just to give my 2cents. i am 178, weight 86. and i rode krr for 2 yrs. what bike you want, is actually depend on you. sports bike like krr and sp is nice, good to corner but as it is ard 10yrs bike, so u must be prepare some money aside for maintainance.
phamton although in my view look abit uncle, but i would recommend tat bike. low maintanance fees, no need 2t and quite cheap nows day.
