MSNBC story is slightly different. States that after hitting the car in the back, Corralas was thrown from the bike and struck an oncoming car. The cycle was recently bought and he did not have a Nevada drivers license or motorcycle license.
Yamahammer IT-175 or IT-200. 1986 was the last year they made them. Has a headlight and taillight (Enduro spec), but not street legal. Just put a old plate on the back and it will almost look legal.
Almost any street legal dirt bike will be a boat anchor compared to the off-road only models. KTM seems to be the exception, as their current enduro line up is street legal AFAIK. But then you're looking for an old bike.
The KDX was a good suggestion--not street legal though.
