The 2025 Yamaha YZ125 stands as a testament to Yamaha's commitment to delivering high-performance motocross machines. Designed for both seasoned racers and those stepping up from smaller classes, the 2025 Yamaha YZ125 combines advanced engineering with rider-centric features to offer an unparalleled riding experience.
Powerful Two-Stroke Engine
At the heart of the 2025 Yamaha YZ125 lies a liquid-cooled 125cc two-stroke engine. This power plant delivers impressive acceleration and a thrilling mid- to high-rpm range, ensuring riders have the performance needed to tackle competitive tracks. The inclusion of Yamaha's patented Power Valve System (YPVS™) enhances bottom-end acceleration while maintaining strong mid-range and top-end power. This system ensures a broad and usable power band, catering to various riding styles and track conditions.
Precision Fueling and Ignition
The 2025 Yamaha YZ125 features a high-precision Hitachi Astemo® Keihin PWK38S carburetor equipped with a power jet and throttle position sensor. This setup, combined with a 3D-map-controlled CDI unit, ensures precise ignition timing. The result is crisp throttle response, superior rideability, and excellent over-rev characteristics, allowing riders to push the limits with confidence.
Advanced Chassis and Suspension
Constructed with a race-proven aluminum semi-double cradle frame, the 2025 Yamaha YZ125 offers the perfect balance of strength and flexibility. This design provides stability during high-speed straights and agility in tight corners. The removable aluminum rear subframe, made from square-section tubing, reduces weight and simplifies maintenance.
The suspension system is highlighted by a fully adjustable 48mm inverted KYB® front fork featuring the Speed Sensitive System. For 2025, Yamaha has introduced a hand-adjustable knob, allowing riders to make quick, toolless compression adjustments on the fly. The rear suspension utilizes a fully adjustable KYB® shock with reduced-friction Kashima Coat™ internals, offering 12.4 inches of travel for exceptional rear wheel control and comfort.
High-Performance Braking System
The 2025 Yamaha YZ125 comes equipped with a high-performance braking system featuring a 270mm front rotor and a 240mm rear rotor. The large front pistons and rigid calipers provide exceptional braking power and feel, giving riders the confidence to push harder into corners and navigate challenging sections with precision.
Rider-Centric Ergonomics
Yamaha has meticulously designed the 2025 Yamaha YZ125's ergonomics to enhance rider comfort and control. The bike features a flatter seat, a narrow fuel tank, and seamlessly integrated body panels, allowing for greater freedom of movement. This design enables riders to easily shift their body weight, optimizing control during aggressive maneuvers. Additionally, the slim shroud width further facilitates easy movement, ensuring that the bike feels like a natural extension of the rider.
Aggressive YZ Styling
Aesthetically, the 2025 Yamaha YZ125 exudes a fierce and competitive aura. The aggressive bodywork includes slim panels and blacked-out radiator shrouds, complemented by a bold graphics scheme that highlights Yamaha's racing pedigree. Premium graphics are embedded into the bodywork, ensuring durability and resistance to scratches, keeping the bike looking fresh race after race.
Race-Ready Features
The 2025 Yamaha YZ125 comes equipped with several features aimed at providing a competitive edge right out of the crate. An aluminum handlebar with a two-position adjustable clamp allows riders to customize their handlebar position for optimal comfort and control. The new water-resistant PVC handlebar pad adds an extra layer of protection against the elements. Wide foot pegs offer enhanced grip and stability, while the gripper seat ensures the rider remains securely positioned during intense riding sessions.
