average of only 28 to 30 kmpl which is bad. m using it on highway for my college updown.engine is buttery smooth in 70 to 85 kmph but above it bike feel some struggle. I got a top speed of 121 kmph. which is good but bike struggle and the sound of engine changes when we drive continuos in above 100 kmph and the average also goes to 25 kmph worst part of yamaha is average.
