I think an R80RT of that era would have been monolever from new so it has not been converted, the spoked rear wheel will not fit as it has three bolts and the monolever one has four. Apart from the insruments there is not much ST about this bike, it still has twin silencers and the right hand silencer mount is not there on the ST frame which is which another difference.
This does not mean it is not a capable machine, a friend of mine has done the same to his monolver RT and loves the bike but if you want an ST you will have to buy one as this is nothing like it.
From what I can recall the only parts that are the same are the engine and gearbox, just about everything else is different.
If it's in the Touratech catalogue then you don't need it
