YZ85LW
Yamaha YZ85LW for Sale at Moorooka Yamaha in Moorooka, QLD | Specifications and Review Information
For 2022, 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 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 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 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.
Availability from early 2022.
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.
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.
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.
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.
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.
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.
