Are you ready for take-off? The Zero MX Dirt Bike 2009 is about to take you to new heights and deliver a perfect landing every time you hit the ground. Extremely tough and lightweight, the MX is built on a handmade aircraft grade aluminum frame, making it super agile and fast. This Zero electric dirt bike uses a proprietary Z-Force lithium ion power pack for its juice, giving you plenty of speed as soon as you punch the throttle. Add to the mix a newly developed suspension system to smooth out all the bumps on the trails and terrain, and nothing will stand between you and the finish line. Other features include a hardened steel 420 chain, easy access to gauges and switches, and wider handlebars. Zero Motorcycles.
