Product reviewsBENELLI 491 Sport 50cc Pre 03 70cc Big Bore Cylinder Piston Gasket Kit

MarkymarkAerox

Hi. I fitted the kit and it works great.
The only thing I would recommend is that when u buy a Naraku piston kit, buy the top part of the engine from them too. For my bike it was £25.
Its woth it! It comes with i bigger circumference where the piston meets it. I tried using the kit with the original aerox yq50 head and there was a bad banging in engine until i changed it for the Naraku 70cc head and now it sounds and works really good. Just trying to save you doing the job twice like i had to. Hope ive been helpful😊Read full review...
