🔥 Key Features
🏁 Zongshen 279.6cc EFI Engine
At the heart of the Crusader is a Zongshen NB300 279.6cc 4-stroke SOHC engine.
The liquid-cooled engine produces up to 19 kW (25.5 HP) and 24 N·m of torque, providing strong acceleration and usable mid-range power for off-road riding.
💧 Liquid-Cooled Performance
Unlike smaller air-cooled dirt bikes, the Crusader uses a liquid-cooling system designed to help manage engine temperatures during demanding riding conditions.
This makes it well suited for extended trail riding and higher-load operation.
⛽ Electronic Fuel Injection
The EFI fuel system provides precise fuel delivery while eliminating the need for manual carburetor adjustments.
Combined with electric start, the Crusader is designed for quick and convenient engine starting.
⚙️ 6-Speed Manual Transmission
The 6-speed manual transmission gives experienced riders complete control over the engine’s power delivery.
Select the appropriate gear for:
- Technical trails
- Hill climbs
- Open terrain
- Hardpack
- Sand and loose surfaces
- Higher-speed riding
Clutch and shifting experience is required.
⚡ Electric Start
Forget the pull cord.
The Crusader features electric start for quick engine activation and added convenience when stopping and restarting on the trail.
🛞 21”/18” Full-Size Dirt Bike Wheels
The Crusader uses the classic full-size dirt bike wheel combination:
21” front / 18” rear
The larger front wheel helps roll over obstacles and uneven terrain, while the 18-inch rear wheel provides traction and durability for aggressive off-road riding.
🏔️ 11.2” Ground Clearance
With 11.2 inches of minimum ground clearance, the Crusader provides additional room underneath the chassis when navigating rocks, roots, ruts, and uneven terrain.
🏍️ Inverted Front Fork
The front suspension uses a 37mm inverted USD fork designed to provide stiffness and control during aggressive off-road riding.
🔧 Adjustable Rear Monoshock
An adjustable rear monoshock with an internal bladder helps absorb impacts and maintain control over rough terrain.
🛑 Dual Hydraulic Disc Brakes
The Crusader is equipped with dual-piston hydraulic disc brakes at both the front and rear.
Front: 240mm hydraulic disc
Rear: 240mm hydraulic disc
The hydraulic braking system provides strong, consistent stopping power for demanding off-road conditions.
💡 Complete LED Lighting
The Crusader comes equipped with a complete lighting package, including:
- LED headlight
- LED tail light
- LED turn signals
- Horn
- Speedometer
The lighting system provides improved visibility during low-light riding where permitted.
🧱 High-Strength Steel Frame
The Crusader uses a double-cradle high-strength steel frame designed to provide rigidity and durability across demanding off-road terrain.
📏 Full-Size Ergonomics
The Crusader is built around a full-size dirt-bike platform with a 36.2-inch seat height and 53.9-inch wheelbase.
Its tall riding position provides additional ground clearance and a traditional dirt-bike riding posture.
Recommended for experienced riders who are comfortable with a tall seat height and manual transmission.
