 | No
doubt that the 1000 Laverda is one of the bike which has the strongest character!
First comes its physical and aesthetical aspect, a very big and beautiful
engine, very clean design, and a general look which gives a very expressive bike
in spite of what is ultimately a very elegant picture.
The character
of the engine too, above all in 180° version, is made of a strong and brutal attitude!
Power and torque, deep sound, brutality, everything contributes to make a 1000
Laverda road test an unforgettable experience, even if we have tested so many
bikes before. No doubt that Laverda could have civilized this bike a bit, but
this is this wild character which finally makes of it a priceless experience.
There is no one-day 1000 Laverda tester: Until you ride it, you are doubtful,
even critical versus a monster that you can't really understand. But since you
test it, you just want it for ever! The 1000 Laverda has three cylinders
of 980,76 cm3, offering specs of a multicylinder (vivacity, high revs,...) and
in the same time also the strong character of a big unitary cubic capacity engine
(torque, deep sound, ...).
There were two crankshaft timings: The first
one, from 1973 to 1981, has two external pistons at TDC while central one is down,
hence the nick name of "180°". This timing was initially used to avoid excessive
side pressure onto the crank bearings, a well known problem on any 120° engine .
Thus the only engine ever built with a 180° timing was created, resulting
in a special character: Everything is different
compared to any marketed engine: The engine is brutal, the sound and feeling are
unique, vibes can be present... Add to that a...perfectible Bosch electronic ignition
(which did no favours for Laverda in its inquiries for the best products available
at that time...), accentuating the brutality of the beast, and you are riding
a sort of monster, all the pleasure laying to tame it... if you can... |
This
engine continues to delight the enthusiasts who still haven't found its equal
on the market. The 180° series includes the very early 1000s (with drum
brakes, quickly replaced by disc brakes), then in 1976 the 3CL which looked radically
different thanks to just a new seat and alloy wheels (The French and Swiss series
were unfortunately equipped with A12 camshafts, to comply the emissions and noise
reg.) and the Jota conceived under the requirements of the UK importer Slater's
(the 1000 Laverda was a best-seller in UK where it reached the status of a real
legend) which became the fastest bike on earth with the 1200 SC Laverda-Sulzbacher
built in Austria... The 1000 Laverda won the production bikes championship in
UK in 1976, 78 and 79 against others big japanese or british bikes, and also in
Austria, Sweden, Belgium... The
second engine series (1982 to 1989) got the same cubic capacity and an identical
design, but its crankshaft timing was 120° with the aim to civilize a bit the
Laverda triple. Result was a most manageable engine, without any power peaks,
closer to Japanese standards. In others words, the Laverda triple lost some of
its character but became easier for long trips and touring. At the same time,
it got a new bodywork design (conceived and built out of the factory by a design
studio) and changed its name, becoming the RGS. This bike was available also in
some others versions: Corsa (Sport), RGA (economic without the full fairing),
Executive (GT) and RGA Jota (with a different paint job and fairing). Finally,
in 1984, the SFC 1000 was produced (Corsa engine, different body work design)
which, paradoxically, rended some character to these last triples produced. Finally,
to get a excellent idea of the differences beetween the 180° and 120°
Laverda triples, here what said the Laverdist Ed Lutz, I couldn't find a better
and so right opinion:
"The two designs are
definitely different, and at times I find it easy to think they are completely
unrelated. The biggest difference to me is in the motors.
The 180 is a
torque monster, pulling from way down low with a hell for strong mid range that
pulls hard all the way up but seems to flatten off a bit on the high end. The
180 tends to vibrate a bit as it revs but unless one was weaned on Japanese fours
I don't think the vibes would be all that bad (if the bike is tuned properly.
If its not they can shake your hands off the bars!)
The 120 is much smoother,
almost no vibration at all as it revs up. The 120s power band starts off slow
but really likes to rev. The result is two bikes that feel very different, with
totally different personalities. Handling wise the 180s are taller, the 120s have
lower seats. To me the 120 is "softer" feeling, not as sharp, but thats probably
as much due to how I set mine up as anything else. I use my Executive for touring
and my Jota for sporting so have the suspensions set up differently. Too me
thats really the difference between the two designs.
The 120 is more refined,
smoother, makes me feel like knocking off the miles. I use that one for the 1000
mile days. The 180 is a hot rod, a bit of a beast, not refined at all and thus
that bike tends more toward shorter days going faster. I have toured on the Jota
though but would usually prefer the Executive for this. All that aside, if
one were to want to build a really fast Laverda I would think a 120 motor would
maybe be the way to go. The 120 in my Spondon special is a great performance motor
as it is smooth, it builds revs fast and doesn't take your attention away from
riding by vibrating or doing anything outside of its job. It also makes loads
of torque and horse power. You could build a 180 to do the same and probably make
just as much HP but in the end it might not work as well. Strange, but I think
it might be more fun as the 180 has loads more "soul" and to me at least sounds
much better but I don't think the end result would be as efficient, and performance
is really all about efficiency." And
these wonderful words by Tim Douglas ( http://members.iinet.net.au/~timdougl/bikes/laverda/wank.html
) , concerning the 1000 Laverda 180°:
"I
remembered what this Navy pilot said - after each landing on his aircraft carrier
(he flew those big piston engined AD-6 Skyraiders). When he finally parked and
turned off the ignition, the exhaust note would be gone and you could then hear
the big propeller go "Whop whop whop" as it spun down. And he'd have to stay in
the cockpit for a few minutes because his legs were shaking so much. Well, the
Laverda didn't quite have that effect on me, but I would still be sitting there,
looking at it, and these stupid words would keep going over and over in my mind:
"Holy hell, what an experience!"
On
her side, the 1200 Laverda is directly issued of the 1000, with a rebored engine
to 1116cc. The real initiator of the 1200 project was the Austrian importer
Werner Sulzbacher who got many excellent results since 1975 in production and
endurance championships with rebored triple engine to 1116 then 1172cc, winning
notably the Austrian championship in 1975 and 1976 with the engineer/builder/pilot
Franz Laimboeck. Right from the start, Sulzbacher put a pressure on the factory
to push it to produce a 1200 model, which finally arrived in 1978 with the 1200T
version. The 1200 was very close in appearance to the 1000 with just some
differences to the bodywork (tank, seat, side panels were different and a high
and large handle bar was fitted). The engine looked identical to the 1000cc, however
it was modified to cope with a tourism purpose, less sporty than the 1000. Bigger
80mm flat pistons were fitted and also a new crank and different carb needles,
the engine became more docile with an impressive torque at low and mid range,
the engine roar becoming yet deeper.
In 1979, in homage to the 30 years
of the motorcycle sector of the company, the factory produced a very special 1200
called "30 th", only 200 of them were built. Equipped with a fairing
and a black (included the engine cases) and gold paint job, it was sold to the
owners with a special original letter signed by Massimo Laverda himself. All the
200 models had been sold in a few days only.
The british importer Roger
Slater, who had a strong experience of race bikes with his Jota version, winner
many times of the UK production championship , decided to produce the 1200 MIrage,
sort of super-Jota equipped with most of the same endurance special parts like
the 4C cams, HS pistons on some of them, free-flow exhausts, and some times later
some very rare highly equipped versions like the Formula Mirage (special fairings,
Astralite wheels, etc...). In spite of their performance and equipment, these
models never reached the statuses of the Jota, many owners thinking that the Jota
was more homogeneous.
In 1981, taking advantage of the mods applied to
the 180 Jota (Ignition to the LHS, new 250W Nippon-Denso alternator, new Marzocchi
suspensions, ...), came the 1200 TS, proposed as a "Gran Turismo" bike,
with a new hi-quality bodywork more oriented toward long distance runs.
However,
1981 was the last production year for the 1200 models, the factory coming to produce
the new 120 1000cc engines. |
