Laverda Sport 650,668 Kevlar.... The best way to find a replacement that will interchange with the Weber-Marelli electronic injection system is to check these websites......668 tech.Laverda-nz.org/ and Laverdaman.co.uk. They should be able to get you the information you need for your sport bike. with a machine like the Laverda 650 Kevlar, you should go with a factory replacement pump, designed specifically for your high performance motorcycle.

Many thanks for yr response
