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!

-70mm cylinder

-70mm piston 

-70mm piston rings

-Circlip x2

-16mm wrist pin 

-Stainless steel head gasket

-Composite base gasket

Great quality and great customer service

In addition to having more power. My bike is now smoother and more stable at high speed. It’s happier at those higher rpm’s. I had a few questions about installation and motocult was happy to advise me of the right direction to go. Definitely Recommend to anyone with a CG!

WHAT I HOPED FOR

The machine work looked very good and of great quality.
highly recommend this to anyone looking to increase HP.
It was very easy to install and required no additional modification's during installation.
Would highly recommend this to anyone looking to improve your CG250 HP. You will need a higher quality carburetor for the larger displacement. preferable a PE28 nibbi carburetor. after some time and patience, the 2018 Magician is running very will.
