Well the guys I talk to regularly are Bas who runs the Alphen service centre (biggest service / sales centre globally) and Pieter who owns the company and runs the R&D in Werkendam. Their logic is quite different. Because many BMW bikes run 45mm Marzocchi fork derivatives, and yet have very low quality forks, developing inserts is easy and a solution that can fit many bikes at the same time. You can have very slightly different valving but the same machining and make it fit the F800, F650, HP2, X-challenge, X-Country, X moto etc. They all run 45mm Marzocchi forks, and they are all crap. They all need a single simple valving solution to make them work properly. Those forks are not different sizes, they are all the same size. I can list 20 other bikes out there that run the 45mm Marzocchi manufactured forks if you like, They are the same size as well. So not sure what you mean when you say the guys told you the forks are all individual sizes ?

The downside with any inserts is that they are limited by the forks themselves. In the case of the BMW marzocchis, a limiting factor is that usually one fork does rebound damping and one fork does compression damping. An insert cannot change that, and you will never be able to get full compression and rebound damping in both forks, so it will never be as good as full fork transplant, but will be a lot cheaper.

But the reality is there are many projects Hyperpro are working on, and unless there is pressure from consumers, projects can and do slip onto the backburner. So again I say, if you have an interest, contact them so they know there is pressing demand. Otherwise the product may very well not be developed.

I was in Werkendam, but good to know that they are "secretly" looking at producing something which will make the F8GS better...

I might contact them later this year.

Thanks.

I've just been re reading this thread, as I'm financially in a position to get this done now!

I'm definitely going for the fully adjustable rear from Hyperpro, but I'm still unsure whether whether to just go for the replacement Hperpro front fork springs OR to spend a little more and go for a full replacement? Does anyone know whether Hperpro's 'work' on aftermarket fork products has got anywhere? Does anyone have any other suggestions?

I'm not looking to hoon around off road, I just don't want to be limited in my exploring!
