Hey guys hoping to get some owners advice. Currently upgrading to a low hour 450 as I'm getting over seat bouncing my 85kgs round the local track (mt kembla) on a 250f. Is the 14+ bike a large improvement over the 10-13? I ride my mates 11 a bit and quite like it although if the newer bikes have a more nimble feel then I'm sure I would enjoy it more. Understand the motor and suspension will be very similar, but wonder if all the other changes make for a better ride. Thanks in advance.
