Product Description

FAST Yari'UP! 3 Way Yari Damper Upgrade

This is a plug and play compression assembly for the Yari, REV RC ‘18MY + and Boxxer RC from Fast Suspension. The kit provides external adjustment of low and mid speed compression and an internal shim stack for high speed. It turns the damper into a closed circuit with no emulsion for more accurate, low fade damping performance. Winner.

Here's what FAST say:

The performance without compromise, we started from the observation that with a setting High Speed / Low Speed, we found only a compromise.
  At Fast Suspension, it is not possible !!!
That's why we created Yari'UP!
Step 1: We must first distinguish the 3 phases of compression.
Low speed: comfort at low speed, grip
Mid speed: limit the dive to braking. For better control of the bike.
High speeds: Impact management for more comfort.
Step 2: The product
We have managed to integrate these 3 distinct compression phases in our Kit!
No more compromises , just pure performance !!
