In a completely different sector of the market
to its two-stroke stablemate is the Benelli 250/4 which is, as its name
suggests, a four-cylinder bike of approximately 250CC. Like the larger
six-cylinder 750 Sei, the 250/4 is an undeniably extravagant bike and that is
something which is reflected in its astronomical price, a figure which is almost
twice that asked for the CE Benelli. It is not in performance where the
four-stroke four has an advantage for, with 26.5bhp and a top speed of just on
90mph, the CE gives nothing away at all. What is interesting is that the
four-cylinder 250 is almost 5olb lighter than the CE and in every dimension is a
very small bike indeed.
The heart of the bike is an overhead-camshaft
engine which looks something like a miniature 500 Honda unit and is, in fact, of
basically the same design. Maximum power is produced at io,5oorpm but the engine
is safe to over 11,000 where it makes a sound like a noisy sewing machine. If
the engine is not revved to its full potential, the fuel economy is excellent
and far better than anything possible with an engine of two-stroke design.
Apart from the engine, most other parts of the bike are of conventional design
with a front disc, rear drum and standard oil fork dampers and swinging arm. The
designers have, however, made the small Benelli appear as modern as possible
with a one-piece tank/seat/rear fairing unit. Set in a panel in the front of the
tank unit is the instrument nacelle with a tachometer and speedometer.
Unfortunately, however neat it looks, the dials are hard to see and take ones
attention away from the road.
To finish the modern appearance there are
cast-alloy three-spoke wheels which look a little odd but are strong and easy to
clean. As with the CE, a Moto Guzzi version of this bike is available, called
the 254. Its styling is a little different but again is merely badge
engineering. The company did experiment with a bike powered by two of the
little 'fours' mounted together to make a 500 V8, but the costs were
prohibitive, while a 125CC 'four' developed at the same time as the 250 was
thought to be just too extravagant.
