1975 Harley Davidson / Aermacchi MX 250 Prototype

Here is a very cool and rare 1975 Harley Davidson / Aermacchi MX 250 Prototype. This submission is from E. Carlson of Wilmington, Delaware. Here is Mr. Carlson’s description of his bike:

You are looking at one Harley / Aermacchi 1975 MX-250 prototype motocross bike. This bike was hand build by Harley Davidson Racing engineers for Harley dealers only, and was not available for sale to the public. This Harley has front and rear air ride suspension a hydraulic rear brake system (this was unheard of in 1975 on an mx bike.) My family owned a Harley dealership from 1971 to 1992 and we bought one of these bikes to promote our dealership in the Delaware Enduro Race in 1976. After that year, the bike was on display on our showroom floor ever since.
