Yamaha XV750
It seems only yesterday
that the American-style cruiser trend
hit Europe, but in reality Yamaha paved
the way for this category as early as
1981 when they first unveiled a cult classic
that became the defining bike of this
class: the XV750 Virago.
Mounting a specially developed
75-degree V-twin engine on a pressed backbone
type frame with Monocross rear suspension,
the XV750 Virago was a pure American style
cruiser in every aspect. From the planning
stage of the development project, customer
surveys were conducted in the U.S. And,
when those surveys revealed that users
considered the 'V' engine to be the power
unit of choice for cruisers, the project
would remain true to that preference.
The fact that Yamaha's engineers made
the development of the company's first
side-positioned V-twin power unit the
centerpiece of this project is further
proof of their desire to make this model
the real thing.
At the same time they were
fully aware that there would be no meaning
in building a bike that was merely a duplication
of American makers like Harley Davidson.
The aim was to fully grasp the tastes
of the American riders and then create
a bike with a distinctively Yamaha character
and attention to detail. Only that kind
of attitude could produce a cruiser that
was the real thing.
The appeal of the V-twin
engines of American-style cruisers was
the kind of hard-biting torque that bites
into the road and an exhaust sound with
powerful pulse. On the other hand, Yamaha's
strengths lay in the high level of its
race-bred engine performance, an obsession
with form and the beauty of the lines
of the cooling fins. So the development
objective became a well-balanced marriage
of these two contrasting engine characters.
The most difficult decision was the "V"
angle. After analyzing the full range
of different angled V-engines from Harley,
Ducati, Vincent, Moto Morini from the
standpoint of pulse strength, quality
of performance, effect on chassis design
and the beauty of the V itself, the Yamaha
team decided on the 75-degree V.
Then, in order to build
a chassis with the impressive low and
long styling of the traditional cruiser
with a typically Yamaha light weight and
slim lines, a new monocoque structure
steel pressed backbone type frame was
developed. This frame, which used the
engine as a stressed member, was designed
to embrace the engine with all its front-rear,
top-bottom protrusions of the head assembly
in a way that showed off the beauty of
the air-cooled 75-degree V-twin as much
as possible.
At the same time, numerous
innovative measures were taken to make
optimum use of the limited space around
the engine, such as using the space inside
the frame as an air passage to supply
air to the carburetors positioned in the
V-bank so that the air cleaner box could
be positioned under the seat. All this
enabled a design with a low seat height
of just 750 mm and slim body lines.
Furthermore, taking into
consideration the preference of American
riders for sturdy, durable design and
the convenience of maintenance-free components,
a Yamaha-exclusive shaft drive system
was adopted. And, to ensure comfortable,
enjoyable riding, our latest Monocross
rear suspension was adopted and equipped
with a remote-control 6-level adjustable
air cushion set.
The resulting model was
a true flagship for Yamaha as a maker,
aggressively pioneering new possibilities
in the American cruiser category.
