Do you love your Honda CT125 Hunter Cub? If you do, but you wish that tiny little single cylinder engine packed just a little more of a punch, then you’re in luck. Over the months since the CT125’s introduction, Japanese aftermarket parts specialist Kitaco has come through with a bunch of assorted performance bits—and the latest are two big bore kits to help your Trail Cub realize its full potential.
Kitaco’s CT125 big bore kits come in two sizes: 164cc and 181cc. The complete kit for each version comes with the cast aluminum cylinder and matching piston in your selected size, an I-map injection controller, an O2 sensor feedback canceller, an oil cooler, and all necessary hardware (including piston rings and gaskets). Additionally, these parts were specifically engineered to fit all existing CT125s.
