I bought a '17 MX and put full LED lighting on it using a WP Lion battery under the seat as a total loss system. After a long day I through a battery tender on it and with in 30min it is fully charged again. This way it does not draw from the main battery and lose range. I ride mostly single track here in PA and it's suspension is very amenable to that. PA is not the easiest state to get a plate but I had no problem. It is plated and inspected now. The only thing I want to work on is some form of electric clutch to offer finer control over the power/wheelspin on really gnarly stuff. Overall I am ver happy with the MX converted to EX. My other bike for this purpose was a greatly modified KTM FreeRide 250r.
