I'll second what Griz said ... the Hyperpro springs and oil might not be as good as the other alternatives, but it simple, reliable, and very cost effective. They also make a huge difference.

Funny statement since teh KYB's are probably one of the best forks made for serious off road dirt bikes. They come on a all sorts of bikes that ride far better than the BMW off road.

thanks guys, at 165 lbs, I think I'll go for the springs instead.

I'd like to have gone for the Bitubo kit but if it's going to tank on me after a couple of years, the hassle of removing the cartridge and shipping it to the US and having to deal with cross border paperwork isn't worth it for me.

I'd do like the Traxxion kit just because I know they do good work, but I can't afford to be without the use of the bike, since at the moment, it's the only bike in the stable..

So,... hyperpro springs it is.. Now, I need a link to how to install them, I think I saw one on here. If you have it bookmarked, please post it.

Thanks for your input

The stock units hydrolock causing the harshness. Or so I have been told. Couple that with weak springs and, well, you know what you have.
My local suspension shop "Works Enduro Rider" looked at the stock units and bluntly said they were the worst design he has seen, "they would have better off throwing in a set of KYB's or Showas in there". That being said, the Bitubos will take your ride way beyond stock in a positive direction. In fact a comparo of the R/T units to the Bitubos it was so close, my friend who has the R/T's and I both agreed, for the $ the Bitubos get the nod. The catch is longevity. Mine went in 11 months and about 10k miles. Most of those on dirt roads, so they did see a lot of action. They are relitively inexpensive. $600, I paid $500 in fact. For double that price you can go to the Traxxion units which are still being tweaked to perfection. For 3 times as much you can go to Race Tech. My good freind, like I said, has these currently. They action is good. Not perfect. But close, according to RV8Pilot my friend.
Indy Unlimited has had the Traxxion units and made recomendations to Traxxion to impliment on my cartdriges which are being built any day now. Mostly ease up on the high speed damening. They have been very receptive to making these changes.

The least expensive is the Hyper Pro spring and stock units and guys seem to be satisfied as well. But that all hinges on how you ride and what your expectations are.
Not an easy choice.

Hi Dockingpilot,

First of all. Thanks for all the ground work. Its been a big help.

I too went the Bitubo route and am happy with them for my needs.
Have you checked to see if they can be rebuilt? I though I read in the
instructions something about a interval for factory service. If I could
do that as winter maintance, I might go that route.

Also, I think there's some install stuff in the "poor suspension" thread:

Bitubo with .55kg springs. I installed them and prefer them over the .60kg that come with the kit.

Not recommended for anyone over 220# geared up or rides the bike like a motocross bike, as you will likely bottom them out. I tried and got close. They definitely deliver a plusher feel. I do get more fork dive on hard braking.

Unless you can get the Bitubo's with lighter springs you are approaching Traxxion cost, so keep that in mind.

My last spring combo was with the Hyperpro spring installed. It felt pretty much like the .60kg spring off road. After linking several 400 mile pavement days back to back, the constant feedback of all the road imperfections convinced me to look for something softer. Anyone wanting a set of Hyperpro's PM me.

just seemed like you were saying the KYBs were only a little better. Maybe I misunderstood.

I'm just curious if you tore down those Btiubo cartridges to check what failed. (And if you could identify the method of gas charging them more than anything else.) I've been happy with mine after 10k miles but would like to be able to change out the oil.

Hey Bayner,
Traxxion sent them back to me and they are downstairs. They said the seals leaked. They are a delaer for Bitubo as well. But I do not know how you would go about servicing them.

Nah, I didnt even bother. I couldnt afford to have them leak on me when Im 3k miles from home. And the Traxxion Offroad AK-20's are just, just unbelievable. "Plush" is the word here.

So you really like the Traxxion cartridges? I was about to pull the trigger and get my forks sent to Georgia to Traxxion to have them done and my source, Aftershocks, kind of imploded. They're no longer affiliated with the local BMW dealer and will probably resume business at some point, but Phil is taking a vacation to clear his head and plan his future. Which sucks, because he has a good rep at suspension work and has done quite a few F800GS bikes...

The new offroad spec AK-20's are very plush. Way more than the Bitubos and makes the oem cartridges feel like wood. Martin was the fella who built my AK-20's at Traxxion.

Cost?

Hey Frank,
Glad to hear you got you fork problem solved.
If you don't mind me asking how much were the AK-20s?
Did it change the height of the front end?
Did you talk to them about their options for the rear shock?

Your trip is getting closer...can you taste it yet?
