Intake Manifold CRIMAZ M-Racing

Cristian Mazelli is a dedicated Vespa enthusiast and he has been most active on the Italian scooter racing scene for many years. During his time as a racer he was constantly faced with material and part quality problems he deemed as unsuitable for the task in hand. To ease these bottlenecks in supply he decided to use his career-based knowledge of industrial research and development to create parts under his own name that he now markets under the 'CRIMAZ' logo. Beautifully detailed solutions combined with very high production quality are the results!

This 'M-Racing' reed-valve manifold by CRIMAZ is compatible with all QUATTRINI cylinders equipped with six bolting points for the manifold positioning. It is intended to be combined with the original QUATTRINI reed-valve assembly. The carburettor can then be mounted directly onto the cylinders flank, so creating an extremely short intake distance.

The frame of the Vespa to which it is then fitted will first require modification due to the increased overall dimensions of the engine unit. We strongly recommend this work be completed by a person with knowledge and experience of such jobs to avoid expensive mistakes! Ideally this manifold should be combined with a Dell?Orto VHSB 34mm carburettor. Internal diameter : 34mm, connection diameter : 44mm.
