This is a unique book, useful to all Lambretta owners and riders who mean to understand the evolution of the famous Innocenti scooter down to the smallest detail. After having digested all the technical information supplied by the concessionaires of the period, and having created thousands of illustrations showing all the versions produced by Innocenti between 1947 and 1971 piece by piece, the author has brought to life a guide that shows even the smallest modification carried out over the years on the various models that have appeared in the marketplace.
