Is this the 2WD CJ bike? Awesome!
I loaded up my gear and headed off to do some riding in Arizona.
But about 20 minutes away I had one of those "wonder where that goes" moments. Ended up on miles of two track and no company
landing me here- I had no idea where here was-best way to adventure.
Rode for miles and then had big problems with my vision :eek1 , I couldnt see going anywhere when the weather is still great here and I can play in my own back yard- save vacation for later enjoy it here for now. So today I loaded up with my fly fishing gear and headed out -
A little icy on the trails over 10,000'
all in all good day to be out on the 990.
Yes, this is the "AWD" bike.
A little front wheel roost to confirm it's working.
Long time lurker hopefully pulling the trigger on an "R" this new year... anyways, I found this and thought you might enjoy it. I don't read German but dang this thing looks bitchin!...
sorry for the diversion... now back to torturing me with your rides until I get mine...
I promise this is the last one...

Wow!! Congrats!! You are an awesome engineer!!!
Just a question, is not easier to install an hidraulic system? A pump in the engine and a motor in the wheel?
Already been done by yamaha/Bosch-Rexroth . One to one pump to hub, some how this is kept under grips with B-R and it is near impossible to get the exact hydraulic parts needed. I have looked into this and have a guy working on Bosch trying to get this together but its been pretty slow: well, really at a stand still. They did this years ago and there really was not much talk about it. I believe Ohlins was involved heavy with this also. Im sure someone here will come on and correct me if I am wrong. The issue with off the shelf units that you can source easily and affordably is that they are heavy and generally low speed high torque. We want high speed and super light.
Didnt KTM do an elec unit? Starter/generator n elec motor front hub?
Took the SE out to test the new Renazco seat, yes it is definitely a huge improvement over my other custom seat!
I have Yamaha 2trac with hydraulic front drive and i was able to buy the whole hydraulic system for 8000E spare part. You need also the front hub and spokes as they are custom. The kit adds 8 kg to the bike, 5 of which are in the front wheel. I can give you all the info from the hydraulic motors if you need it.
Went for a little ride just south of Lake Tahoe. Weather and soil conditions were perfect.
That looks like it was a very fun day.
More like too much time on my hands.....

All I can say is it's been holding up great and it helps a ton.
It may have been easier, but at the time, the only way I could get hydro parts was to buy an entire 2-track bike, no way. So I used what I could get and what I knew. Biggest PLUS, is I can get parts, if need be, in the USA.
When doing research for this build over 4 yrs ago. Here were my thoughts:
-If they hydo worked so well, and was so much better, why is it not around today? (4 yrs later - Still not so)
-As for KTM AWD/2wd- They have a patent on an Electric version, that as far as I know has never seen the light of day. The only AWD KTMs I have found other than the Christini System was an Ohlins Hydro conversion - Like the Yamaha.
-If it was that good, Why are the Erztberg racers using Christini on there KTMs and not the Hydro? (4 yrs later - Still Mechanical drive is used, NOT Hydro)
- When I asked KTM about there AWD future, I got no reply, but they did say my bike was an interesting concept.
40,000 miles later, I'm still glad I spent the time to build it.
Action shots soon to follow
