Check the length of spring cavity in the fork before purchase to ensure correct length

Some Laverda models used a 25.5mm spring with a metal sheath covering it. The sheath is not used with this spring and a shorter preload spacer is used to ensure correct ride height.

If your forks have emulators (Gold Valves) installed then the 50120000 Fork Spring is more suitable due to it's shorter length of 470mm
