YZ85/LW

Key Features

Features Gallery

    Sharp bodywork

    We figured than when you look good you feel good – and so we’ve kitted the YZ85 out in sharp bodywork that brings it in line with our adult motocross models. The package is completed with ‘factory bike’ style Speed Block graphics.

    Strong and useable engine performance

    The YZ85’s ultra-compact and lightweight 2-stroke engine is famous for its strong yet manageable power that enables new and more experienced youth riders to race to the very best of their ability. The YZ85 delivers useable performance via its close ratio 6-speed transmission.

    Upside down front forks

    The YZ85 features much of the technology first developed for our larger-capacity motocross bikes, and the upside down forks are a scaled down version of the advanced suspension used on the adult class YZ models. Featuring 36mm diameter inner tubes, these smooth-action forks give 275mm of wheel travel for excellent shock absorption.

    Monocross rear suspension

    Like the front forks, the rear suspension featured on the YZ85 is directly descended from the technology used on our factory racers. A long aluminium swingarm activates the progressive link-type Monocross suspension system to give 282mm (LW model 287mm) of wheel travel that’s designed to handle everything from washboard sections to hard landings.

    Available in large wheel (YZ85LW) option

    In order to accommodate riders of widely varying sizes in the youth class, this model is offered in two wheel size options. With a 17-inch front wheel and 14-inch rear wheel, the YZ85 is ideal for smaller riders, while the 19-inch front wheel and 16-inch rear wheel on the YZ85LW suits larger or older competitors.

    Large diameter disc brakes

    Races are often won or lost by the rider who can brake latest, and so we’ve equipped the YZ85 with powerful disc brakes that offer plenty of feel. At the front there’s a lightweight large diameter 220mm diameter disc slowed by a compact caliper, while the 190mm diameter rear disc gives accurate rear wheel control.
