TUNING SPORT – high-performance

For race use only. Not admitted in the area of the German StVZO! Product description
A high-tech product that’s made in Germany. Along with MMW,
MRP
has also adopted the T5, and is presenting
tuning cylinder heads
that are both high quality and can go into a variety of uses for both the Malossi 172cc kit as well as the Polini 152cc.

The cylinder heads are CNC milled from a solid aluminium block. A modern combustion chamber design with flat socket outlets guarantees and optimum output yield with an extremely low bell susceptibility at the same time. The compression and the squish band clearance are perfectly aligned to the corresponding cylinders.

For the optimum sealing, the heads are fitted with an O-ring seal. The MRP heads score points with a substantially enlarged cooling surface due to the cooling fins on both sides and an all-over air flow. The higher compression (1:11.5
12.5
with long stroke crankshaft) leads to more power in all rev ranges and a higher maximum performance.

Conclusion:
Whether it’s a plugged cylinder or a tuning set-up: these heads combine higher performance with a long lifespan. What more do you want
