58cc Honda Ruckus / Metro big bore piston kit BOLO-Race Farm

 If you were looking to get the most out of your Honda ruckus stock engine (GET) this sucker is a must! This will bump your engine from a 49cc to a 58cc. My first thought was, what is 9cc’s going to do!!! Let me tell you! This wakes it up! It’s not quite the power of a gy6 engine, but it will keep up with a 85cc metro big bore kit (2013-2015 metro). It’s pretty impressive! This piston is 18.5 % larger than stock. Unlike every other scooter on the planet, the Ruckus/Metro engine known as a GET engine does not have a removable cylinder unfortunately:-(. Your engine will need to be completely torn down and the cylinder sent to a machine shop to have the cylinder bored to to fit this piston. It’s not a walk in the park, but the results are amazing! We can also build a engine for you if you do t have the resources.
