Two-Stroke Power: Tuned for Enduro Racing The YZ250X is optimized for the unique demands of Hare Scrambles and GNCC® racing. The Yamaha Power Valve System (YPVS™)-equipped 249cc two-stroke engine is mated to a wide-ratio five-speed transmission for the ultimate cross country power plant.
Advanced Motocross-Derived Chassis Ultra-lightweight YZ250-spec frame features carefully engineered combination of aluminum castings, forgings and extrusions for the perfect balance of rigidity and flex. The industry-leading fully adjustable Speed Sensitive System KYB® spring-type front fork is matched with a fully adjustable high performance KYB® long-travel rear shock, both tested and tuned specifically for the needs of cross country racers.
GNCC®-Specific Features Cross country focused suspension setup, optimized YPVS™ settings, new lightweight Excel® wheels paired with Dunlop® Geomax MX33 tires, sealed O-ring chain, standard side stand and fuel tank petcock with reserve position all combine to make the perfect GNCC® racer.
New Brake System An updated high performance braking system features larger front pistons, a more rigid caliper and a redesigned 270mm front rotor with a 30% increase in pad contact area, all combining to provide exceptional braking power and feel. The redesigned rear rotor maintains the same braking power while dropping outer diameter from 245mm to 240mm, reducing unsprung weight with no compromise on performance.
Improved Rider Ergonomics To increase rider confidence in challenging cross country conditions, new smoothly integrated body panels, more narrow fuel tank design, slimmer shroud width and flatter seat all combine to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for better control.
Bold New YZ Styling Along with the slimmer, more aggressive bodywork, a new front and rear fender design and new radiator shrouds all integrate with a bold new graphics scheme to highlight the YZ family pedigree. Premium Yamaha graphics are now embedded to provide excellent durability and scratch resistance.
