Setup and Assembly
Your X-PRO Storm 150 Dirt Bike requires some assembly upon arrival. Follow these steps carefully to ensure correct and safe setup.

2. Removing Packaging and Securing Frame
Cut all plastic straps and zip ties securing the bike and its components to the metal frame. Use appropriate tools to unbolt the frame sections. Be cautious as the bike may shift once unsecured.
3. Front Wheel Installation
Locate the front wheel, axle, spacers, and nut. Align the front wheel with the forks, ensuring the brake rotor slides correctly into the brake caliper. Insert the axle through the fork and wheel hub, then secure it with the nut. Tighten firmly.
Important: Ensure the brake caliper is properly aligned with the rotor before tightening the axle.
4. Handlebar Assembly
Unpack the handlebars and the handlebar clamps. Position the handlebars onto the triple clamp, ensuring they are centered. Place the top clamps over the handlebars and secure them with the provided bolts. Tighten the bolts evenly to ensure the handlebars are firmly in place and aligned straight with the front wheel.
5. Front Fender Installation
Attach the front fender to the designated mounting points on the lower triple clamp using the provided screws. Ensure it is securely fastened.
6. Rear Shock and Chain Guard
The rear shock absorber is typically pre-installed. Verify that the top and bottom mounting bolts are securely tightened. Attach the chain guard if it is not already in place, ensuring it covers the chain effectively to prevent debris interference.
7. Battery Connection
Locate the battery compartment, usually under the seat. Connect the positive (+) red cable to the positive terminal and the negative (-) black/green cable to the negative terminal. Ensure connections are tight to prevent electrical issues. Replace the battery cover and seat.
8. Handlebar Pad Installation
Slide the handlebar pad over the center of the handlebars. This provides rider protection and a finished look.
Operating Instructions
Before operating your X-PRO Storm 150 Dirt Bike, familiarize yourself with its controls and safety features.
Pre-Ride Checklist:
- Fuel Level: Ensure adequate fuel in the tank.
- Oil Level: Check engine oil level using the dipstick.
- Tire Pressure: Verify tire pressure is within recommended range (refer to tire sidewall).
- Brakes: Test front and rear brakes for proper function and responsiveness.
- Chain Tension: Check chain for proper tension and lubrication.
- Controls: Ensure throttle, clutch, and gear shifter operate smoothly.
- Lights (if applicable): Verify headlights and taillights are working.
Starting the Engine:
- Turn the ignition key to the "ON" position.
- If cold, pull the choke lever to the "ON" position.
- For electric start, press the electric start button. For kick start, firmly push down the kick start lever.
- Once the engine starts, gradually push the choke lever to the "OFF" position as the engine warms up.
Shifting Gears:
The X-PRO Storm 150 features a 4-speed manual transmission. Familiarize yourself with the shift pattern (typically 1-N-2-3-4 or N-1-2-3-4). Use the clutch lever for smooth gear changes.
Braking:
The bike is equipped with disc brakes. Use both front and rear brakes simultaneously for effective stopping. Practice braking in a safe, open area to understand their response.
Maintenance
Regular maintenance is crucial for the performance, safety, and longevity of your dirt bike.
- Oil Changes: Perform initial oil change after the first 5-10 hours of operation. Subsequent oil changes should be done every 20-30 hours or as recommended in a detailed service manual (not provided here).
- Chain Maintenance: Regularly clean, lubricate, and adjust the drive chain tension. A properly maintained chain extends its life and ensures smooth power delivery.
- Air Filter: Clean or replace the air filter regularly, especially after riding in dusty conditions.
- Brake System: Inspect brake pads for wear and check brake fluid levels. Bleed the brake system if the lever feels spongy.
- Tires: Check tire pressure before each ride. Inspect tires for wear, cuts, or punctures.
- Fasteners: Periodically check and tighten all nuts, bolts, and fasteners, as vibrations from off-road riding can loosen them.
Troubleshooting
Here are some common issues and their potential solutions:
- Engine Not Starting:
- Check fuel level.
- Ensure ignition key is "ON".
- Verify battery connections are secure and battery is charged.
- Check spark plug for fouling or damage.
- Ensure choke is used correctly for cold starts.
- Loss of Power/Poor Performance:
- Check air filter for clogging.
- Inspect fuel lines and fuel filter for blockages.
- Verify proper carburetor tuning.
- Brake Issues (Spongy or Weak):
- Check brake fluid level.
- Inspect brake lines for leaks.
- Brake system may need bleeding to remove air.
- Check brake pads for excessive wear.
- Unusual Noises:
- Investigate loose fasteners.
- Check chain for proper tension and lubrication.
- Listen for engine knocking or unusual sounds, which may indicate internal issues requiring professional attention.
For complex issues, it is recommended to consult a qualified mechanic or contact X-PRO customer support.
