On the eve of the appointment of
Cooper Motors, Los Angeles,
California, as U.S.A, distributors for
AJS and Matchless motorcycles, the
A.M.C. firm in London, England, an-
nounces their 1956 models.
The new range of AJS and Match-
less motorcycles is certainly enhanced
by the addition of a brand new mod-
el ; the 600cc “Super Clubman”. This
model, which incorporates all of the
proven features of the former range
of twins, is in effect, a “big brother”
to the well known 500cc twins.
Another point of interest, is the
fact that rigid frames have disap-
peared completely from both lines,
and even the trials mode) is equipped
with the well engineered, and popular
swing-arm rear suspension.
The frames themselves have been
redesigned, the principal difference
being the seat post, which is now ver-
tical. It has attached to it, at the
lower end, a lug which provides the
pivot bearing for the swing-fork. This
lug is extended downward to bolt be-
tween the rear of the engine cradle
members.
A general cleaning up of all models
is evident. The spindle clamps, for
instance, incorporated in the top
bridge piece, now neatly anchors the
control cables.
Worthy of note, is the rather strong
oil pump which on the twin cylinder
models, pumps at the rale of 26 gal-
lons per hour. The side of the tank
is protected by a shield which provides
an air space between it and the reser-
voir. The reason for this is simply to
protect the pillion passenger from
discomfort caused by extremely hot
oil, which is circulated at a terrific
rate. Details, such as this one, have
been given the closest scrutinization
on all AJS and Matchless models for
1956.
The new competition model Scram-
bler, is fitted with a much improved
single cylinder 500cc ohv engine. The
flywheels of this engine are steel forg-
ings, and the big end bearing is of
the 7r racing type. An all new con-
necting rod of robust proportions, is
incorporated. Also, in addition to the
normal method of supporting the
crankshafts, an additional large roller
bearing is provided on the timing side.
The pushrod tubes are incorporated in
the cylinder casting. Even with the
large bore of the cylinder, the finning
provided, is exceptionally generous.
The new 500cc engine has a bore
of 86 mm and a stroke of 85 mm. This
cversquare designs is reported to de-
velop approximately 39 B.H.P.
For the American market, both the
Clubman Twins, and the Sport Twins
will be equipped with the new 600cc
engines. Also, the popular Sport
Twins, with alloy fenders, 21 inch
front wheel, and 3 gallon chrome
sports tank; will be available.
So with the introduction of the
600cc twins, A.M.C. makes a strong
bid for acceptance by those who de-
sire the spirited performance of large
capacity rtwins, coupled with superb
handling qualities and moderate
weight.
