TrailMaster LX300 Dual Sport Dirt Bike
Description
The TrailMaster LX300 is a PRO-Series mid-size dual sport dirt bike built in collaboration with JHL Offroad, engineered for riders who demand serious performance without sacrificing reliability. At its core is the Zongshen NC300S balanced-shaft engine - a 283cc, liquid-cooled, EFI-equipped powerplant producing 23 horsepower through a smooth 6-speed manual transmission. Whether you're carving through trails, tackling motocross-style terrain, or commuting between adventure zones, the LX300 is built to handle it all.
This bike is loaded with race-grade hardware typically found on machines costing far more: inverted 54/60-950mm dual-adjustable front forks, CNC-forged alloy wheels, a CHOCHO 520HDS performance chain, and dual front and rear disc brakes with GG-grade pads. Street-legal-ready accessories including LED headlights, turn signals, rearview mirrors, taillight, and an LED speedometer make it a true dual sport machine. Weighing just 266 lbs, it strikes the ideal balance between agility and durability.

FAQ
Is the TrailMaster LX300 street legal?
The LX300 comes equipped with dual sport street-legal accessories including LED headlights, turn signals, taillights, rearview mirrors, and an LED speedometer. However, street legality depends on your local state and county regulations. We recommend checking with your local DMV or motor vehicle authority to confirm requirements before riding on public roads.
What is the Zongshen NC300S engine, and is it reliable?
The Zongshen NC300S is a well-regarded 283cc, single-cylinder, liquid-cooled, DOHC engine with a balance shaft that significantly reduces vibration. It features EFI (Electronic Fuel Injection) for precise fuel delivery and consistent starts. This engine is used in a number of performance-oriented off-road machines and has earned a solid reputation among enthusiast riders for durability and smooth power delivery.
Does the LX300 require assembly out of the box?
The LX300 ships partially assembled and will require some final assembly - typically attaching handlebars, mirrors, front wheel, and a few other components. Most mechanically inclined buyers can complete setup with basic tools. If you'd prefer professional assembly, we recommend visiting a local powersports dealership or shop.
How is the LX300 shipped?
The LX300 ships via freight on a pallet due to its size and weight. Delivery will typically be to a curbside location. Please ensure you have help available to unload the bike and move it to your desired location. Contact us at service@omahasportsandgames.com for a shipping quote or estimated delivery timeline before purchasing.
What is the seat height, and is this bike suitable for beginners?
The LX300 has a seat height of 37.43 inches (950mm), which places it in mid-size territory - accessible for average-height adults but potentially tall for shorter riders. It is a 6-speed manual bike with 23hp, so it is better suited to intermediate or experienced riders who are comfortable with manual transmissions and off-road riding. Beginners who are confident on manual bikes will find it manageable with practice.
What kind of maintenance does the LX300 require?
Like any liquid-cooled, EFI-equipped dirt bike, the LX300 requires regular oil changes (SJ 10W-40 recommended), coolant checks, chain lubrication and tension adjustment, brake inspection, and air filter cleaning. The CHOCHO 520HDS chain is a high-quality unit, but proper lubrication and tension are key to its longevity. Following the manufacturer's recommended service intervals will keep the bike running strong for years.
