Enertia, right -- that sweet electric motorcycle from Brammo? Well, a few years back the company slapped some dirt bike tires on this silent cycle (seen above) and taunted the world with the possibility of an Earth-friendly offroad ride. Such a creation never made it to market, sadly, but it looks like the company may finally be ready to deliver. The bike hounds over at Asphalt & Rubber were digging through the AMA MiniMoto SX supercross race list of entrants when they spotted the Brammo name... which is odd since the Oregon-based company's current vehicles are all street-only affairs. Guess Zero Motorcycles better watch its back, there may be new challenger for king of the electric dirt bike hill. We won't have to wait long to know for sure -- the Brammo team will be launching its latest creation through the muddy, hairpin turns at the South Point Arena in Vegas next week.
