• Two-Stroke Agility: Tuned for Cross Country and Hare Scrambles Racing: The YZ125X is optimized for the unique demands of Hare Scrambles and GNCC racing. The YPVS-equipped 125cc two-stroke engine is combined with a six-speed transmission for the ultimate cross country power plant.
• Lightweight Aluminum Frame: Ultra-lightweight YZ125-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, the KYB speed sensitive spring-type suspension is tested and tuned specifically for the needs of cross country racers.
• GNCC-Specific Features: 18-inch rear wheel, sealed O-ring chain, off-road focused tires and suspension settings, a standard side stand and fuel tank petcock with reserve position are perfect for GNCC racing.
• Industry-Leading Suspension: Yamaha's renowned spring-type KYB fork is matched with a long-travel shock, both fully adjustable and tuned for the demands of cross country racing.
• Racing Style and Ergonomics: The YZ125X carries the racing heritage of the YZ motocrosser with its aggressive styling from the front fender to the rear brake protector.

• GNCC-Tuned YZ125 Power: Based on the legendary 125cc liquid-cooled, reed-valve-inducted YZ two-stroke engine, the YZ125X utilizes a revised compression ratio, Yamaha Power Valve System (YPVS) timing and a model-specific CDI unit—all focused on creating broad power delivery that suits off-road terrain and a wide range of rider skill levels.
• Revised Power Valve: The YZ125X features the patented Yamaha Power Valve System—with broader opening timing compared to the motocross version for smoother power—to create a smooth balance of power across the rev range.
