How about:
'Scotts Race Face' attached to the bottom of your goggles.
'Snuff-or-nots' (a street mostly option) consisted of a washer/spring/handle on it, fitted in the straight pipes of mostly mid sixties Honda 305's, to quiet the bike when 'in town' and open er up for the road.
Yamahas first 'Monoshock' with the rear shock that attached to the steering head, thru the gas tank. Made the gas tank 'appear' to hold about 10 gallons.
Malcolm Smith tool pouches for the rear fender, the ones with the 3 separate 1/4 turn fasteners.
'Whispering Smith' quiet 2-stroke exaust systems.
The pure magic sound of a big Kawasaki street bike, with 3 separate expansion chambers on it.
Denim riding pants.
Real leather riding pants in red white and blue (mine were size 28 waist, what the heck happened to me?).
Bates leather gloves.
