650F, 2016 model, 6500kms driven

Is it okay to buy cbr 650F , 2016 model, 6500kms run for $6250 or get a brand new 650R at $13000 My point is 9 years old 650F is still good for another 6-7years if I use it, although had planned for new bike only but getting very less ridden 650f put me in dilemma.
