At the end of 2004, Laverda introduced a cheaper REV series alongside the new M series, which had abandoned the MCS threshing drum that Laverda had long used. Instead, it featured a small REV drum, which was said to increase separation efficiency by 20%. The lineup included two 5-rib models and one 6-rib model. The design was considerably more traditional than the M series, both externally and in the cab.

Unlike the M series, all models were equipped with Iveco Common Rail diesel engines. The transmission had only three speed ranges. Laverda's traditionally used wooden bearings for the rasp bars were replaced with "self-lubricating strips." The standard equipment was nearly as comprehensive as in Laverda's more expensive series. For example, almost all adjustments were made electronically from the cab.

The lineup was also sold under the MF Activa and Fendt E series names.
