QUATTRINI M3XC GTR EXPANSION for Vespa Smallframe

This expansion was created and designed to get the best out of the M1 and M1L cylinders of the Quattrini house, but it is also excellent for other cylinders with comparable timing and displacements. To improve the flow of exhaust gases, it has been designed to go around the rear shock absorber of the Vespa, thus having a much smoother curve than the classic expansions for smallframe.

For mounting on ET3 and Primavera requires the elimination of the drawer.

If mounted on a piaggio casing it requires the removal of a part of the air cooling conveyor nut in the upper part of the flywheel side casing.

Delivered complete with silencer and the necessary for assembly. unpainted.
