Yamaha has announced its race-winning YZ250F and YZ85 motocross models have received an overhaul for 2019, with both marking a new generation of race bikes, while the remainder of the range has been enhanced with a host of upgrades.

Heavily updated in 2018, The 2019 YZ450F returns to the line-up with several updates, including updated suspension settings, changes to the electric start system and more.

The 2019 YZ250F is fresh from the ground up, including an all-new engine, new frame, new bodywork and features never before seen in the 250cc class – such as smartphone tuning.

The YZ250F also boasts an electric starter system with ultra-lightweight lithium battery, enhanced cooling with larger and repositioned radiators and two-mode adjustable engine mapping.

The chassis has also been upgraded with a larger upper frame bracing to improve rigidity and durability, while a wider rear frame spars and all-new engine mounts centralise mass for the best possible balance of bump absorption, stiffness and feeling of grip. Complimenting the chassis changes is updated class-leading KYB suspension settings.

The 2019 YZ250F will hit Australian showrooms early August priced at $11,399, and it will be available in two colours: Team Yamaha Blue and White and Competition White.

The legendary YZ125 and YZ250 models return for 2019 to complete Yamaha’s lineup of two-stroke motocross bikes. Lightweight aluminium frames and patented YPVS-equipped (Yamaha Power Valve System), reed-valve inducted engines provide an incredible power-to-weight ratio while maintaining Yamaha’s excellent reliability and durability.

Both the YZ125 and YZ250 each receive the same industry leading KYB spring-type fork and KYB rear shock for unmatched handling on the track.

The first step on the bLU cRU ladder has been sensationally catered for by the recently released YZ65. Now riders moving up from that first step will be treated to an all new YZ85/LW.

Like the YZ250F, the 2019 junior motocross race model is all-new from the ground up, and the winning two-stroke is now fitted with Yamaha’s YPVS power valve system to improve performance. Plus many of the new YZ85 parts are interchangeable with the smaller YZ65, making the step up even less of a hassle.

Even though the outgoing model won the 2018 Australian junior national title, the new 2019 YZ85 is now fitted with a new engine complete with revised intake, exhaust and transmission. And new front forks, new swingarm, new wave-style brake rotors, adjustable ergonomics and more – ready to win races straight off the dealership floor.
