WHY WE BUILD
A MOTORCYCLE WITH A
4O-YEAR-OLD ENGINE.
In 1970, Yamaha introduced its first
four-stroke vertical twin—the XS-1.
And it was better than any motorcycle
of this type had ever been before.
The British had long used this
engine design because of its steadfest-
ness, reliability and willingness to
perform. Unfortunately, it suffered from
the shakes as its two big pistons slapped
joyously up and down.
But today’s 1978 XS650, with its
sophisticated overhead cam, represents
the ultimate refinement of this grand old
mill. After eight years of continual
improvement, that nerve-numbing
vibration has become merely a blurred
memory.
Crankshaft counterweighting, spe-
cial engine mounting and a lot of late
nights in the Yamaha engineering labs
have made the XS650 one of the
smoothest, most reliable and versa-
tile street machines you can buy.
All the modern-day niceties
are included. Tailing-caliper front
disc brake for better handling and
surer stops. Electric starter. Adjust-
able five-position shocks. Everything
you need to get from here to there with
comfort and confidence.
And, as you can see, all the styling
tradition of those wonderful days gone
by is still there, too.
The 1978 Yamaha XS650. Some
things get better with age.
1 • This 650cc, SOHC twin pumps out
more power than ever before thanks to a
higher 8.5:1 compression ratio.
I'Counterweighted. crankshaft balancing
minimizes vibration in this classically
narrow fourstroke twin.
3'Roller-bearingcrank and cam shafts
make for smoother performance and
greater durability.
^•Matched 38mm constant-velocity
carburetors feed regularfuel to valves
with special alloy seats. Powerband is
exceptionally broad and usable.
5. Special double-duplex cradle frame
is reinforced at high-stress areas
and designed with precision geometry
relationships.
6. Close-ratio, five-speed transmission
ivith short-throw lever for fast, positive
shifting in any situation.
