The ultimate high-end intake system from Stage6 for Piaggio engines. The oversize reed valve spacer minimizes intake length, which makes for higher peak power as well as better throttle response. Due to the revised direction of the reed valve (towards the cylinder), better charging can be achieved.
The intake spacer, milled from solid material, is equipped with a revised Stage6 reed valve, which should not be removed. Also included is the SOFT version of the intake manifold as you know it from the carburettor and intake spacer kits for all Stage6, KOSO, PWK and Keihin flat-slide as well as VHST carburettors with a 24–28mm diameter (union size: 35mm).

Please note: To mount the intake system, you’ll first have to remove some of the engine block around the intake (in accordance with picture 5).
