hi ihad something like that in my mind about the swingarm because i wanted to put an ohlins shock but i gave up because the summer was near and i didnt have the time,so as for the tire this is the best way to put the 160,the 150x60x17 it can be fit on the swingarm without these cuts,you can use spoke rim 4.50'x17or 18 if you want but the 4.50'is the wider you can fit because of the oppening of the swingarm from the one side to the gear side about the way the distance from the one side to the other is about 120mm i think so if you want to put a 150 or 160 tire you have put it in with out air at all.As for the hub of the rim you can use the hub from gl gooldwing that it has spoke rims,that for now and you have also to find out how and where to put a bracket on the frame for the shock.Here some other ways to put a monoshock on
