Go to www.morini.de; this is the German Morini web site and they have a lot of information on the various Morini models - including torque and power curves.
The factory Moto Morini web site also has a section on the engine, but it is far more arty and less use these days... The Sport is as nice (if not nicer) to ride, and puts out less power with a lower fuel consumption.
shacard, you can draw your own torque curve from the power curve you have, just read off the graph the ps and engine speed at as many points as you like and then plot your torque curve using the formula:
Torque (Nm) =power (kW) x 60000 \ (2 x pi x engine speed (rpm) )
You can convert from ps to kW by multiplying ps by 0.74
Hope that helps but all you really need to know is the corsaro has buckets of torque
