Question Thinking about an airhead scrambler...

I've done some work on airheads, an R100/7, R100RS, R100GS and I want to build a turnburner from a monoshock or paralever.

I've got a line on several frames available.
One fella has a monoshock frame and swingarm already powder coated and ready to go. Never had one o them...I've read the where one of the best handling Beemers.

Hadn't really thought about using a monoshock frame, I was thinking R100GS or R100R frame, a 19" front wheel and maybe the K75 front end.

I want to spend some time bracing it up, get a nice rolling chassis together then source an engine later.

I'd appreciate some opinions and insight on what you guys might have to say about it all.

Think "scrambler"...

The only problem with using a Monoshock frame is tracking down a g/s bevel box and wheels. If you cannot find them then you are stuck with cast wheels which spoil the look.

I guess a twin shock would be the easiest option



or this one that appeared on UK Ebay

Nice looking bike, Rapid! I like!

I am curious why anyone would change to pod filters and leave the stock airbox attached. I'd think for dirt duty one would prefer the stock filter.

Rob, I agree, twin shock is probably the best way to go. I do like the looks of those tubeless wires though.

I thought the same. Strange thing to do.

I do like the chopped Paralever subframe look.

Hoping the bike in parts in my basement will look something like this eventually...something for cruising the dirt roads.

Yeah. Im not looking for major modifications. I ride a real dirtbike in the woods now, and have the RS for road duty. I just like the idea of an airhead for cruising backroads at 40-50. Not a big fan of the bar end turn signals, and I have a high pipe already. I just need to finish my boat project before I take up the space with the bike project...

i really like the high pipes but I can't figure out how to do this without it being very impractical. in that picture of the cool black scrambler, it looks like the pipe is right next to the fuel line. maybe it's the angle of the photo. I also wonder about it roasting your leg. really cool looking bike though.

By 'bevelbox', you mean the final drive?
I know where an R80 drive is available, along with the prepped R80 frame...

That's pretty much what I have in mind elmoreman, but more streetafied maybe, kind of ST-ish.
This totally works for me.


BTW, the pic firs post is not my bike, just a concept for reference.

www.gletter.de make repoduction parts for the ISDT bikes. Their exhausts tuck up behind the subframe. Drop them a line to see how much the pipes are.

Check out the HPN website for their offerings:
http://www.hpn.de/english/english.html
You will get plenty of ideas at least...
The HPN Sport is my ideas of a great airhead off-roader!



The benefit of the monoshock frame with the R1100 rear suspension
is that you can use 2 into 1 pipes exiting on the left of the frame,
allowing you to fit two full sized panniers.

I saw a Guy from Europe touring South Africa recently with a combo bike that was a great compromise:
A BMW R100 PD from the steering neck backwards and a KTM front end.

(I didn't get photos... )

I doubt it. The nipples on the cross spokes are fitted into the hub instead of the rim.
