Unfortunately I bent the subframe on my 2010 CRF450R again; I got away with bending it back straight the first time I did this but this recent time it broke the top cross member whilst attempting to straighten it. Given the 2011 CRF450R received modifications to the subframe to strengthen it (09/10 models have a notoriously soft subframe), does anyone know if I’d be able to bolt on an original 2011 model subframe to my 2010 model bike? As the plastics are all the same, I’m hoping it would bolt on as a straight replacement and I'd benefit from the changes. Alternatively if anyone has suggestions for aftermarket manufacturers (apart from AC racing who I’ve contacted but haven't yet received a response from) who make subframes for the CRF 450R? Thanks in advance!
