Fully Automatic with Reverse — Press, Twist, Ride

No manual clutch, no gear shift learning curve. The Thunder 125's fully automatic transmission lets first-time and experienced riders alike focus on the trail rather than the gearbox. Hand-operated reverse takes the stress out of tight spaces, trail exits, and storage maneuvering.

No clutch, no gear shifting to learn — hand-operated reverse means storage, tight trails, and parking spots stop being a problem the moment you press start.

Guangyu 119.6cc 4-Stroke Engine — Consistent Power, Zero Overheating

The air-cooled Guangyu single-cylinder engine has powered X-PRO 125cc ATVs reliably since the ATV-P011 line launched. 5.3kW at 7,500 RPM and 8.0 N·m of torque at 5,500 RPM deliver 35+ mph on flat terrain, while the air-cooling design manages heat naturally through extended sessions — no radiator maintenance required.

The same proven 119.6cc engine that's powered X-PRO's 125cc lineup since the ATV-P011 line launched — reliable starts and no radiator to maintain.

LED Headlights + Tail Light Standard — Ride When You Choose, Not Just When It's Bright

Factory-standard LED headlights and rear tail/brake lights extend your riding window from first light to last light. The LED beam illuminates the trail ahead clearly; the tail light keeps you visible from behind. No time-of-day restrictions on when you can safely ride.

Standard LED lighting most competitors treat as an optional upgrade — the trail doesn't end when the sun does.

19"/18" All-Terrain Tubeless Tires — Big Wheels, Real Off-Road Capability

Where some 125cc ATVs compromise with 16-inch wheels, the Thunder 125 runs proper 19-inch front and wide 18-inch rear tires — the same size found on mid-range sport ATVs. More ground clearance, more contact patch, more traction on the terrain that matters.

19-inch front, 18-inch rear — tire sizes borrowed from mid-range sport ATVs, not the 16-inch compromise found on many 125cc competitors.

Rider Fit Guide

Recommended Age	12 Years Old & Up
Recommended Height	Estimated 4'10" to 6'0" (147–183 cm)
Maximum Weight Capacity	Under 198 lbs (90 kg)

Teen and adult riders ages 13+ who want a complete, LED-equipped automatic ATV with 19"/18" off-road tires and reverse capability. Lightweight adult riders under 198 lbs seeking an entry-level gas ATV for farm use, rural property access, or recreational off-road riding. Parents who want a speed-limiter-equipped ATV with kill switch safety for their teen rider, and riders upgrading from smaller-displacement 110cc ATVs who want a larger engine and bigger tires without a price jump.

Always ensure the vehicle's engine size, speed rating, and weight capacity are appropriate for the rider's age, size, and experience level. Adult supervision required at all times.

Description

The X-PRO Thunder 125 is a 125cc gas ATV with fully automatic transmission and true reverse gear — no manual shifting. The Guangyu 119.6cc engine produces 5.3 kW at 7,500 RPM and 8.0 N·m of torque. Top speed 35+ mph depending on rider weight and terrain.

LED LIGHTING: The Thunder 125 includes LED headlights and a rear tail/brake light as standard equipment — not an upgrade. LED brightness and longevity extend the riding window into lower-light conditions before sunrise or after sunset.

SAFETY: Wireless remote kill switch for parent control from a distance, plus a handlebar-mounted engine kill switch for direct rider control. Adjustable speed limiter included.

TIRES & SUSPENSION: 19-inch front and 18-inch rear all-terrain tubeless tires — sizes typically found on mid-range sport ATVs, not the 16-inch tires common on many 125cc competitors.

Why Buy From Us

Company History

The company behind X-Pro has been operating in the U.S. motorcycle and powersports market for over 20 years. We are a licensed U.S. motorcycle dealer, not a dropshipper or a temporary marketplace seller. Our operations include product sourcing, compliance review, warehousing, fulfillment, after-sales support, and a dedicated parts inventory — all managed in-house from the United States.

The X-Pro Brand

X-Pro was established in 2018 as a dedicated powersports brand, built on over two decades of hands-on experience in the U.S. motorcycle and powersports market. The product line includes mopeds, scooters, dirt bikes, motorcycles, ATVs, go-karts, and electric powersports vehicles — all sold with full dealer backing.

When X-Pro entered the market, the affordable powersports space in the United States was largely defined by short-term sellers offering products with no replacement parts, limited or no after-sales support, and inconsistent quality control. Riders who wanted reliable support had to pay premium prices from established brands. X-Pro was built to bridge that gap.

Warehouses & Fulfillment

We operate two company-owned warehouses — one in California and one in Texas. These are not third-party logistics (3PL) facilities; they are staffed and managed by our own team. Inventory is stored, quality-checked, and shipped directly from these locations, giving us control over packaging, inspection, and delivery timelines across the continental United States.

After-Sales & Warranty

Every complete unit is backed by a manufacturer warranty. Warranty claims and support requests are handled by our U.S.-based team — customers contact us directly through our website or marketplace messaging, and our team has access to inventory systems, warehouse operations, and product records to resolve issues efficiently.

Parts Availability

We maintain a full replacement parts inventory at our U.S. warehouses. Parts are stocked before vehicles are listed — not ordered from overseas after a customer reports an issue. Parts orders ship from the same facilities that handle complete units.

Warranty

Every X-Pro complete vehicle is covered by a Limited Warranty: • Warranty Type: Limited Warranty • Frame: 1 Year (structural defects) • Parts: 90 Days (manufacturing defects, non-wear parts) • Battery: 90 Days • Exclusions: Wear items (tires, brake pads, chain, bulbs, batteries), damage caused by accidents, misuse, unauthorized modifications. • Warranty Policy: https://xprousa.com/pages/warranty-plicy Warranty claims are handled directly by our U.S.-based support team.

View full warranty policy

Limited Warranty covers manufacturing defects only. Normal wear and tear, damage from accidents, misuse, or unauthorized modifications are not covered.

Before You Buy

1 · Stay Connected

After your order ships, our team will contact you by phone and email to coordinate freight delivery. A valid, reachable phone number is required for LTL freight delivery; without it, the carrier cannot schedule your delivery appointment.

2 · Shipping & Delivery — LTL Freight

Your vehicle ships via LTL (Less-Than-Truckload) freight from our U.S. warehouse — this is not FedEx or UPS Ground. LTL freight delivers to the curb or driveway, not inside your garage or home. The carrier will call to schedule a delivery appointment; you must be present with a valid ID to receive the shipment. Inspect the pallet and packaging before signing.

3 · Assembly & Setup

Professional mechanic assembly is highly recommended. Regardless of who assembles it, you must tighten all bolts and apply thread-locker (Loctite) before the first ride. Vibration will loosen factory settings during use — this is a required pre-ride step, not a defect.

4 · Engine Maintenance — Gas Models

Before the first ride, check the engine oil level. Use 87 octane or higher unleaded gasoline — do not use E85 or high-ethanol blends. Inspect all bolts and apply thread-locker (Loctite) before the first ride. Change the engine oil after the first break-in period.

5 · Real-World Performance

Top speed figures are measured under optimal conditions with an average-weight rider on flat terrain. Actual performance varies based on rider weight, terrain type, incline, and temperature.

6 · Storage

For long-term storage (30 days or more), drain or use a fuel stabilizer in the tank. Store the vehicle in a dry, covered location. Disconnect the battery if storing for more than 30 days.

7 · Safety, Rider Requirements & California Restriction

Riders under 18 must be supervised by a parent or guardian at all times. Always wear a properly fitted, approved helmet and full protective gear — helmet is not included. This vehicle is for off-road use only and cannot be registered or operated on public roads.

8 · Break-in Period

We recommend a break-in period for the first few hours of riding. During break-in, avoid sustained full-throttle operation. After break-in, re-inspect and re-tighten all bolts and change the engine oil.

FAQ

What is the difference between the Thunder 125 and the Blast 125?

The Thunder 125 (ATV-P011) and Blast 125 (ATV-P004) share the same CT125-4 platform, 119.6cc Guangyu engine, 198 lb capacity, and 27.5" seat height. The Thunder 125 has been on the market longer (Amazon ASIN B07V2CTTW1, listed since approximately 2018-2019) and has accumulated more buyer reviews, making it a well-validated choice for buyers who want to read real-world experiences. The two models differ primarily in body styling and color lineup — contact our team for a full feature comparison.

What is the maximum weight capacity?

The Thunder 125 supports a maximum load capacity of 198 lbs (90 kg). This is significantly higher than many sport-style 125cc ATVs in this price range that cap at 132 lbs, giving the Thunder 125 room for larger teenagers and light adult riders.

How fast is the Thunder 125, and can the speed be limited?

The Thunder 125 has a top speed of 35+ mph depending on rider weight and terrain. Yes, a built-in speed limiter allows restricting the maximum throttle opening for beginning riders. We recommend setting a conservative limit initially and increasing gradually as riding skills develop.

Does the Thunder 125 have a remote control kill switch?

Yes. The Thunder 125 includes a wireless remote kill switch, confirmed in both the Specification and Safety sections of the product data, allowing a parent or guardian to shut off the engine remotely. It also has a handlebar-mounted engine kill switch for direct rider control — two independent safety systems.

What are the wheels and tires on the Thunder 125?

The Thunder 125 is equipped with 19×7-8 tubeless front tires and 18×9.5-8 tubeless rear tires mounted on steel rims with trim covers. These are full-size off-road ATV tires — significantly larger than the 16-inch wheels found on some competing 125cc ATVs in this price range. The larger tires provide more ground clearance (3.54 inches), better traction on unpaved surfaces, and improved stability at trail-riding speeds.

Is the Thunder 125 street legal?

No — the Thunder 125 is designed for off-road use only. It is not legal for operation on public roads, streets, or highways. Use only on private property, approved off-road areas, or designated riding trails. Always verify local regulations before riding.

Can I buy the Thunder 125 in California?

No — CARB regulations prohibit the sale of the Thunder 125 in California. It is EPA-certified for all other U.S. states.

How much assembly is required?

The Thunder 125 arrives approximately 85% pre-assembled. Remaining assembly includes 4 wheels, handlebar clamp, front bumper, rear rack, front shocks (2), rear shock (1), and battery connection — typically 45-60 minutes with basic hand tools. Search "X-PRO Thunder 125 ATV Assembly" on YouTube for video guidance.

What colors are available?

The Thunder 125 is available in 6 colors: Black/Red, Blue/Blue, Red/Red, Green/Green, Orange/Orange, and Pink/Pink. All colors feature powder-coated frames.

What fuel does the Thunder 125 use?

Regular 87 Octane unleaded gasoline, 2-liter fuel tank capacity. No oil-fuel mixing required — 4-stroke engine. Check and top off engine oil before riding. An oil change after the break-in period (first 2 tanks of fuel) is strongly recommended.

What warranty is included?

The Thunder 125 includes X-PRO's standard limited warranty: 1-year frame warranty for structural defects and 90-day parts warranty for manufacturing defects. Wear items (tires, brake pads, chain, spark plugs, bulbs, batteries) and damage from accidents, misuse, or modifications are not covered. X-PRO maintains OEM spare parts in U.S. warehouses in California and Texas.

Are replacement parts available?

Yes — X-PRO maintains OEM spare parts for the ATV-P011 / CT125-4 in U.S. warehouses in California and Texas. The Thunder 125 shares many parts with other CT125-4 platform models — Blast 125 (ATV-P004), Leopard 125 (ATV-P008), and Hawk 125 (ATV-P003) — meaning parts availability is broad. Order through xprousa.com or powersportsmax.com, or contact U.S. support directly.

What is the break-in period for the engine?

We recommend a break-in period of approximately 2 hours of riding (first 2 full tanks of fuel). During break-in, avoid sustained full-throttle operation, vary your speeds, and allow the engine to cool periodically. After break-in, change the engine oil before continuing regular use. Proper break-in significantly extends engine life.

Does the Thunder 125 have a front cargo rack?

No. The Thunder 125 includes a rear cargo rack as standard equipment — the assembly parts list does not include a front rack. The X-PRO Hawk 125 (ATV-P003) explicitly includes both front and rear cargo racks if dual racks are important.

Is the Thunder 125 good for beginning riders?

Yes, with appropriate supervision. The fully automatic transmission eliminates clutch management, and the electric start removes pull-cord difficulty. The adjustable speed limiter lets new riders start at a safe speed ceiling and build up gradually. We recommend all new riders complete ATV safety training and always wear a properly-fitted helmet, gloves, jacket, and riding boots.

Other X-PRO Models

Model	Best For	Key Difference
X-PRO Storm 125	Riders who want a lighter-duty option with a different platform.	165 lb max load (vs. 198 lbs on the Thunder 125) — built on its own CT125-8 platform rather than the CT125-4 platform Thunder shares with Blast, Hawk, and Leopard.
X-PRO Hawk 125	Riders who want the widest color lineup in the family, including Spider and Tree Camo patterns.	Same CT125-4 platform and 198 lb load as the Thunder 125 — differs mainly in color lineup (9 options vs. Thunder's 7) and a 3-layer safety marketing angle.
X-PRO Orca 125	Riders who want extra ground clearance and a lower seat height.	165 lb max load (vs. 198 lbs on the Thunder 125), 5.3" ground clearance, and 8 color options — built on the newer CT125-7 platform.
X-PRO Leopard 125	Riders who prefer a sport-style body on the same CT125-4 platform.	Same 198 lb max load and CT125-4 platform as the Thunder 125, in a sport-style body with Orange/Orange and Green/Green color options.
X-PRO Blast 125	Riders who want the same core spec sheet as the Thunder 125 in a different body style.	Functionally near-identical to the Thunder 125 (same CT125-4 platform, 198 lb load, 19"/18" tires) — the difference is body styling and color lineup, not specs.
X-PRO 110 ATV	Younger or smaller riders who need a lighter, lower-seat-height machine than the 125cc Thunder 125.	110cc engine (vs. 119.6cc), 143 lb max load (vs. 198 lbs), 21.26" seat height (vs. 27.5"), and forward-only transmission — no reverse gear.
