RT and RS models replaced by the naked R100R, which ain’t quite classical and heavy compared to the old 70’s Boxers, though the gearbox and handling have evolved out of all recognition. RT/RS remain useful high speed tourers, though the RS has the better fairing and superior appearance. Both have reasonable longevity, though occasionally ruined by inconsiderate DR’s. R100GS’s hot when equipped with Paralever rear suspension but often thrashed.
