i didnt kno u was a member on there, well if u hadent notice the forum is shut down for right now and it kinda sucks

an r6 swinging is longer and a yzf is the same as a stock but wider to fit a 180 rear tire

putting in a yzf motor is a direct swap few things need to be changed butt it will work

it u plan on doing that swap let me kno so i can help u out on that

with that bike in mint shap u should get no more than 2500
maybe 300 if ur lucky

if i was u i keep it cuz it works well in the twisties and is awsome to ride
