I started an 85 CR125 project last year. After I tore it down I found a broken frame, swing arm, radiator etc. I was about to have the frame welded back up and replace the swing are but recently I found an 85 cr250 bike without a motor for sale locally. Will my 125 fit using the 250 motor mount tabs on that frame? Will I have fitment issues between frames? If I have to rework some stuff if there any advantage to the 250 suspension or other parts? Did the 85 CR250 come with a rear drum brake or a disc? The pic with the bike online looks to have a drum just like my 125. Sorry for all the questions I'm
excited
