UP 3 Way Damper Upgrade

FAST Suspension  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.

Customer Reviews

"Fantastic upgrade to my Yari, I get much better small bump sensitivity and less dive than with the original MoCo damper, There's tons of adjustment available with the 27 clicks on each of the slow and medium compression dials . It's super easy to install, the video is in French but still makes sense. The bleed port needs a Magura bleed nipple - I got one for £3 on ebay. "

"Game changer. Turned an uncomfortable Yari that barely used 3/4s if it's travel and spiked badly into a smooth plush fork with a ridiculous amount of grip now being generated. Wish I'd done it sooner. "

"Proper lols with that one Ash :-)! Ruth @TFT"
"I really didn't get on with the Yari before fitting the Yariup. It was relatively easy to fit the new damper, although the instruction video is in French its still relatively easy to do if you've taken a fork a part before. I used a 350ml syringe with a 6mm magura fitting in the end for the oil bleed. It was also easy to set up and get it feeling good. I've gone from a fork that blew uncontrollably through its travel, generally wallowing about, but somehow never using the full travel, to one that is nice and plush, sits high in the travel, has great small bump and in general works well. (That's the best I can describe it). It's a great upgrade, i wish i had done it sooner. "

"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"
