Airhead cartridge fork system

[DrAlf]

These things seem excessively expensive and probably unnecessary which of course means I want a set - obviously.

Is anyone running a set? Any feedback? Ultimate airhead bling?

Have you looked at emulators and new springs? https://www.brooksuspension.co.uk/fork-internals/yss/yss-fork-emulators

I had to laugh about the bit in the explanation that said “On some older model vintage bikes (1960s and 70s) many forks did not come with a piston ring”……..er that’ll be just like all the GS paralever forks up to 1996 then

You could get a set of WP USDs and yokes for that price …

I've had RaceTech springs and emulators fitted on four bikes now and they're a really good step up in damping / ride quality for the price.

I take it you're in the states Joe? I think P&P would make it to difficult to use RaceTech from the UK. Do we have a UK version of RaceTech - Maxton maybe?

No, I'm in the UK. PDQ did the first two bikes I had done - https://pdq1.com/ and Ryan at ShockTech did the last two for me - https://www.shocktech.co.uk/

Emulators are not hard to fit if you are a competent mechanic. https://www.wemoto.com/components/forkparts/yssforkvalves or have a look on youtube.

Springs various suppliers. I used progressive ones from Motobins.

Glyn Robinson, of Sports Motorcycles (& Steve Wynne's go to engineer) has a 'Sports Valve' kit available for various 1970 - 90s Ducati twins, both bevel and early belt drives. This allows for external adjustment of compression and rebound damping, easily done with a tool that is supplied in the kit. Aimed at race bikes he's also working on a version for BMW bikes, including road bikes.
I bought a kit for an old Ducati a few years back and suggested at the time that a version for the GS would be welcomed - no idea if that's in the pipeline
I think a prototype's already been tested on the track and a road version MAY even be production ready (but website does not reflect this).
