1 . Fixed Pulley

The 102mm-diameter, fixed, 15mm pulley is nitride hardened to produce excellent levels of durability, has a positive double “D” mount on the hub and is secured with an M24 galvanized nut.

2 . Torque Driver

This consists of a 15° pulley with a diameter of 102 mm, which is TIG welded to a specially designed hub with a mould-pressed EKU bushing. EKU is a dry self-lubricating material that ensures excellent sliding properties and minimal wear.
Adaptable even to the original Piaggio system.

3 . Variator Contrast Spring

The springs, made of high-carbon silicon-alloy steel and are heat-treated, are dynamically balanced, stove-enamelled and designed for each specific application.

4 . Fly Clutch

Fly Clutch consists of three new clutch shoes that use the Fly Malossi system. Designed with a specific shoe, it is coupled with Malossi springs to operate at a pre-established optimum RPM hook-in point. Once mounted on the hub assembly, the shoes are secured in position using a reinforced ring, which makes the entire assembly rigid.

5 . Assembled Fixed Hub

This is the main structural component of the clutch.
Its multifunctional elements include: a clutch shoe plate, a chrome hub in which the moving pulley operates and a clutch bell that allows the kick-starter pedal to engage and lock.
The assembly is TIG welded to the tightest tolerances to ensure perfect alignment. The pivot pins for the shoes have been increased in diameter by 6.5 mm and specially designed to be riveted and maintain alignment.
A primary gear shaft rotates within the unit that is held using two 13x19x12 needle bearings, providing increased rigidity.
Two oil seals ensure a sealed environment for Malossi lubrication.
