When it comes to freestyle motocross (FMX), raw power, impeccable control, and lightweight agility are essential. Jackson Offroad, a respected name in extreme motocross customization, has taken the already formidable Yamaha YZ 250 and transformed it into a purpose-built machine ready to defy gravity. This revamped YZ 250 is no longer just a track racer—it’s a high-flying, stunt-hungry beast engineered to dominate ramps, dirt jumps, and freestyle competitions alike.
### Aggressive Tires for Maximum Traction and Control
A core requirement for FMX stunt riding is maintaining optimal traction during takeoff and landings. Jackson Offroad swapped the stock tires for a set of custom-engineered, soft-compound knobby tires designed specifically for freestyle terrain. These tires offer a balance between grip and flexibility, allowing riders to launch confidently off ramps and stick landings on dirt or mixed surfaces. Reinforced sidewalls provide additional durability for repeated hard impacts—an essential upgrade when landing from 40-foot aerial tricks.
To complement the aggressive tread pattern, wider rims were installed to stabilize the bike mid-air and ensure better contact with varied terrain. This setup gives riders more precise control while pulling off tricks like whips, flips, and nac-nacs, helping reduce the chance of slippage or misalignment during critical moments.
### Modified Suspension for High-Impact Landings
Standard motocross suspension isn’t always up to the challenge of freestyle abuse. That’s why Jackson Offroad went all in on upgrading the suspension system. The front forks were replaced with custom-tuned KYB SSS (Speed Sensitive System) units with increased rebound damping and compression settings specific to big-air landings. Meanwhile, the rear end features a reinforced swingarm paired with a high-performance mono-shock built to absorb the force of hard impacts without sacrificing responsiveness.
This suspension setup doesn’t just soak up massive landings—it helps riders maintain control on takeoff and during transitions, making tricks smoother and safer. Adjustability was also a key focus, allowing FMX athletes to fine-tune their settings based on jump size, ramp angle, and personal preference.
### Enhanced Power and Throttle Response
The Yamaha YZ 250 is known for its snappy two-stroke engine, but Jackson Offroad knew that in the world of freestyle, even more responsiveness is crucial. The engine was overhauled with a high-performance piston, race-tuned exhaust system, and re-jetted carburetor for crisper throttle response and a broader powerband. This means riders get a faster burst of torque when they need it—essential for short run-ups and precise timing during stunts.
A lightweight, FMF titanium exhaust system not only boosts horsepower but reduces overall weight, improving the bike’s aerial maneuverability. Coupled with a custom ECU remap, the new setup offers optimal fuel delivery for peak performance without sacrificing engine reliability—critical when every second counts during a run.
### Lightweight, Reinforced Frame and Safety Features
Weight reduction and durability go hand in hand for FMX bikes. The stock frame of the YZ 250 was reinforced at stress points and lightened with precision-drilled aluminum components. Subframe and pegs were modified for better ergonomics during mid-air adjustments, and a custom seat design allows riders to grip the bike better while airborne.
Safety was also a major consideration. Jackson Offroad added engine skid plates, radiator guards, and upgraded handlebar mounts to minimize damage in the event of a crash. A custom clutch and brake lever setup with fold-away designs reduces the risk of breakage on impact.
### Conclusion
Jackson Offroad’s custom Yamaha YZ 250 is more than just a dirt bike—it’s a freestyle weapon. With aggressive tires, finely tuned suspension, and a powertrain optimized for aerial stunts, this build sets a new benchmark for FMX performance. Whether it’s soaring over 75-foot gaps or executing backflips in stadium arenas, this YZ 250 proves that with the right engineering, even a classic can evolve into a modern stunt machine.
