Reed manifold mrt on casing vespa smallframe two holes fitting, 28/30/32 diameter This article was put on the market after numerous bench tests. it is designed for achieving better fluid-dynamics compared to the traditional polini or malossi manifolds. it ensures better performance for those who prefer the reed intake and it can even match a valve intake in terms of power with additional stronger supply at low revolutions, which is typical of a reed injection. (of course, the comparison is with an engine with similar configuration.) in comparison with malossi and polini manifolds, mrt always provides 1.5 hp more and it improves over the whole time of use.the technical characteristics are as follows: - 4-flap reed valve with 0.40 reeds - manifold with flows guide - the valve holder was made and tested to achieve the best fluid-dynamics. it can be applied on two-hole casings, for all small frames without modifying the frame.
