Wow a honda 125cc? That is a whole new ball game compared to these little 49-66cc engines. I've ridden plenty of honda's and Kawasakis, yamaha's etc and the first thing that comes to mind is a bicycle exploding under that kind of power! My old yz80 was putting out nearly 22 hp (100cc kit, fmf and stuff) and there is no way a bicycle could handle that kind of power, that i know of. Maybe you have some ingenious plan but man that scares me! My little yz would stand straight up from a dead stop! That kind of torque would twist a bike frame like a pretzel if you could even get the power to the ground! I sure would like to see it if it can be done! That would be something!
