Diaphragm Block -TOP PERFORMANCES-Tassinari Minarelli 50ccm (horizontal cylinder), Suzuki/Aprilia 50ccm.

Top Performances now offers with this diaphragm block a VForce 4 valve diaphragm. This is developed and patented by Moto Tassinari. Due to the considerable enlargement of the inlet opening a much better filling of the case is achieved. This leads directly to a noticeable increase in performance. The engine hangs more agile on the gas. Each gas surge is immediately converted into thrust.

The Venturi insert included in the scope of supply ensures an optimized gas flow and should therefore always be installed.
