Rounded corner, height--> 50.2 mm

Transmission gears in special straight-tooth steel with a
recalculated ratio. They completely eliminate any axial thrust, reducing the
stress on the bearings. Made with high precision machines, carburized, hardened, and ground to provide high characteristics of silence and
durability.

The brand new Malossi-like exhaust has been designed to add a touch of liveliness to our beloved ET3 without abandoning the classic torpedo shape. It has been studied from scratch, optimally connecting the manifold and exhaust, significantly increasing performance. Inside, two chambers have been created, separated by a bulkhead to maximize the

proper expansion of exhaust gases while minimizing the noise of the exhaust.

Complete damper kit

The brand-new Malossi-like exhaust has been designed to give a touch of zest to our beloved Vespa without abandoning the classic torpedo shape. It has been newly designed to best connect the manifold and exhaust, significantly increasing performance. Inside, two chambers have been created separated by a partition to optimize the

proper expansion of exhaust gases while minimizing exhaust noise.

Seals with special features, high quality
Low friction and with virtually unlimited lifespan.
FKM oil seals plus PTFE boast the use of the most
noble materials and the most advanced technologies, as well as the production quality
which has always been the strength and pride of Malossi.

For 19 cone shaft

Note: Made of special Magnesium aluminum alloy, with special friction
material containing metallic fibers that improve its resistance
properties, asbestos-free according to the new CEE standards.

Additional flywheel masses: allow you to customize the ignition to your vehicle based on the vehicle's preparation, further increasing the moment of inertia.
