For those you that like to head out into the woods to ride a dirt bike but don't want any exhaust emissions, the Zero X may the answer to your needs. Zero Motorcycles has just released details on the 2009 edition of its electric dirt bike. After selling out its run of 2008 models, the new version gets a bunch of upgrades including a beefier frame and suspension. Even with a stronger structure made of aircraft grade aluminum, the bike weighs in at just 151 lbs. The electric motor turns the back wheel with 23 hp and 50 lb-ft of torque. Energy is packed into a 2 kWh lithium ion battery pack stuffed into the middle of the frame. A two-hour recharge should provide about 40 miles of range. Until the end of the year, the Zero X can be ordered for $7,450. Once the calendar flips over, the price goes up by $300.
