2011 Zero MX Review


Fueled by Zero Motorcycles’ proprietary lithium ion power pack, the 2011 Zero MX delivers instant torque from right off the line. This is made possible by the power pack’s ability to efficiently dump an incredible amount of power as soon as you twist the throttle. Using an advanced monitoring system, each cell in the power pack is individually controlled during charge and discharge.

This is fun bike to ride and will keep up with any gas-powered bike on the track, however the company’s 30- to 60-minute riding range seems a bit lofty. If the Zero MX is ridden hard, it’s more likely to only get about 15 minutes of ride time. In cases like this, it behooves the rider to buy a second battery pack, just for those extra-long sessions. All it takes is unscrewing one knob, sliding out the bar the knob secures, unclipping the battery from the controller and out slips the battery.

One of the main benefits to the Zero MX is how little noise it makes. Most won’t even notice the motor is running except for the hint of a buzz. This can be especially appealing to riders who are looking to relax during their rides and would like to take in a bit more scenery. If you’re looking for a bike so you can just hang out with on your local track, this is the one you should be eyeing.
