thats it in a nutshell basically.
84 had gold colored forks, rims, swinger. drum brakes up front, the clutch springs, pushrod, and plates were different, 8" 4x4" botl pattern rims. rear shock wasnt as adjustable.
85 was upgraded to disc front brakes, silver forks, swinger, rims. different clutch springs, push rod, and plates, 10" rims with the 4x156mm bolt pattern, and a better more adjustable rear shock. the fork springs and valving were beefed up i guess you could say as well. i believe the dogbone on the 85 is different in length as well then the 84 model.

Life's journey is not to arrive at the grave safely in a well preserved body, but rather to skid in sideways, totally worn out, shouting "HOLY SH-T, what a ride!"
