I'm not one to customize but the headlights and turn signals are absolutely mandatory. OEM parts and Thailand should be easy to import and cheap.projector headlights off of the MSX125 would be on the very top of my list, seeing how projector headlights are available there's no way I will just stick to the stock halogen headlights.

The alarm I have was £5 / USD8 on ebay with a remote control to turn it on/off. Battery operated on a 9v battery. I put a voltage regulator in it instead and wired to the bike battery. I only use the alarm when I leave a bike at the railway station / shops. It goes off for 30 seconds and resets when movement stops.Not a bad idea I would hate to lose my grom to some thief. a good chain and padlock sounds good. An alarm would piss people off though.
