As someone that purchased there first HD back in 1979, Harley is a pin I really wanted to like/own. The first HD pin was the 1991 Bally. I have never seen or played this pin. The Sega/Stern Harley of 1999/2000 was produced during a period of astronomical HD motorcycle demand. Weak design & even weaker gameplay didn't seem to matter as long as the pin incorporated the HD sound, had the HD images & references to Sturgis. The 2003 3Rd edition is a reskin of the earlier version, brought to market for Harley's 100th anniversary.
Over time, the Harley pin demand is driven by wealthy HD motorcycle owners, seeking yet another HD accessory. I would guess the pin does pretty good on route.

As a Harley owner & somewhat serious pinhead, I see the Harley pins as a disappointment. They could have done so much with the theme, and did so little.
