Bike Setup Yamaha YZ85 LW / SW

Make:  Yamaha

Model: YZ85 LW SW

Relevant Years: 2018 - 2023

Oem Trim / Test notes:  A much improved bike over the years but still it is missing key internal components to compete against the orange brigade. 

Our setup kit for this bike addresses these issues. In the fork we add in a hydraulic bottoming system for better control on heavy landings and deep in the stroke.  This addition is already in all the senior YZ/YZF range as oem, it is a must add into the YZ85 system that only runs old technology in hard bottom out rubbers.  Alongside this in the fork much finer tolerance spring guides are fitted to guide the system smoothly throughout the action.  Improved flow pistons and valving setting result in a super smooth KYB fork much like its older bros in the YZF / YZ range. 

In the rear end we address the loose acting rebound action and set the compression to match each rider speed and bike LW/SW.  less compression spike with more rebound control.
