POLINI carbon competition valves for minarelli am6 / vertical with big valve, MBK 51 with Athena housing

For those who choose the Italian brand POLINI, here are the valves for 50cc minarelli am6 motorcycle engine or vertical minarelli motor scooter (Big Valve). Its frame is in reinforced ABS, the slats are fixed via square nut screws, the slat stops are unfortunately present and not drilled, the slats are of very high quality carbon 0.30 and 0.35mm to choose from because both are delivered. We therefore recommend thick slats on engines that take very high speeds! The frame (box) is very well worked and short enough to unblock the rear transfer, we will regret the absence of an intake venturi.

Supplied with valve gaskets and 4 slats for adjustments.

The POLINI valve box can be mounted on several models :

-Mécaboite minarelli am6 engines

- MBK 51, AV10 moped engines with ATHENA housings

-The vertical minarelli scooter engines with POLINI Big Valve valve box
