I would like to replace the oem lego throttle with something better. I found the Tommaselli available at MG cycle however , there is not much detail on their site about fitment on the LMIII. Also, not sure if it is metal or plastic. Would prefer a metal bodied one. I realize I will have to get a separate switch gear for the start / kill functions. I believe I saw those advertised as well. I would greatly appreciate any advise or info . Dave
