swingarm direct bolt on for the klx frame-doubt it
relocate the shock mount-probably
rear wheel direct bolt on-yes, with the right spacing. you can use kx60 wheels on a stock 110 so i'm sure the opposite will work, the kx60 wheels are better though
if you look around this site you will see that just about anything is possible and with some cutting/welding you might be able to make all of it work, don't know if it's worth the trouble
i have never seen anyone use the kx60 swingarm setup, lots of people have done the kx65 conversion and plenty of people use kx65 brake's on their aftermarket swingers with siktendencies adapter kit
if you want to see a good one about the kx65 swingarm conversion on the klx search art5's threads
