Yamaha has been building championship winning 2-stroke motocross bikes for 50 years. Along the way we've won just about every title worth winning. The latest YZ85 comes with the same advanced race-bred technology that goes into the company's adult motocross machines and is ready to power you into the victorYZone.
Victory: Never given, always earned.
Many of today’s pro riders started their careers on the YZ85. And when you take a look at what this bike has to offer you can see why. Its high performance 85cc liquid-cooled 2-stroke engine is equipped with Yamaha’s race-bred YPVS that gives you holeshot-winning acceleration. And its adjustable suspension systems are built to master the toughest tracks.
The YZ85 also comes with a lightweight aluminium rear frame and aluminium swingarm, large diameter disc brakes and a high-efficiency air intake – just like the bigger YZ125. For maximum rider control there’s a flat seat, slim body and an ergonomic fuel tank. And with the updated Icon Blue colourway and new graphics completing the looks, the YZ85 is ready to power you to the next level.
Features
Slim bodywork
The YZ85 is equipped with dynamic slimline bodywork inspired by the YZ125. Uniform and narrow radiator shrouds give an aggressive and balanced look that underlines the YZ85's winning heritage.
Flat seat and ergonomic fuel tank
A flat seat and ergonomic fuel tank allow for easy front/rear weight shifting for optimum control. The seat design accommodates a single bolt seat fixing, making routine maintenance easy and quick.
Lightweight aluminium rear subframe
A detachable aluminium rear subframe helps to keep the YZ85's weight to a minimum and also contributes towards the bike's lightweight agility by centralising mass.
Aluminium swingarm
The YZ85 is equipped with an aluminium swingarm featuring a finely tuned rigidity balance that contributes towards chassis stability and helps to achieve high levels of rear wheel traction.
85cc liquid cooled 2-stroke engine with YPVS
The 85cc liquid cooled engine benefits from 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.
High-efficiency air intake system
The air intake system incorporates side panels with large rear facing vents that are specifically designed to give a straight airflow into the engine's airbox for high levels of intake efficiency and improved engine performance.
Fully adjustable 36mm KYB upside down front forks
Featuring specially machined one-piece tapered outer tubes to match the rigidity balance of the frame – and equipped with 36mm inner tubes – the upside down KYB front forks provide optimised damping settings. Combined with the fully adjustable low friction cartridge design, the YZ85 has the most sophisticated front fork design ever used on a youth YZ motocross bike.
Link-type Monocross rear suspension
Like the front forks, the Monocross rear suspension is directly descended from the advanced technology used on Yamaha's factory race bikes. The aluminium swingarm activates the progressive link-type Monocross suspension to give 287 mm of rear wheel travel, that can handle everything from washboard sections through to hard landings.
Self-cleaning wave discs
For powerful and controllable braking the YZ85 features self-cleaning wave type discs – with a 220mm front and 190mm rear. And for linear rear braking and plenty of feel there's a one-piece rear master cylinder with a built-in sub-reservoir.
