Equipped with a self-locking cone capable of stably coupling the crankshaft and pinion.

With this system, the key does not need to be used. Ideal
for modified engines and for crankshafts damaged at the key seat.

The cone is compatible with the entire range of Piaggio crankshafts and interchangeable. It is recommended to apply strong type threadlocker on the
fixing nut and to respect the tightening torque of 60-70 Nm.

For disassembly, a 3-thread puller is required, not included.

The new CM5 is a top-of-the-range clutch that allows our
vespa/ape to function correctly with powers exceeding 30 hp
without needing to add spacers between the engine casing and the clutch casing.


It includes no. 5 guranite discs with the latest generation material (thickness 2.00mm) no. 4 hardened metal discs (thickness
1.20mm) no. 2 compression springs with increased load, full spider, circlip with anti-rotation notch, oil-taking pressure plate
with bearing, key + washer + high-strength nut. To reduce the considerable resistance of the springs on the clutch lever, it is
mandatory to use a clutch casing with rack and pinion reduction combined with a handlebar lever with a pivot-ball center distance
of at least 25.00mm.

Withstands 30hp

Includes no. 4 discs lined with latest generation material
(thickness 2.00mm) no. 3 hardened metal discs (thickness 1.20mm) no. 2
compression springs with increased load, full spider, circlip
with anti-rotation notch, oil-catching pressure plate with bearing,
key + washer + high-strength nut. To reduce the
considerable resistance of the springs on the clutch lever, it is mandatory
to use a clutch cover with rack and pinion reduction combined
with a handlebar lever with a minimum pivot-ball distance of 25.00mm.

Born for drag racing, it optimizes the clutch operation both in release and grip.


The 2 support planes for the springs ensure that the clutch plates descend performing the correct movement.
Completely reinforced at critical points, it is made from solid high-strength steel. Designed for central spring clutches/double central spring.
Compatible with original clutch and extractor.

The suction cap is made of stainless steel with a thickness of 1mm. It is manufactured through laser cutting and subsequent laser marking. Useful for protecting the luggage compartment from dirt when not in use. Included are no. 4 white zinc plated T.B.E.I M6x6 screws with locking coating.

Born for the soft use of the Vespa, they reduce the elastic effect of the
traditional rubber support ensuring excellent riding comfort. The elastic joints are contained by a cup made
of acetal resin which allows further damping of vibrations
without compromising wheel alignment. The central stainless steel shaft is fixed to the frame with 2 M10 screws replacing the original through screw. Designed
for Quattrini engine casings, they are compatible with Piaggio engine
casings. Check the size of the seat, it must not exceed diam.
39.25mm

The intake manifold, machined from solid, is provided already worked and ready to be installed. The reduced length and the particular taper of the duct improve the engine's response across the entire power range. Ideal for VHSB 34 LD carburetor or alternatively carburetors with a 44mm diameter connection. Compatible with all QUATTRINI reed valve cylinders for Vespa Smallframe.

Born for the track, it anchors to the engine casing on the engine pillar.
It comes with 2 anti-vibration mounts to be fixed on the bracket slots, and 2
raw sheet metal plates to be welded onto the exhaust in the ideal position.
Its total adjustability allows the exhaust to be positioned without tension, preventing it from breaking. Made of galvanized steel.

The CMX is defined as a turned clutch because the basket is integral with the gear (pinion). This technical choice allows the basket (commonly known as the
bell) to remain stationary when the clutch is pulled (clutch disengagement).
Thanks to this reversal of moving parts, the clutch
becomes much more progressive in the initial thrust phase of the Vespa
minimizing any annoying jerks at start-up
(a problem known to old-design clutches). This precaution,
together with the significant contact points of the lined discs and conducting discs,
makes the CMX an ideal clutch for engines with power
greater than 15 hp, avoiding premature wear caused by the
hammering of the contact parts.

In laser-cut steel

In galvanized metal.

Silent Blocks specifically created to eliminate the elastic effect that we feel on traditional models, all supported by 2 bearings held in place by an acetal resin bushing.
The attachment to the frame is done with two M10 bolts.
