New 2019 V2 FAST Yari/Revelation UP 3 Way Damper Upgrade

FAST Suspension  New 2019 V2 FAST Yari/Revelation UP 3 Way Damper Upgrade

Product Description


FAST YariUP and RevUP 3 Way Compression Damper Upgrade.


This is a plug and play compression assembly for the Yari, and Revelation RC (35mm stanchion only) from Fast Suspension. The kit provides external adjustment of low and mid speed compression and a reconfigurable internal shim stack for high speed. 

Here's what FAST say:

Performance without compromise. 

By dividing compression events into just two phases, High Speed and Low Speed, there is inevitably a compromise.


That's why we created Yari'UP!

With the UP kit, we give you control of 3 distinct phases of compression:

Low speed: Comfort at low speed, grip

Mid speed: Limit brake dive. For better control of the bike.

High speeds: Impact management for more comfort.


No more compromises, just pure performance!!

This is a popular upgrade for E-Bikes, whose greater mass makes them more susceptible to brake dive. The stock Motion Control damper in the Yari and Revelation RC can struggle to control this without reducing small bump sensitivity and choking on larger impacts. With the UP damper, just dial in the mid-speed. Problem solved.

"yes, a good upgrade, before the upgrade the Yari fork was harsh and crashed through its stroke. with the Yari up damper fittrd I can keep the fork high in its stroke with no degrading of comfort. still some tuning to go to get the comfort I want"
