Ossa Phantom 250  1974


Within a few years Ossa sales were booming with a reputation for building quality
machines, known for handling and reliability. By the late 1960’s despite a somewhat spotty
dealership and parts network, Ossa was making a name for itself in the United States, with
bikes like the Pioneer, Super Pioneer and Stiletto. Ossa had a motorcycle for every type of
off-road racing, from observed trials, to short track. The 1974 Ossa phantom was perhaps
the best motocrosser Ossa ever produced, and was able to compete with the super fast
Japanese mx bikes of the time. The Yankee-Z 500cc twin scrambler and street bikes were
produced by Ossa, and are considered collector items since only about 500 were built,
close to the end of manufacture for Ossa.

I had a 1972 Pioneer that was one of the most reliable motorcycles I ever owned. The only
real annoyance was the carburetor, a Spanish made IRZ that had dual everything inside of
it, dual slide needles, springs, dual main jets, pilot jets, etc. When the carb was apart, it
could fill a small bucket with all the stuff that came out of it. Putting it back together was not
something you did after drinking a few beers, as slide needles, springs and clips would
shoot all over the garage, and disappear. I guess it beat using an Amal, but not by much.

Ossa not only produced some great off-road machines, but road racing bikes as well. In
1974 a monocoque rotary valved 250 road racer designed by the founder’s son Giro
Herrera, won four Grand Prix races at the hands of factory rider Santiago Herrero. Sadly,
Herrero was killed in the 1970 Isle of Mann Grand Prix, and Ossa withdrew from road
racing completely, to concentrate on its domination of observed trials (that some
considered a Spanish national sport). Mick Andrews captured the observed trials
championships of 1971 and 1972 riding Ossa.

Ironically, the motorcycle boom that created such a demand for European off-road
motorcycles also led to their demise. Ossa had to invest heavily in new manufacturing
facilities to combat the Japanese onslaught, that ultimately left them and other European
motorcycle manufacturers deep in red ink. Heavy debt, an unsustainable parts/dealer
network and a crippling employee strike in 1977 led Ossa to merge with Bultaco in 1979.

By 1982 both Bultaco and Ossa were out of business. Montessa was next, and it was all
over for the Spanish off-road motorcycle.

The OSSA Remember the Ossa, that
oddball Spanish motorcycle with the
four-leaf clover insignia? Started from
humble beginnings as a manufacturer
of movie projectors, in 1949 Ossa
began producing motorcycles based
on the design of a pre-war DKW 125.
It seems every major motorcycle
company from Harley Davidson to
BSA to Yamaha copied the same
125cc two stroke DKW, down to the
last bolt. The founder of Ossa, Manuel
Giro was a Spanish sidecar champion
on a BMW, and together with his
copilot (monkey) Francisco Bulto
(Founder of Bultaco) the pair racked
up wins all across Europe in off-road
sidecar competition. Those Spanish
motorcycle titans were a tight knit
bunch it seems.
