This Stage6 inlet manifold is CNC-milled from solid aluminium and with a very sturdy high quality carburettor installation stub made of FKM (Viton®). 
The spacer lets you directly install a carburettor facing the rear wheel without the carb being at a too low angle that would result in overflow.

Special attention has been paid to the design of the intake tract, it hasn't been simply drilled through, but runs in a flow optimised design through intake manifold and spacer.

This version has been designed for short Piaggio engines (Zip, Vespa ET2/LX) These have been proven on the track where tyres expand and can rub on the float bowl.

Orange anodised.
