AER Air Piston Update

The 17.5 AER Fork received an update to the Air piston. We have found these to feel better with less friction after they are torn down and greased. The OEM grease is not sufficient and is grabby in the beginning of the range. We are updating all the older forks with this piston and the better grease. This is a great fork and a good design but needs some attention. Send us your fork and we can get you updated with the new piston and re-valve at the same time.

A48R with Shock Huck Valve Expert setup

We now have a dozens of rides on the latest version of the MX-Tech shock huck valve with AER fork on our 2016 KTM450SXF.

This mod is intended on running it in conjunction with the PC complete linkage, TANK, Triple Adjuster, and 5.2kg/mm spring. 195lbs Vet expert moto/gp settings.

First impression is huge improvement of bottoming resistance over revalved shock. I used to have a good amount of rub marks on the fender after a long moto and now I am just noticing the dirt is just getting rubbed off and no tire mark. The presents of the bottoming system is there and you can feel it but as long as your compression clicker isn’t backed out to far you don’t feel it come on too much when it’s low in the stroke.

Watching the action of the rear end of the bike looks so much different than a stock setup bike. Much more controlled motion and planted feel. Traction is greatly improved as you don’t need a really stiff low speed compression stack to compensate for bottoming resistance.

With the triple adjuster you can really dial in the low speed rebound to keep the back tire biting when unloaded on entry of a low speed roller into a turn.

Seat bounce any jump face out of a turn with confidence that you won’t blow through the entire stroke instantly.

The balance of the bike has improved to match the bottoming resistance of the AER Fork. While we are happy with the results so far we aren’t done tuning yet and will continue with races as weather is permiting. Stay tuned!

WP AER Midvalve Leaf spring mid valve and plastic piston replacement

2017 KTM and Husky models fitted with the AER Fork contain a solid clamp mid valve or a wave washer mid valve.  Along with having tuning constraints they are prone to failure and WP updated the new models to a sintered piston. We have a fix the Aer leaf spring with mid valve piston will also give the fork a much better feel. It is highly tuneable and durable.
