Vespmoto 244 - vmax 143 kmh
Quattrini 244 - very elastic and powerful - from 60 to 100 kmh in 4 sec in 3rd gear
Performance from lowest engine speed - with absolute stability
Now you can ride the Vespa in traffic like a motorcycle
The Quattrini M244 tests and adjustments have been completed!
As seen in the driving videos, the engine generates enormous power
from the very lowest engine speeds up to the highest.
The M244 reed valve engine can do both,
torque and power.
I am thrilled by this engine.
These videos should not animate to drive
but better than any Dyno they show the power and drivability of this engine.
Now you can move the Vespa like a motorcycle in traffic.
This engine is so powerful that Vespa cruising is really fun.
Can be driven in 4th gear from 50-60 km/h.
Tested exclusively with a box exhaust.
