The YZ85LW (Large Wheel) model takes the race-winning YZ85 formula and enhances off-road capability even more with the addition of a larger 19-inch front wheel and 16-inch rear wheel wrapped in high performance Dunlop MX3S tyres.

Along with its proven liquid-cooled YPVS-equipped 85cc powerplant, fully adjustable suspension and large diameter brakes, the YZ85LW boasts numerous enhancements to expand its overall performance.

Rider ergonomics have been improved by way of a narrower tank design, flatter seat, side covers and slimmer, symmetrical radiator shrouds. This enables greater freedom of movement for smooth shifting of body weight and better machine control.

For demanding junior racers, the YZ85LW has been enhanced in several key chassis areas to optimise strength and rigidity, including revisions to the main frame, longer swingarm and rear wheel axle. The aluminium swingarm was redesigned to enhance balance between longitudinal and torsional rigidity for improved handling stability. A removable rear subframe constructed from lightweight, high-strength aluminium reduces weight. The rear brake master cylinder now has a built-in sub-reservoir providing more linear brake response and increased control.

  • 85cc liquid-cooled, two-stroke engine
  • Yamaha Power Valve System (YPVS) for broad tractable power across the rev range, without losing peak power at high rpm
  • Lightweight aluminium rear frame
  • Improved rider ergonomics
  • Fully adjustable front forks
  • Improved air intake
  • New rear brake system
YPVS 2-stroke engine

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.

Lightweight aluminium rear frame

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

Improved rider ergonomics

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.

Fully adjustable 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 optimised 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.

Improved air intake

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

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.
