I am gonna buy the HOBBYWING Ezrun Max10 ESC with 3652SL (5400Kv) Motor Combo for my Fazer. It comes with brushless motor and ESC. You will also need some PINIONS for higher speeds. With this motor, 3s and a 33t pinion I already get up to 59mph. You can get faster speeds if you add a 34t, 35t, 36t or 37t pinion.
