This cable worked with modifications to a 2017 ttr50. I have the dual cable from the factory and put protaper bars on my sons bike. I bought the cable along with the twist throttle which I'm still waiting on that to get shipped. But to install this on a 2012+ TTR50 you will need to modify the carburetor. Use the bottom cable on the carburetor and cut the top cable off and I used RTV to seal it from getting water in the carburetor. Also this cable is for a top mount throttle on carburetor. Easy fix just bend the tube straight like I did and install pretty easy.
