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.
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.
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.
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.
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.
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.
