TrailMaster MX250-Pro 250cc Dirt Bike - 5-Speed Manual, Dual Disc Brakes, Electric Start
Description
The TrailMaster MX250-Pro is a high-performance, mid-size motocross-style dirt bike built for riders who demand real power and premium components in one capable package. Developed in collaboration with JHL Offroad, this Pro-Series machine is powered by a Zongshen PR250 249.9cc air-cooled, 4-stroke balanced shaft engine that delivers 14 horsepower - plenty of muscle for trail riding, off-road adventures, and recreational track days. At just 266 lbs with a 35" seat height, it fits a wide range of riders without sacrificing capability.
Unlike entry-level bikes, the MX250-Pro steps up with an inverted 51/54mm adjustable front shock absorber, a nitrogen air gas rear shock, CNC alloy unbreakable levers, aluminum alloy rims and hubs, and a performance stainless steel muffler. Full motocross ergonomics paired with a race-tuned suspension system give this bike a natural, planted feel across every type of terrain - from hardpack trails to loose dirt and everything in between.
Key Features
- Zongshen PR250 249.9cc Engine: Air-cooled, 4-stroke, single-cylinder balanced shaft engine producing 14 hp at 8,000 RPM for strong, consistent power delivery.
- Electric Start with Kick Backup: Reliable electric start system with kick start as a backup - no fumbling to get rolling on the trail.
- 5-Speed Manual Transmission: Chain-drive gearbox lets riders dial in the perfect gear across a wide range of terrain and speed.
- Inverted 51/54mm Adjustable Front Fork: Pro-grade inverted front shock absorber delivers superior control and reduced unsprung weight compared to conventional forks.
- Adjustable Rear Air Shock: Nitrogen air gas rear shock absorber tunable to rider weight and terrain preference.
- Dual Disc Brakes: Front and rear disc brakes for confident, fade-resistant stopping in all conditions.
- Aluminum Alloy Wheels and Hubs: Lightweight YUANXING tires on alloy rims - 80/100-21 front and 110/100-18 rear - for proper motocross fitment.
- CNC Alloy Foldable Handle Levers: Unbreakable alloy levers that fold on impact rather than snap - a critical feature for off-road riding.
- 35" Seat Height / 13" Ground Clearance: Low seat height fits smaller and mid-size riders while ample ground clearance handles rough terrain.
- LED Headlight with Lens: Premium LED headlight for improved visibility on low-light trails.
