I like the FZ09 better. I am 155lbs and 5-7", i do find the suspension a tidy bit soft but after i set it to stiffer setting, it rides alright. for style and uniqueness the XB12S is more outstanding for sure, but I really hate the vibration and the occasional hiccups from the engine. So overall, and the FZ has~20ft/lb less torque, but it revs up so quickly, with 11000 rpm and 10hp advantage i think the FZ is faster. and i guess Yamaha is more reliable. so if you're ok with the look of the bike, maybe a good idea to switch over. i also tried FZ07, Monster 1098, street triple and streetfighter. if i don't have to worry about maintenance i'd pick streetfighter 848.
