I am using the yamaha fz for more than 2 yrs . its a very good bike. self balanced , better safety, stylish, offers comfort rides, I went a tour on this bike a total of 1000km , I did not have any back pain. butyou have to adjust the tappet every 15000km or once im a year or else in cold areas the bike gives worse fuel efficiency and power , sometimes the engine would not even start
