KroozR KYB Mid Post Float Kit

KroozR KYB SSS 29mm Fork Cartridge Float Tunable Posts for 2021-on Yamaha YZF Models

All new 2022 design.

The all new 29mm cartridges from Kayaba are nearly all fitted with a more solid trampoline-style midvalve. This offers great hold up but we find it sacrifices too much initial plushness for most riders.

As this all new trampoline-style mid valve setup contains many more individual shims than this float post we find a setting easily arranged from the factory shims in the standard midvalve.

Kit Includes:

Post Assembly
Light Mid Spring
Custom Nut and Top Plate Washer

For example only our most common mid valve shim arrangement stack to achieve common float of .25 - .3mm as below to fit our post:

Piston
21.12/4
18.12
16.12
14.12
12.12
10.2/2
12.15/1
12.3/4 (spacer shims only)
