Don't wanna be picky, but the tag on the steering head lists month and year of manufacture. My ol' SSMST was sold as a 91 but shows 2/90 so she's officially 25+ years old a real classic.
And, she's over 223,000 miles so 200,000 of those are mine, mine mine.
Add those to the 140,000 I've added to lipSTick and the 130,000 I put on STanley (nee ReSTored) and I've got at least 470,000 miles on STs. Wish it were more.
