Have you ever wondered what a Vespa engine born in the 1950s would look like
produced with 2020 technology? Pinasco can finally give you the
response you were expecting with the new crankcase dedicated to the world of
"grandmothers". Die casting molding technology,
steel sliding, closing of the engine casing with studs,
new gearbox axle bearings, increased crankshaft + 7mm of
width compared to the original, lamellar suction (optional),
predisposition for 4-speed gearbox, high speed main bearings,
operation with 2% mixture.

All without changing the aesthetics of the engine, the external walls have NOT been sandblasted to maintain the color and raw style of the historic
they have been positioned in hidden areas and with the characters of the time, to have a modern product but as similar as possible to the original.

The new Pinasco Wide Frame Engine Cover allows you to use Vespas
Old exactly like the more modern ones with high performance ed
reliability.

Mount VL3T or higher components.

The V-One has been designed for those who want a perfectly replaceable crankcase with the original, supplied with all the components necessary for assembly and which allows maximum interchangeability with the components on the market, does not require any aesthetic modification of the vehicle and adapts to all original Piaggio parts

The main seats are designed to accept the original bearings and crank oil seals (not supplied). V-One can be fitted with the original Dell'Orto Si 24-24 carburettor
It is possible to use the original crankshaft or our 57mm stroke rotary valve crankshaft art. 5316082. Whatever the choice, the power supply has still been revised and implemented thanks to our moderns
CAD systems that have profiled an inlet duct in the optimized crankcase.

The new reinforced wheel axle for smallframe vespa engines is
made of very high strength steel and relative treatment of
vacuum cementation.

The material used and the new sizing make the tree
particularly suitable for engines prepared or with larger displacements
to the norm (even up to 250 ccm)

Today, thanks to recent investments by some manufacturers, it is
You can find on the market a very large selection of thermal groups
powerful that even exceed 40 horsepower.

I remind you that the smallframe vespa engine was born to last in
time and that its power hardly exceeded 10 horsepower.

With these increases in power, it is essential to adapt all the kinematics in order to avoid premature breakage and wear.

Example of the new dimensioning. The thread has also been increased to M16x1.25
