So, still some question, then: what is a 2002 "Sport?"
Has handlebars (not "clip-ons)? Headlight and instruments mounted to the frame (not the forks?) There are braces coming forward of the side plates to the lower rear of the engine? More smooth semi-gloss (or fuzzy, bubbly flat) black engine paint)?
That would all make for a second generation frame and the 5.5" rear rim with a more "relaxed" steering geometry. Any of the good sport-touring tyres will serve well. Again, a lighter, quicker feel with the 170.
