WHAT THEY COST
Only available at select Harley dealers and priced at
$1375, the 65 examples of the MX-250 are very rare.
This near-perfect example is valued at $15,000.
WHAT TO LOOK FOR
Parts for the engine can still be found (from the
supply of SX-250 trail bike engines). What is
unobtainable is the Champion frame, with its
square-tube swingarm and Kayaba (labeled as Red
Wing by Harley) rear fork/shocks. In addition, the
Showa forks with cast triple clamps and the Hurst/
Airheart disc rear brake are scarce.

spokes. The Aermacchi engine actually made good
power when mated to a 36mm Mikuni carb (although
some engines came from Italy with Dellorto carbs). The
expansion chamber was silenced by a pickle-style muffler,
which would break or fall off with regularity.
What was the bike like to ride? It wasn’t fast, but it
had good low-to-mid that required short-shifting. Most
test riders claimed that the fork-like rear suspension was
surprisingly good and that the Showa forks were very good.
Some MX-250 racers replaced the rear disc brake with a
Yamaha hub with a drum brake instead. There was no
motocross success, but Bruce Ogilvie won the 1975 Baja 500
on one. Production was halted in 1975, but Harley would try
again with a new bike in 1978. The new MX-250s were raced
by Marty Tripes, Rich Eierstedt and Rex Staten. Harley’s moto-
cross effort ended in 1979 and was never started up again.
