Road Test
Moto Guzzi and Sport were two words that didn't
interlock in the minds of most enthusiasts until 1971. Then the Guzzi Sport
became available, and from that point forward Moto Guzzi meant something more
than just big, trucky, rugged, comfortable touring bikes.
The 750 Moto Guzzi Sport is not a motorcycle
along the lines of the Ducati Sport; it's much more civil. It has a comfortable
riding position, backed up by a cushy seat. The saddle does not have the
heraldic plushness of the old Eldorado's perch, but in the Café-racer class the
Guzzi Sport saddle has more uninterrupted miles in it than any other, save the
BMW R90S. The Guzzi clip-ons are far more adjustable than the normal stubs which
clench the fork legs of many Café-racers. The bars can be lowered to a point of
real discomfort, or raised to a level which allows a bolt-upright riding
position.
Your body will not be stretched out over a long
breadloaf gas tank. The Guzzi's fairly compact, stylish tank holds five gallons
(though you might guess less), and the short tank provides room for a dual seat.
So that 'makes the Guzzi Sport the socially friendly Café racer.
Moto Guzzi intended that people would actually
ride the machine over some distances, and as such the whole motorcycle says
"grand touring" in the original meaning of the phrase, to wit: a vehicle capable
to carrying an individual (or individuals) over long distances and difficult
roads in comfort, speed and style. Small and light baggage only, thank you.

While the Ducati 750 Sport or Desmo 750 Super
Sport are intended for high-intensity, short-duration bursts of motorcycling,
the Guzzi excels at long exposure. The Ducatis handle better than the Guzzi, and
are, by considerable margins, quicker and faster motorcycles. Ducatis are
motorcycles which immediately possess the sporting motorcyclist. Ride the
Bologna twins for 30 minutes and you can be absolutely hooked. The Guzzi drug is
slower-acting: it comes in time-release form.
Short acquaintance with the Guzzi Sport could
leave some enthusiasts a little cold. Sure, it's nicely finished, it has
electric starting, first-class lighting, shaft-drive, and impressive new double
discs in front. Indeed the monster discs are almost a foot in diameter, and the
double pie-plates broadcast a "mean machine" image. Nevertheless, the motorcycle
on first riding is frankly a little disappointing. There is a noticeable
sideways quaking from the 90-degree pushrod engine. loud honking through the
air-cleaner-less intake system, an aggravating shift pattern, sluggish
performance (compared to other sports bikes), insufficient cornering clearance,
and a front brake which lacks a pleasantly progressive feel.

Perhaps Moto Guzzi wanted to minimize the risk of
some customer overbraking in a panic situation. For the Guzzi system requires a
lot of hand pressure at the end of the lever's travel to squeal the front tire.
Not much happens in the first part of the handlever's arc; then at the end, the
progression is very clearly related to muscle-power in your hand. And so the
brake leaves the rider with the impression that the motorcycle stops well (which
it does) thanks to two average discs rather than one very good disc.
The vibration diminishes after 3500 rpm comes up
on the tachometer, but the vibration did linger beyond the 3500-rpm mark with
the double-disc Guzzi, though the machine did smooth out a bit as the odometer
clicked off the miles. Last year, a staff-owned Moto Guzzi Sport proved to be
silky-smooth at 3500 rpm from the very start. The differences between the
machines must be chalked up to production-line variances, something that happens
at every factory.
Those who liked the right-side shift on the 1973
Guzzi Sport may not warm up to 1974's left-side shift. That intricate assortment
of rods, bellcranks and tiny heim-joints which controlled the shifting from the
right side has been replaced with a simpler and cruder system which has more
slop in it than the old right-side mechanism. The brake, now on the right,
operates the twin-cam rear drum via a rod, as opposed to the older left-side
arrangement in which the connector was a cable.
It takes adjustment time on the Guzzi since the
shift pattern (up for first, then down) is exactly opposite all Japanese
machines. The pattern is unique to Moto Guzzi in the import field, and the
sequence is confusing. The Sport doesn't clunk badly gear to" gear, but you'll
be discouraged from running the motorcycle out to 7300 rpm and hammering a fast
shift through to second. That technique will produce a sharp little twitch to
the right. The torque reaction is not sufficient to change the direction of the
motorcycle, but the rider certainly can feel the reaction in the saddle. Riding
the machine normally, and rolling the throttle hack and slowing the shift, will
eliminate the twitch.
