NISSIN BRAKING SYSTEM
Equipped with a compact, lightweight, motocross-derived Nissin front brake setup that offers immense stopping power with excellent lever modulation.
CHROMOLY STEEL FRAME
Celebrated for its natural flex, the chromoly frame absorbs harsh energy that aluminum frames transfer directly to the rider, providing immediate confidence through high-speed rollers
SOFTER COMPOUND GRIPS
New, softer grips reduce rider fatigue and arm pump by absorbing trail vibration, allowing you to stay on the gas longer.
FACTORY GRAPHICS
Eye-catching red and black livery conveys an aggressive and contemporary image to accompany the launch of the 250 4-stroke
KYB SUSPENSION
The 48mm closed-cartridge front fork and 50mm rear shock offer industry-leading predictability, giving the rider maximum bottoming resistance on massive jumps while remaining plush over small acceleration bumps.
HEAVY DUTY CHAIN GUIDE
Features a reinforced structure to withstand mud, rocks, and hard impacts from ruts and logs. A straighter, stronger guide ensures final drive stability, prevents thrown chains, and protects the swingarm.
FLEXFIX HANDLEBAR MOUNTS
Handlebar risers utilize silent-block rubber mounts to isolate the rider's hands from engine vibration.
DUNLOP GEOMAX MX 34 TIRES
Next-generation Dunlop tires significantly improve cornering bite while shedding unsprung weight, allowing the suspension to react faster to acceleration bumps and square-edge chop.
