Here is a video on how I replaced the stock handlebars on my Massimo MB200S. a crash had them tweaked and the headlight light assembly broken. the fender somehow was bent backwards into the tire so I took a dead blow to the bracket to straighten.

I found the bars on eBay, through ArkansasCycleWorld. they have an extensive inventory of small Dirtbike parts and I recommend them, here is a link to their store.
