125-200cc Any differences between a 2008 and 2012 CR125?

I recently picked up a low hour 2008 Husky CR125. I also own a 2012 Husky CR125.
Are there any differences (mechanical) between them? They look alike to me.
Thanks, your knowledge and help is appreciated.

Motors are the same except the cylinders maybe the ignitions also thats all I can think of at the moment.I have an07 for sale at the moment.

Thanks, I wasn't sure what was different. FMF did not list a pipe/silencer for a 08

The frame changed in 2009 resulting in different bodywork, different shock, different rear wheel (for the offset), different seat, and probably a few other affected items. The engine remained the same.
