can anyone please tell me the exact differences between the 85 and 86 atc swingarms? is it just the way the back brake is held on? i know the bearing carriers are different too i believe-any info you guys have would be great-thanks alot-

 

The only difference I can think of is the rear bearing carrier/bearings/bearing spacer are different.....BUT the mounting portions are the same, so if you want to throw the 86 arm on the 85 ( or vise-versa) you would use the carrier, bearings, and axle out of the bike that the swingarm came from.

 

The brake mount and sprocket are also different.
