Key Features

Features Gallery
  • alt

    Slim new bodywork

    The new YZ85 is equipped with dynamic new slimline bodywork inspired by the YZ125. New uniform and narrow radiator shrouds improve the rider control and give a more aggressive and balanced look.

  • alt

    Flatter seat and redesigned fuel tank

    A flatter seat and redesigned fuel tank provide improved ergonomics for easy front/rear weight shifting. The new seat design accommodates a new single bolt seat fixing, making routine maintenance easier and quicker.

  • alt

    New lightweight aluminium rear frame

    An all-new detachable aluminium rear frame replaces the previous model’s steel unit and reduces weight by 570gr, contributing towards the bike’s mass centralisation.

  • alt

    New balanced rigidity aluminium swingarm

    The new YZ85 is equipped with a redesigned aluminium swingarm featuring a revised rigidity balance, that improves chassis stability and allows for enhanced traction.

  • alt

    85cc liquid cooled 2-stroke engine with YPVS

    The 85cc liquid cooled engine features the Yamaha Power Valve System (YPVS) that boosts overall performance and contributes towards the bike’s easy to use torque. Running with a high compression ratio – and equipped with a close ratio 6-speed transmission – the YZ85 delivers outstanding acceleration with race winning power.

  • alt

    Improved high-efficiency air intake system

    The air intake system has been redesigned and features new sidepanels with large rear facing vents for a straighter airflow into the engine’s airbox, which, increases the intake efficiency for improved engine performance.

  • alt

    Fully adjustable 36mm KYB® upside down front forks

    Featuring specially machined one-piece tapered outer tubes to align them well with the rigidity balance of the frame, and equipped with 36mm inner tubes, the inverted front forks provide optimized damping settings. Combined with the fully adjustable low friction cartridge forks, the YZ85 has the most sophisticated front fork design ever used on a youth YZ motocross bike.

  • alt

    Link-type Monocross rear suspension

    Like the front forks, the Monocross rear suspension is directly descended from the advanced technology used on our factory race bikes. The new aluminum swingarm activates the progressive link-type Monocross suspension to give 287mm of rear wheel travel, that can handle everything from washboard sections through to hard landings.

  • alt

    Wave discs and new rear brake system

    For powerful and controllable braking the YZ85 features self-cleaning wave type discs – with a 220mm front and 190mm rear. And for more linear rear braking and improved feel there’s a new rear master cylinder with a built-in sub-reservoir.
