back in 75,74 green backs were painted red to look like current models & now in these vmx days red backs are painted green to look like 74s,its gone full circle!
It was a common mod back in the day to move the shock mounts forward,luckily for you & me only our swingarms were modded & easily returned to stock,frames however were a different matter & were often cut & shut big time,frame rails moved,shock mounts removed alltogether & new ones added,seats & pipes cut up etc,some of the jobs were pretty damn rugged too,I also have a cr250m it had the upper shock mounts moved forwards,luckily they left the original mounts in place & didnt cut the frame at all,it was a simple matter of just cutting off the dodgy mounts & back to stock
