As an important entry into the world of competitive motocross, the YZ85 has long been the mini race bike of choice for future champions. Light, nimble and fun with a top shelf suspension, it serves up big-bike spec in a small bike package.
Along with its proven liquid-cooled YPVS-equipped 85cc powerplant, fully adjustable suspension and large diameter brakes, the new 2022 YZ85 boasts numerous enhancements to expand its overall performance.
Rider ergonomics have been improved by way of a new, narrower tank design, flatter seat, new 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 new YZ85 has been enhanced in several key chassis areas to optimise strength and rigidity, including revisions to the main frame, swingarm and rear wheel axle. The aluminium swingarm was redesigned to enhance balance between longitudinal and torsional rigidity for improved handling stability. A new 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.

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.
