The "e-Stage N15" has been made more affordable by reviewing the parts configuration to make engine customization easier and more enjoyable You can enjoy the torque full output performance which is different from the stock engine.
Sports camshaft (N-15) is decompression-less specification.
This is a big bore kit which can change the displacement from stock 124cc to 143cc by changing the cylinder and piston. By installing the FI-CON 2 (Injection Controller) at the same time, you can achieve a torque-full output characteristic different from the stock. The cylinder is an aluminum steel sleeve cylinder. The surface of the cylinder is painted black like the stock.
The piston skirt is coated with molybdenum for better initial adhesion.
■Sports Camshaft (N-15) Decompressor This is the best profile to maximize the performance of the stock cylinder head and improve the output performance. The camshaft (N-15) does not have an auto decompression system, so it will not have decompression when installed.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
Top Quality parts, but most of all well engineered to create a cohesive outcome, there are many options out there but this piston from Takegawa maintains a great combustion chamber shape with the stock head, and includes a relief for the spark plug (so no spark plug spacer required). The result is a engine that runs as good as OEM Honda but has just a bit more go everywhere. In my specific kit the piston rings were mostly ok to go out of the box, If I was being picky I'd say the top ring was a tiny bit tight and the second ring was a tiny bit loose, the oil rings were perfect. As a result I opened up the top ring from 0.009" to 0.01" only becuase its going into a CT125 which naturally runs hot vs GROM/Monkey. But I think I could have run the rings out of the box and probably had zero issues. I also like that the piston is 4 grams lighter than the stock piston, this means the motor runs very smooth with little vibration. The N-15 cam is perfect for a OEM plus feeling, I've tried a range more agressive cams and the bottom end always suffers, in my opinion that does not suit the charater of the CT125 however, this N-15 cam is perfect for the CT125 imo. I like this kit so much I'm considering buying a second to keep in stock as nothing lasts forever. View Detail
