    Most powerful YZ125 engine

    The high-tech 125cc 2-stroke engine is the most powerful unit ever used on the YZ125. Equipped with Yamaha’s famous YPVS that gives instant response and excellent useability across the rpm range – and featuring lightweight race-bred internals – it’s destined to take you to the victorYZone!

    Ultra-slim bodywork

    The athletic bodywork is ultra-slim, with the area between the rider’s knees the narrowest kit’s ever been on a YZ125 – and this athletic and modern body design underlines the bike’s lightness and compactness. These slim dimensions give a high level of rider mobility and reinforce this lightweight racer’s feeling of agility.

    Keihin Powerjet carburettor

    The YZ125 is equipped with a Keihin PWK 38.1mm carburettor featuring a solenoid controlled Powerjet that instantly delivers its fuel/air mix for even more explosive performance, giving a real advantage out of the gate and when accelerating hard out of corners. A TPS (Throttle Position Sensor) and 3D map controlled CDI ensure optimized ignition timing, while the V-Force reed valve assembly ensures optimum intake efficiency at all engine speeds.

    Smooth shifting 6-speed transmission

    Every second counts and for reduced lap times the YZ125 runs with a super-smooth shifting 6-speed transmission that enables you to accelerate efficiently and stay out in front. Transmission ratios have been carefully chosen by Yamaha’s engineers to maximize race performance and power output in all conditions.

    High efficiency air intake

    The complete intake system has been developed to provide the smoothest possible flow of air into the 38.1mm carburettor for a high level of engine efficiency. Components including the seat base, rear frame and sidepanels are all designed to reduce air resistance for stronger and more useable power output.

    Race-developed ergonomics

    Engine performance is just one element of being competitive – the ability to handle the power effectively and take total control of the chassis is also vital. A flat seat with a low front combined with a slim tank and narrow radiator shrouds make it easy to shift your weight around the bike for increased controllability when braking, accelerating and cornering.

    Best-in-class KYB suspension

    Yamaha’s SSS (Speed Sensitive System) KYB front forks are widely regarded as being amongst the best designs available on a production motocross bike. With idealized low speed damping settings on both the front and rear suspension systems, the YZ125 delivers class-leading handling and excellent traction.

  • alt

    Powerful braking system

    The brakes on the YZ125 have been developed to handle the engine’s high performance. The 270mm diameter front disc and 240mm diameter rear disc are equipped with big-piston calipers that produce effective and controllable stopping power.

  • alt

    Single bolt seat fixing

    A single bolt seat fixing gives quick and easy maintenance, and the design of the aluminium rear frame is also contributing towards intake efficiency by enabling a smooth flow of fresh air into the airbox.

  • alt

    Duo-tone colours and new graphics

    The YZ125’s duo-tone colour scheme features a contrasting Icon Blue and dark blue design with blue wheels giving the bike a dynamic new look that perfectly complements the in-mould graphics and slimline bodywork.
