*Not compatible with JA65 (2023) model. *When used with SP Takegawa engine parts, air filter kit, or exhaust, FI-CON TYPE-e (injection controller) is required separately. *In the case of stock bike (stock engine / stock exhaust), injection controller is not necessary even if you change to big throttle body. *Images may contain other products. *Depending on the lot, the product may be delivered with the old price and label with the old JAN code before the price change. *There may be changes in product specifications due to the manufacturer's reasons.
The "Big Throttle Body Kit" improves power output performance just by installing it on a stock bike Simultaneous installation of engine parts such as camshafts, high-compression pistons, and big bore will further increase power output.
This product is SP Takegawa's original "Big Throttle Body" which is compatible with stock air cleaner box / connecting tube. SP Takegawa's original "intake manifold" and harness COMP. are included in the kit, so there is no need to modify the cowl or wiring at all. This allows for maximum extraction and increased power output. *Stock bike = stock engine / stock exhaust For stock bikes (stock engine/stock exhaust), simultaneous installation of an injection controller is not required even if the vehicle is converted to a big throttle body. Also, by installing SP Takegawa's big bore kit and big throttle body at the same time, the engine will run at high rpm without stress, which will further increase power output.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
Great fitment, very mind upgrade but well suited to the CT, I dont think the CT will ever be a bike you want big power from so having a mild TB option like this is nice. Looks factory would take someone very familiar with the CT125 to notice this TB on your bike. with the stock intake pipe I haven't noticed much of a perfomance boost so will address that next. I port matched mine although the port matching was pretty good out of the box. View Detail
Wanted to get a bigger throttle body to go with my bigger injector and more open exhaust. Very high quality parts as one would expect from SP Takegawa. The only thing that was disappointing was the factory mud guard that covers the throttle return spring will no longer fit as there is no place for it to bold onto the new intake manifold. Other than that I'm totally satisfied. I was able to use the factory rubber boot that covers the injector and injector plug but if you use the wire extension this comes with you wont be able to.View Detail
YOSHIMURAExhaust System and Clipping point's Sport camshaft are installed, so it is slightly different from the NORMAL car. Since a sub computer is also installed, I tried the setting in NORMAL for the time being. Not surprisingly, the Torque is thinner because the fuel is thinner. Therefore, Mr. Mukawa prepared the Mapping (Exhaust System + Cam + BigThrottle) was used as is. The result was a torque increase beyond our expectations, and we were able to traverse hills in 4th gear without any difficulty, and the high speed range was completely different. I'm sure it will be even better if I get the settings right, but since I don't have an air-fuel ratio meter, I'm going to try using the settings as they are for the time being. If you plan to Torque up without Bore up, it's definitely worth a try.View Detail
