Tuning cylinder head from MRP for Vespa T5 with MALOSSI 172 ccm or POLINI 152 ccm Cylinder. CNC-milled high-tech Cylinder Head made in Germany for more power and better cooling.

High-tech made in Germany: In addition to MMW, MRP has also taken on the Vespa T5 and offers high-quality, versatile tuning cylinder heads for the MALOSSI 172 ccm kit and the POLINI 152 ccm Cylinder. The heads are CNC-milled from a solid aluminum block and are precisely matched to the respective cylinders.

• CNC-milled from solid aluminum
• Modern combustion chamber design with low ringing susceptibility
• Enlarged cooling surface thanks to cooling fins on both sides
• Higher compression for more power in all engine speed ranges

The MRP Cylinder Heads have a modern combustion chamber design with a flat bellmouth outlet. This ensures optimum power output with a very low susceptibility to ringing. Compression and squish edge are perfectly matched to the respective Cylinder and make the heads interesting both for plugged setups and for more powerful tuning engines.

The heads are fitted with an O-Ring gasket for optimum sealing. Another advantage is the significantly larger cooling surface: cooling fins on both sides and a full-surface air flow reliably support heat dissipation. The higher compression ratio of 1:11.5 to 1:12.5, depending on the setup with Long Stroke Crankshaft, ensures more power in all speed ranges and a higher maximum output.
