1975 HARLEY-DAVIDSON MX-250:
COMING OR GOING?
Harley-Davidson’s entree into motocross was a byproduct of the marriage of Harley, Aermacchi and AFM. When parent company AFM
asked Harley to enter the growing motocross market,
Aermacchi was a reliable source of two-stroke engines.
At the 1974 Omaha 250 National, Sonny DeFeo debuted
the first Harley-Davidson MX-250. Only 65 of these bikes
would ever leave the Milwaukee factory.

The 242cc Aermacchi-built engine was housed in a
chromoly Champion frame. It is best remembered for
having forks on both ends.
The MX-250 used Showa forks and Kayaba fork-style
rear shocks. The front hub was from a Yamaha, while the
rear wheel housed an Airheart disc brake powered by an
H&H caliper. Other components included K&N handlebars,
Oury grips, Magura controls, Sun rims and Buchanan
