Opening Hook

Are you ready to conquer the trails with a dirt bike that blends thrilling performance, rugged durability, and rider-friendly design? At Arlington Power Sports, we proudly bring you the TrailMaster Pro Series Dirt Bike TM-LK140, a mid-size machine engineered for off-road enthusiasts who crave adrenaline without sacrificing control.

Whether you’re a teen stepping up to your first powerful dirt bike or an adult who loves weekend trail rides, the TM-LK140 strikes the perfect balance of youthful agility and grown-up performance.

Power in the Core: Engine & Drivetrain

At the heart of the TrailMaster TM-LK140 sits a Zhongshen/Yinxiang 140cc single-cylinder, 4-stroke engine, air and oil-cooled for maximum reliability on long rides. Delivering 6.8 horsepower at 7,500 RPM and 9.7 Nm torque at 5,500 RPM, this dirt bike ensures punchy acceleration while staying highly manageable for riders of different skill levels.

Key highlights:

• Dual starting options: Electric start for convenience, plus kick-start backup for reliability.

• 4-speed manual, non-circulate gearbox with chain drive for direct power transfer.

• CDI ignition system for consistent performance.

This combination gives you a responsive, engaging ride that’s built for dirt tracks, rocky trails, and open fields alike.

Suspension & Handling: Built for Off-Road Thrills

No dirt bike is complete without the right suspension setup, and the TM-LK140 doesn’t disappoint. With an inverted front shock absorber and a nitrogen-air gas rear shock with aluminum linkage, the bike absorbs bumps, jumps, and rugged terrain while keeping your ride smooth and controlled.

This suspension system makes the TM-LK140 a trail-conquering machine, ideal for riders who love speed, agility, and comfort even on uneven paths. Whether you’re tackling rough trails or enjoying casual off-road riding, this bike has you covered.

Rugged Build: Frame, Wheels & Brakes

The TrailMaster Pro Series TM-LK140 is crafted with a high-quality steel frame, providing a lightweight yet tough foundation. Pair that with alloy rims and hubs for added strength, and you’ve got a dirt bike ready to withstand the toughest conditions.

• Wheels/Tires: 17-inch front and 14-inch rear alloy rims fitted with YUANXING tires (70/100-17 front, 90/100-14 rear) for superb grip.

• Braking: Reliable front and rear disc brakes for powerful, safe stopping power.

• Extras: Stainless steel muffler for durability and foldable alloy handle levers for rider safety and comfort.

This rugged build ensures you have the confidence to push limits while staying in control.

Rider-Friendly Design: Size & Maneuverability

With a seat height of 32.9 inches and ground clearance of 13.3 inches, the TM-LK140 is ideal for teens and adults who want a bike that feels approachable yet powerful. At 171.6 lbs (net weight), it’s lightweight enough to handle sharp turns and jumps while maintaining solid stability.

Additional highlights:

• Fuel capacity of 1.56 gallons for longer trail sessions.

• Minimum turning radius of 1,900 mm for nimble handling.

• Compact dimensions (69.4" L x 28.9" W x 42.9" H) for easy maneuverability.

This makes it an excellent choice for those who want a serious dirt bike without stepping into the heavyweight category.

Stylish & Practical: Colors & Assembly

Style matters just as much as performance—and the TM-LK140 delivers with four bold color options: Red, Blue, Green, and Orange. Whether you want to blend into the forest or stand out on the track, there’s a look that suits your personality.

At Arlington Power Sports, the bike is priced affordably (around $1,599) and we also offer professional assembly with PDI for just $199, so you can ride confidently straight from our showroom floor.
