NEWCOMER to the BSA range for 1962 is this all-new
Royal Star Twin, available in both 500cc and 650cc execu-
tions. Engine and transmission are housed in a common unit.
Simplicity and cleanliness arc further enhanced with under
saddle nacelle, which encloses toolbox, carburetor, air clean-
er, battery and oil tank.
TOP INTEREST in the 1962 BSA
motorcycle range centers in the en-
tirely new “Royal Star” 650cc and
500cc twins, but there are other new
models, and many improvements in the
entire line. Many models feature bril-
liant new metallic finishes, and again,
BSA offers an unusually liberal array
of bright chrome in all machines.
Royal Star Twins
Entirely new in design are these
newcomers to the BSA range, the A65
650cc and the A50 500cc twins. Built
on entirely new frames, these large
capacity twins have new tanks, new
fenders, new enclosed carburetor—oil
tank—toolbox nacelle, and a host of
other entirely new features of which
the most important is the new en-
gine-gearbox unit, one clean, stream-
lined unit which includes engine,
gearbox, primary drive and clutch.
Engine cases are highly polished alumi-
num and there are no unsightly pro-
trusions, no external oil lines. Hand-
some and rugged in appearance, these
power units should be easy to clean
for bright and sparkling appearance.
Experience gained in many years of
manufacture of large capacity motor-
cycles is built into these new power
units. Cylinder barrels are heavy-base
type, and cylinder heads are aluminum
alloy with cast-in valve seats and down-
draught inlet ports. Exhaust ports are
widely spaced, and cylinder heads are
amply finned for good cooling.
BSA’s own big forge shop produces
the manganese-molybdenum forgings
for the Royal Star crankshafts. With
oversize bearings thruout, and full
pressure lubrication, these new BSA
power units provide smooth and ample
power for top performance in any
speed range. A good power-to-weight
ratio and lower overall weight also
assists in achieving sparkling perform-
ance in these new BSA Twins.
The 650 unit is slightly oversquare
with bore of 75mm and stroke of
74mm. The bore and stroke of the
500 are 65.5 x 74.
Finish of the new twins is unusually
striking, with the 650 in brilliant
metallic red, and the 500 in bright
metallic blue. Both models are striking-
ly set off by large chrome tank panels,
chrome exhaust system and mufflers,
chrome handlebars, wheel rims, and
many other parts in bright chrome.
Super Rocket
Still very much at the top-of-the-BSA-
line is the famous Super Rocket. The
BSA factory has developed a new
siamesed cross-over exhaust system
and new glass pack muffler, making
for improved cylinder scavenging, ac-
hieving a significant boost in horse-
power. On Eastern U.S.A. Super
Rockets the exhaust system is optional
if available at time of order, otherwise
the handsome twin pipes and twin
mufflers are fitted. The new exhaust
is standard on Western U.S.A, models.
The new Rocket also has the BSA
full-race camshaft, “Big Valve” cylindei'
head, and 9-1 pistons for full power
output. Improved self-energizing brakes
are fitted to this model. Finish will be
new metallic red tank with chrome
panels, chrome fenders, black frame.
Many other parts are finished in
chrome or polished alloy on this model.
New Sport 350
New for 1962 is the model SS-90
Sportsman designed for 90 mph speeds.
This is a sports edition of the 1340 in-
troduced in the 1961 season, and offers...
