Original 1991 PROSTAR Motorcycle Drag Racing EBC Brakes TOP FUEL CLASSIC and Rivera Engineering/Primo Belt Drives TOP FUEL HARLEY CLASH Series vinyl Contingency Stickers. The EBC sticker measures approximately 6" across x 5-1/4" high and the Rivera sticker measures 6-1/2" x 3". Almost impossible to find, these stickers were given out only to the participants in both series for placement on the race bike and were printed in very limited numbers. These are 100% original period stickers obtained when I was the Prostar Series announcer. Near Mint/Mint and Unused. True condition can be seen in the photos. From my personal collection. I combine or discount shipping on multiple purchases when possible. Any questions please ask. Thanks for looking!
