I have done a few offroad motors for guys in the onroad circuit and they have worked very well. If you want to send your motor in, we can make it work in the onroad scene. Other motors I have done for onroad include the Picco P7, RB S7 and the Novarossi P5X. The S5 should work very well when done. Check out my website and if you have any questions, feel free to contact me.
