Hello, Am interested in purchasing the ninja 650RL. Tossing up between that and GSX650FU.. There is not much on the net about the 650RL.. Does anyone have one or know of anyone that does?? I want to know how these machines go.. I want to keep the bike for 3 years + so i dont want anything that's going to COMPLETELY bore me.. that's why I am leaning away from the 250r. Is it that much quicker (got more power) than the 250 version? I'm 6 foot.. too big for this bike maybe? Can the seat height be adjusted? I heard that it is hugely underpowered, making it have the same (if not very similar) acceleration to it's 250r brother, is this correct? If anyone would be kind enough to complete a review of this bike i would be much appreciative.
