Zero Motorcycles: 2011 Zero MX Electric Dirt Bike Motorcycle

Responsive. Planted in the corners. Tuned for flight. Twist the throttle and start carving the track. Silent and powerful, the Zero MX opens a visceral new world of gritty possibility.

Zero Electric Motorcycles, zero dirt bikes, 2011 zero bikes, 2011 zero dirt, zero dirt bikes, 2011 zero mx bikeThe Zero MX takes revolutionary electric motorcycle technology to the track. Incredibly tough and lightweight, the Zero MX uses a newly developed suspension system to absorb aggressive terrain and give you an edge.

Combined with state-of-the-art Z-Force™ technology and an ultra-light frame design, the Zero MX is agile and fast where it counts.

Track tuned suspension and an industry leading power-to-weight ratio results in a dirt bike with uninhibited responsiveness.

During aggressive riding the advanced suspension system and alloy motocross wheels take the hits while smoothly maintaining control. Intensity combines with silence to open up a new world of riding possibilities.

What’s New for 2011

For 2011 the Zero MX comes in two new configurations; dirt only and street legal. The new street legal version marks the first time ever that riders can legally take a Zero MX on the street. It includes lights, mirrors, higher gearing, a sidestand and street legal tires.

Designed to ride harder, faster and longer, the 2011 Zero MX uses a new motor mounted Z-Force Air induction system to cool its more powerful Agni motor. With improved throttle control, new track tuned suspension and a new motor, the Zero MX tears out of corners with better acceleration and control than ever before. When it comes to stopping or slowing down, riders will be pleased to leverage a completely revamped and powerful new braking system that offers impressive performance under the most demanding of circumstances.

An anodized aluminum power pack casing and a bold new graphics package give the Zero MX a fresh new look that polishes off the motorcycles’ host of improvements and systems upgrades. Among its powertrain improvements, the Zero MX offers the option of fast charging that cuts the recharge time down to around an hour. Additional improvements include a more robust frame, higher grip foot pegs with a standard-size clevis, handlebars with adjustable risers and an integrated ignition lock system.

Motor and Energy– High Torque and Acceleration

Fueled by Zero Motorcycles’ proprietary lithium ion power pack, the Zero MX delivers instant torque from zero RPM. This is made possible by the power pack’s ability efficiently dump an incredibly high 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. A standalone charger integrates into this system and uses a specially developed charge profile to optimize the power pack’s recharge time.

Think of it this way, fuel systems are to gas motorcycles what electrical systems are to electrical motorcycles. Where others use a small carburetor and fuel pump, Zero uses a highly tuned fuel injection system. Zero has found a way of rapidly flowing more energy out of a power pack than any of its competitors. This means more acceleration and more fun.

More power and better acceleration:

  • More powerful Agni motor is standard
  • Sustains higher power output for longer durations
  • More torque

New motor integrated Z-Force Air Induction System:

  • Allows for increased motor performance during aggressive riding
  • Enables more energy output for longer durations
  • Powerful, low weight and compact motor

Enhanced power pack features include:

  • Optional quick-charge that cuts recharge time down by almost half (to around an hour)
  • Full aluminum anodized exterior casing
  • Increased durability and impact load resistance
  • New and improved internal packaging
  • Current-based state of charge sensor
  • CAN communication
  • Quick connectors for easier swap ability

Additional powertrain improvements include:

  • Simplified performance settings for more and less aggressive riding (Level I and II)
  • More refined power delivery
  • Enhanced motor with integrated thermal protection system
Brakes – Bigger and More RobustZero Electric Motorcycle

Because you’ll be going faster through the turns and riding harder with instant torque at any RPM, Zero has added increased stopping power and a more precise brake feel. The 2011 Zero MX electric motorcycle features beefier brakes all around.

More powerful and higher performance braking system by HB Performance:

  • More precise, easier to modulate and requires less effort
  • Increased fade resistance and greater thermal mass rotors
  • Steel braided lines for improved lever feel and precise brake modulation
  • Larger system size for increased stopping power
  • Greater commonality using standard-size mount patterns
  • Standard motorcycle rear foot brake
Suspension – Tuned for the Track

The Zero MX uses a newly refined suspension system to absorb aggressive terrain on the track. Taking advantage of the motorcycle’s low weight, the inverted front fork is robust, light and responsive. Riders can quickly dial it in using the externally adjustable compression and rebound damping. On the rear, a rigid double diamond swing arm keeps the wheel planted using a newly developed custom rear shock with a fully adjustable spring preload and easily tuned damping.

Carefully tuned, balanced and improved suspension system:

  • Specially tuned for the track
    • Tested on motocross tracks and jumps by a variety of different riders
    • Suspension specialists recorded all riding results alongside riders
    • Analysis of riding results used to optimize compliance by adjusting damping curves and spring rates
  • Revised triple-clamps for improved bearing pre-loading and durability
  • New fork and shock internals
  • Steel stanchions for increased strength, rigidity and control
  • Front adjustments: Compression and rebound damping
  • Rear adjustments: Preload, compression and rebound damping
Wheels and Tires – Hook Up in the Turns

The Zero MX alloy wheels are designed to reduce unsprung weight while not compromising on strength. During acceleration instant torque is efficiently channeled into the dirt through a beefy rear tire and directed using an equally aggressive front.

New improved wheels and tires

  • Stouter, more durable and more robust wheels by ProWheel
  • Standard sizes with commonality for greater aftermarket tire options
  • Aggressive new motocross tires (front and rear)
  • Street legal certified tires

New wheel and tire sizes:

  • Front: 1.85 x 19 wheel; 70/100-19 tire
  • Rear: 2.15 x 16 wheel; 90/100-16 tire
Frame and Body – Rigid and Light Aircraft Grade Aluminum

At the core of the Zero MX lies the ultimate dirt bike frame that Zero has engineered from the ground up and hand crafted using aircraft grade aluminum. The resulting combination of lower weight and higher strength means more responsiveness. In the turns and off the line this translates into greater acceleration. To make the frame even more durable each one is shot-peened and anodized.

  • Hydroformed top tube for increased strength and reduced weight
  • Massive swingarm for increased strength and torsional rigidity (better cornering and tracking)
  • Large cylindrical swingarm cross tube for increased stiffness and suspension response
  • Thru-axle rear hub for exponentially increased strength and rigidity
  • Entire frame is shot-peened and anodized for resistance to corrosion and abrasion
  • Organic frame gusseting for increased strength and smoother body lines
  • Bodywork is highlighted with new color graphics
Gearing and Chain – Durability and New Aftermarket Options

To accommodate the Zero MX’s increased traction and ability to accelerate in the dirt Zero uses a hardened steel 420 chain along with durable direct drive gearing. The result is a stronger and longer lasting drivetrain that puts the power from the throttle directly into the dirt.

  • Hardened steel 420 Chain
  • Front and rear accompanying 420 Sprockets
  • New motor sprocket cover that provides a more finished powertrain look
  • New rear sprocket that offers greater aftermarket options
    • Optimized to be light, stiff, strong and durable
    • Standard-size mount pattern for greater aftermarket options
Instrument Panel and System Upgrades – Quick Look and Easy Access

A quick look tells you everything you need to know when reading the Zero MX’s simple and durable instrument panel. Connecting the dash to the rest of the motorcycle is a brand new wiring system that is designed to increase electrical system longevity. With a motorcycle this desirable, you’ll also be reassured to know that it comes with an integrated keyed ignition switch and steering lock.Zero Electric Motorcycles
