Have an oppurtunity to purchase a barn find R100T.Guy says its an 1980 but dont know how many years this model was produced.I assume T is for touring which means its not as quick or sporty as the RS. Can anyone tell me something about this model?.I would li9ke to know specifically if it had the full fairing or the small round fairing that basically just covered the instruments.Thanks for any info .Jor4dan
