about this
MotoCult has done it, we made a 70mm big bore kit for your air cooled CG250 engine. This is the highest quality big bore kit available.
MotoCult has done all the machining for you so you’ll have the perfect increase in compression and the cylinder bolts on without any modifications needed. This piston and cylinder package will add 21cc (almost 10%) more displacement to your 229cc stock engine. Not only does this kit offer more cc’s it also substantially increases the compression resulting in MORE POWER! The piston has a 16mm wrist pin.
*IMPORTANT-this will not fit a 167fmm-c engine. Some of the newer Hawk 250’s have this engine. Please ensure that your CG250 engine has a 16mm wrist pin. Returns will not be accepted if your engine has a 15mm wrist pin. This kit is for 16mm wrist pins only!
