Moto Guzzi is one of the most legendary motorcycles brands out there and the V8 is one of the
best and motorcycles of all time.
With its complex 8 cylinder 500cc engine the Moto Guzzi V8 could reach speeds that other
GP motorcycles would reach only after 10 years.
Despite being way faster and powerful than other motorcycles the V8 failed to achieve
success.
Hello guys and welcome back to another video and this is The Story Of Moto Guzzi V8 - Two Wheel Madness.
Moto Guzzi was known for making great single and twin cylinder motorcycles for racing a
for road use.
But after they lost the 1954 Grand Prix championship against Gilera they decide to build a new
revolutionary bike.
They knew that 4 cylinders weren't powerful enough and a 6 cylinder would be to wide so
the solution was a V8 500cc motorcycle.
The V8 was designed by the lead engineer Giulio Carcano, assisted by Umberto Todero and Enrico
Cantoni and was build in just 5 months after they got the approval from Moto Guzzi principals
Carlo Guzzi and Giorgio Parodi.
The idea behind the Otto (Eight how the V8 is known in Italy) was to build a revolutionary
motorcycle which could reach new speeds.
The idea indeed was with high risks because the V8 was only used by cars at the time and
was complex and expensive to build.
The new motorcycle was tested for the first time in 1955, both the engine and the bike
were without precedent: a water-cooled, 500 cc (31 cu in) V-8 motorcycle — with dual
overhead cams and a separate carburetor for each of the eight cylinders.
In fact the Moto Guzzi engineers having been accustomed to air-cooled engines, actually
forgot to engage the water pump on the water cooling system on the V8 the first time they
tested the motorcycle.
The Otto Cilindri was fairly lightweight, weighting at only 148 kg/326 lbs and with
a power output of 75hp at 12000 rpm the V8 could reach a top speed 275 kmh/170 mph, a
pretty impressive top speed for the time.
The V8 engine was a piece of art on its own.
The engine weight only 45kg/99 lbs, the tiny cylinders, with dimensions of 44 mm/ 1.7 in.
bore and 41 mm/ 1.6 in.
stroke were arranged in two banks at 900 to each other a gear train drove the double overhead
camshafts.
Eight carburetors, 20 mm. bore, were tucked in between the banks.
Tyre, brake and suspension technology, however, lagged behind the powerful engine—making
race course field testing difficult and actual racing dangerous.
Only Dickie Dale, Stanley Woods, Alano Montanari, Keith Campbell, Bill Lomas, Fergus Anderson,
Giuseppe Colnago and Ken Kavanagh were ever able to even ride the V8 motorcycle.
Several of the riders experienced spectacular falls—Bill Lomas suffering a head injury
at the 1956 Senigallia Grand Prix.
Fergus Anderson crashed the motorcycle on its maiden run in Modena.
Ken Kavanagh refused to ride the motorcycle after the 1956 race at Spa-Francorchamps.
The Otto Cilindri also proved complex and expensive to build and maintain because bikes
suffered broken crankshafts, overheating, and seizing, all in addition to the danger
the bike posed to the racers themselves.
By 1957 there were two bikes available and no one willing to race the bike without further
development.
Instead, the Otto remained undeveloped, as Moto Guzzi and other manufacturers withdrew
from racing entirely in the 1957 season.
