|Casings: The casings are very similar to 150 Sprints.
Cranks: The crank is the same as a later Sprint, and all P
series 125 and 150cc bikes which are readily available.
Standard Barrel: The standard
barrel has three crankcase transfers. The barrel is not really useful
for tuning as there are many aftermarket big bore kits that are better.
Kits: Any 3 port large frame
kit over for up to 150cc original bikes.
Ignition: These bikes have 12V points systems but the crank is the correct taper for a P200 electronic flywheel. The flywheel, stator and CDI will need to be used.
Gearbox: Most later large
frame gearboxes after the Vespa 150 Sprint will fit. The clutch can be
upgraded to a "Cosa" clutch for better performance.
