TrailMaster LX300-Pro Dirt Bike - 283cc EFI, Liquid-Cooled, 6-Speed Manual


Description

The TrailMaster LX300-Pro is a full-size, pro-series dirt bike built for riders who demand race-ready performance without compromise. Developed in partnership with JHL Offroad, this machine is powered by the Zongshen NC300S - a 283cc, 4-stroke, 4-valve, double overhead camshaft engine with EFI and liquid cooling that delivers a strong, even 23hp across the rev range. A 6-speed manual transmission paired with a broad power band gives you precise control on any terrain, from hard-pack tracks to technical trail riding.

From the CNC forged alloy billet wheels and inverted dual-adjustable front forks to the GG-grade dual disc brakes and waterproof wire harness, every component on the LX300-Pro is spec'd for serious riders. At 266 lbs with a 37.4" seat height, it strikes the right balance between agility and stability for adult motocross and off-road use. Whether you're competing or pushing your limits on the weekend, the LX300-Pro is built to keep up.


Key Features

  • Zongshen NC300S EFI Engine (283cc / 23hp): Single cylinder, 4-stroke, 4-valve, DOHC with balance shaft and electronic fuel injection for consistent power delivery and easy cold starts.
  • Liquid-Cooled with Panasonic Cooling Fan: Water-cooled system with an aluminum alloy water tank cover keeps engine temps in check during extended hard riding.
  • 6-Speed Manual Transmission: Full-ratio gearbox with chain drive gives experienced riders complete control over power delivery in any condition.
  • Dual Start: Electric + Kick Backup: Electric start for convenience with a kick start backup - so you're never stranded on the trail.
  • Inverted Front Shock (54/60-950mm, Dual Adjustable): Premium dual-chamber inverted fork absorbers deliver motocross-grade suspension compliance and precision steering feel.
  • Rear Triple-Adjustable Shock Absorber: CNC aluminum alloy linkage rocker arm and rear shock system allow fine-tuned damping for your weight and terrain preference.
  • CNC Billet Alloy Wheels - KENDA 21"/18" Tires: GLM 7-series aluminum alloy CNC hub wheels wrapped in KENDA tires for reliable grip and durability on dirt and mixed terrain.
  • Dual Disc Brakes (GG Grade): Front and rear disc brakes with a rear rotor guard give you powerful, fade-resistant stopping power in all conditions.
  • 30 CrMo High-Strength Steel Frame: Chromoly steel frame offers the rigidity and flex characteristics needed for off-road abuse while keeping overall weight manageable.
  • CNC Forged Components Throughout: Upper and lower triple clamps, levers, handlebar, and rocker arm are all CNC machined from aluminum alloy for strength and precision fit.
  • Premium Accessories Included: LED headlight with lens, CHOCHO 520HDS high-performance chain, hand grip protectors, hour meter, engine bottom shield, and waterproof wire harness all come standard.

FAQ

Is the TrailMaster LX300-Pro street legal?

The LX300-Pro is designed as an off-road dirt bike and is not street legal in most states. It does not include the lighting or registration equipment required for on-road use. Always check your local and state regulations before riding on public roads or trails.

Does it come assembled or do I need to put it together?

The LX300-Pro ships partially assembled in a crate. Some final assembly is required, such as attaching the handlebars, front wheel, and mirrors. Most mechanically inclined riders can complete assembly with basic tools. If you're unsure, a local powersports shop can assist with final setup.

What is the difference between the LX300-Pro and the standard LX300?

The LX300-Pro is the PRO-Series version of the LX300 platform, featuring CNC billet alloy wheels, upgraded CNC-machined components throughout (triple clamps, levers, rocker arm), a performance stainless steel muffler, and a more comprehensive set of included accessories like the hour meter, engine bottom shield, and hand grip protectors. It's the more race-ready configuration of the two.

What oil does the LX300-Pro use and how often should I change it?

The LX300-Pro uses SJ 10W-40 motor oil. For a new engine, it's recommended to do a break-in oil change after the first 5-10 hours of riding, then follow regular intervals - typically every 20-25 hours of riding or as specified in the owner's manual. Always use quality 4-stroke motorcycle oil.

How is this bike shipped and how long does delivery take?

The LX300-Pro ships freight on a pallet due to its size and weight (gross weight 365 lbs). Delivery typically involves a freight carrier that will contact you to schedule a curbside drop-off. Lead times vary - contact us at service@omahasportsandgames.com for a current ETA and shipping quote before purchasing.

What age and experience level is the LX300-Pro appropriate for?

The LX300-Pro is a full-size, 283cc adult dirt bike with 23hp and a 37.4" seat height. It is intended for experienced adult riders comfortable with manual transmission and high-performance off-road bikes. It is not recommended for beginners or younger riders. Always wear appropriate safety gear including a full-face helmet, goggles, gloves, and protective riding gear.
