Let me begin thanking Rudi's Pantah Site for many of the
images collected on this page. Rudi's website is the best site I
have found documenting the Pantah hot rods and race bikes.
For me Pantah's express the abilities of Taglioni. His idea for
the Pantah engine was developed in the early 1970's and it took
almost a decade for the factory to approve its prototype. It would
be his last engine design and obviously his best, as today the
air cooled Ducati motor is still based from its design. Taglioni
and the Pantah were both part of a small passionate company,
barely surviving and being supported by the Italian government.
The last true Ducati before the company was sold in 1985 and
technology (851) and larger production (Paso) was put into the
Ducati belief to race winning motorcycles has been to build the
lightest chassis and most powerful engine possible. Weight to
Horse Power is the ratio that is an obvious method to compare
Weight HP P/W Ratio
750F1 370 60 6.16
750 Sport 390 60 6.5
TT2 300 76 3.95
TT1 300 85 3.53
Desmosedici 368 200 2.05
Porsche Turbo (stock) 3,600 450 8
Porsche Racecar 2,400 500 4.8
If you look at the Cadillac ... The 1990 750 Sport with the 944
motor (light wheels and Exhaust) weighs around 380lbs and
has 93HP (from dyno sheet) creating a 4.08 P/W ratio ... very
close to that of the TT2.
As wonderful as the Cadillac is, the passion I have for the F1
makes it a distant second. I have been thinking how to make a
reliable high horse power F1 ... Displacement.
Part of the challenge to this project is that Cagiva, the new
owner of Ducati was looking for effeciences and turned the rear
cylinder around on all engines beginning in 1989. This was so
carborators and fuel injection systems could be shared
between the cylinders .... The F1 was made until 1987 and
therefore never incorporated this new motor layout.
The 1990 750 Sport came with 6mm spacers on the right side
of the motor to align the chain on the left side and so the frame
could be used with the 900cc motor. This means the F1 frame
is 6mm too narrow (a 1/4") for a 900cc motor, so why not
machine the engine down to make it fit?
Swing arm from a 900 would need to be used, not sure if the
mounting point to the frame(s) are the same?
Intake system - The injection system since the rear cylinder is
turned around on the 900cc motor and both carbs sit in the "V"
and must fit below the tank. What is going to work here?
