I have a teether style killswitch wired up and positioned under my steering stabalizer on my handlebars and it seems to do fine its a pretty cheap mod mabee 30 bucks at the most
thats prolly your best bet but thats totally up to you man i like mine pretty well plus if you ever decide you wanna race it most places require a teether swith and nerfbars so if you install one your one step closer to being able to do that
