So many
attempted Laverda recoveries have ended in failure over the years that caution
is still required, but this time the famous old Italian firm really does seem
to be back on the right track. Latest owner Francesco Tognon has kept his
promise to invest heavily; the factory at Zan in north-eastern Italy is busy
and growing; and Laverda's team of engineers is working flat-out on a batch of
new bikes to take the firm into the 21st century.
The
revival that wealthy textile industrialist Tognon promised when he took over
three years ago is gathering momentum nicely. Later this year Laverda will
begin production of its sleek new 750 sports bike, powered by an enlarged,
redesigned and watercooled version of the faithful eight-valve parallel-twin
motor. And the firm's new-generation superbike, a powerful big-bore triple
intended to recapture the spirit of the legendary Jota 1000 of the 1970s, is
due to be revealed in prototype form at the Milan Show in November.
Both the
750 and the triple are intended to pass Californian noise regulations, with a
view to Laverda attacking the US market in the near future. In the meantime
the firm is already set to produce no fewer than three new models for other
markets, all based on the 668cc Ghost roadster. There's the limited-edition
Ghost Legend, with its orange-and-black paintwork and carbon-fibre parts; the
Diamante, a half-faired sportster; and the Ghost Strike, featuring bright
yellow paintwork, a neat twin-headlamp half-fairing and an aluminium twin-spar
frame in place of the standard Ghost's traditional steel ladder.
The Strike
is an interesting and neat-looking bike, but even so the obvious question has
to be: Why? What was the point of building another parallel twin roadster,
this time with an aluminium frame, when the Italian firm already had the
perfectly capable standard Ghost model with its steel trellis?
Laverda's
answer is simply that some riders prefer the style of a twin-beam frame. And
as they already had an ideal aluminium alternative used by the faired 668
sportster the Strike was cheap to produce. If you think of the Strike as an
easy way for Laverda to expand its range without diverting too many resources
from longer-term projects, the new bike makes plenty of sense.
Laverda
claims there's no difference in either weight or geometry between the Strike's
alloy beam frame and the steel trellis. Suspension is shared, too: 40mm
upside-down Paioli forks and a shock from the same Italian firm. The Strike's
engine is also unchanged: a 668cc DOHC, eight-valve parallel twin cooled by a
mixture of air and oil, and fed by a Weber-Marelli fuel-injection system.
The
Strike's wide, slightly raised clip-ons give a riding position midway between
sporty and upright. At 190kg the bike is pretty light, and at a standstill it
felt short and low. The seat is well-padded, although its shape means the
rider can't move about. At very low revs the engine was snatchy but it
smoothed out by the time 3000rpm came up on the white-faced tacho.
The
fuel-injection system (complete with a revised chip that is also fitted to the
standard Ghost) was excellent, giving a crisp midrange response that meant I
generally short-shifted instead of thrashing the Strike towards its 9100rpm
redline. At 90mph in top the Strike felt relaxed and reasonably smooth, with
acceleration in hand to a top speed of about 130mph. For a parallel twin the
Laverda ran well when revved higher, too. There's enough vibration to let you
know the motor's working hard, but in normal road use it's not a problem.
I was less
impressed by the test bike's Termignoni carbon-fibre cans, a factory optional
extra, which drowned out the engine's mechanical rustling with a thunderous
boom. The free-breathing pipes add a few horsepower to the standard peak
output of 70bhp at 8000rpm. But apart from being illegal in most markets
they're simply too loud for the road and besides, the Ghost's standard pipes
make a very pleasant twin-cylinder throb.
The
fairing did a good job of keeping the wind off my chest and didn't make the
bike weave at speed. But because I'm tall, the fairing's tip obscured my view
of the warning lights. Other niggles were the heavy clutch and a notchy
six-speed gearbox that made finding neutral a pain. The parallel-twin engine
unit has been extensively modified over the last few years, with recent
improvements including new piston rings, tougher valve seats and guides, plus
an uprated oil pump, but it can't help feeling a little crude at times.
There's
certainly nothing old-fashioned about the Strike's handling. Paioli's
suspension is excellent: firm but not harsh, giving a superbly taut and stable
ride. The Strike's steering isn't super-quick but the short, light bike's
neutral feel encourages you to throw it around in the corners.
Despite
the often slippery roads the Laverda's Pirelli Dragons gave plenty of grip,
too. And even repeated braking into downhill hairpins couldn't faze the Brembo
braking blend of 320mm discs and four-pot calipers. Plenty of bikes would
leave the Strike far behind on a straight road, but there are few that would
have the edge over it on the steep, switchback-strewn pass that leads over the
mountains near the Zan factory.
Even
Laverda admits that there's basically no difference in engine performance or
handling between the original Ghost model and the Strike, whose
standard-fitment fairing makes it slightly more expensive. Most riders will
probably opt for the cheaper and more traditional standard model, but the
Strike is good enough to justify its existence. It's a quick and enjoyable
roadster that will help keep Laverda's recovery on course while development of
that new-generation three-cylinder superbike continues.
