Zero Motorcycles: 2011 Zero X Electric Dirt Bike Motorcycle

Zero Motorcycles: Where would you go with an exceptionally lightweight, highly maneuverable and powerful dirt bike? Now … what if it didn’t make a sound?

Built from the ground up for extraordinary handling, the fully electric Zero X uses a revolutionary powertrain to open up previously unthinkable trail riding possibilities.

Zero Electric MotorcyclesWith instant torque from a standstill, no shifting and a low weight, the Zero X is a high performance electric motorcycle that pushes technical trail riding to ambitious new levels.

Direct drive gearing and weight-optimized components combine to form a stealthy machine that aggressively races up hills, flies over jumps and cuts through streams.

A proprietary Z-Force™ lithium ion power pack and highly efficient motor are optimized to produce instant acceleration at the twist of your wrist. To extend ride times the aircraft grade aluminum Zero X frame is designed to accommodate quick power pack swaps.

What’s New for 2011

For 2011 the Zero X 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 X on the street. It includes lights, mirrors, higher gearing, a sidestand and street legal tires.

Both configurations of the Zero X are equipped with a new trail tuned suspension system and a powerful new braking system that allow it to take on technical single track like never before. An anodized aluminum power pack casing and bold new graphics package give it a fresh new look that polishes off the motorcycles’ host of improvements and systems upgrades.

Among its powertrain improvements, the Zero X offers the option of fast charging that cuts the recharge time by almost half to around one hour. Additional improvements include a more robust frame, higher grip footpegs with a standard clevis, handlebars with adjustable risers and an integrated ignition lock system.

Motor and Power Pack – High Torque and Acceleration

Fueled by Zero Motorcycles’ patented lithium ion power pack, the Zero X delivers incredible 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.

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

Suspension and Handling – Smooth ControlZero Electric Motorcycles

The Zero X uses a newly refined suspension system to absorb aggressive terrain on the trail. 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 trail
    • Tested on various trails by a variety of different experienced 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
  • Aluminum stanchions for reduced weight and superior control
  • Front adjustments: Compression and rebound damping
  • Rear adjustments: Preload and rebound damping

Improved contact points:

  • More supportive footpegs with an aggressive new profile
    • Much more aggressive saw tooth profile to maintain foot position and control
    • Uses a standardized clevis for greater aftermarket options
  • Higher handlebars with adjustable risers
    • Creates a more ergonomic riding position and allows for better control

Brakes – Bigger and More Robust

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 X 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

Frame and Body – Rigid and Light Aircraft Grade Aluminum

At the core of the Zero X 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.

  • More rigid and robust frame for 2011
  • 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 graphics and a revised number plate

Wheels and tires – Traction for Technical Trails

The Zero X comes with new tires and wheels on the front and rear for increased traction and durability. The result is quicker acceleration, faster hill climbs and more fun.

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 trail tires (front and rear)

New wheel and tire sizes:

  • Front: 1.85 x 19 wheel; 80/90-19 tire
  • Rear: 2.15 x 16 wheel; 90/90-16 tire

Gearing and Chain – Durability and New Aftermarket OptionsZero Electric Motorcycles

To accommodate the Zero X’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.
