DeNardis made SS series engines are built to same spec as Morini Franco S6 type engines. Our engines can be bolted into existing bike frames that used a S6 engine without any mounting issues. Most all parts from Morini S6 and DeNardis SS Series engines will cross reference. Huge parts inventory in stock and available for fast world wide shipping!

*Please note if switching out a S5 engine with a S6 or SS engine; the frame engine mounts, exhaust pipe and carb will need to be replaced or modified.
