Washer / U-washer 20 / 28 / 0.5 made of steel for spacing out the front racing variator on your Piaggio Ciao, Si, Bravo and Boxer moped / moped.
The Polini, Malossi and Pinasco racing variators often have the problem that the lowest distance between the pulleys in the rest position is greater than the width of the V-belt. This results in the V-belt rubbing on the variator bolt at low engine speeds and starting to flutter. As a result, the V-belt wears out more quickly, which can lead to a tear and thus prevent further driving.
