Krauser MKM 1000 BMW out there?

Hello everybody,

I am new in this forum, my name is Dirk.
I am wondering if there are any Krauser Owners
out there. Around 15 frames of this type should be in US.
I am interested in fotos, parts, complete machines and contact.

See my Krauser on www.r73.de, you find my email there as well.

Best regards

Dirk

I'm moving this to Airheads, but I know two guys back east that have, between them, 4 of the US MKM 1000s.

Thanks Dave for moving it to the right place!
Would be interested in the emails of those two Krauser contacts.

There's one at a place called Gold Coast BMW in Long Island, and another at Lone Star Texas motorcycle museum.

I remember lusting after one of these as a kid and writing to I think Slater Brothers re Magni Frame Kits for a BMW. I wonder now with all the great cad cam and 3d Image modelling stuff that you could reverse engineer the frame and get all the dimensions and angles and re make the frame. Yes I know there is some glass fairings but I image most people would want the handling first?

The specs you posted are exactly the same as all 1976-84 R100RS and RT bikes, stock from the factory, except the stock compression ratio was 9.5:1

The Krauser was NOT a speed demon. It was a handling dream though. The best thing about it was the frame, but back in the day, the cost was very high. You could modify and stiffen the stock R100 frame to attain the same effect, for a whole lot less. The 4 valves per cylinder added a mess of complexity with very little gain in performance. Plus, the broke pretty easily.

wonder if Krauser compression was same as RS at 9.5:1 .. a typo at 8.2:1

Krauser 4 valve heads sure have a reputation of bad reliability. did factory setup Krauser bikes also share that same trait?

Hello!

The compression with Krauser heads and pistons was 10.2:1.
Factory setup Krauser engines were in no way different.

Best regards

Rob, thanks for the link, I missed that auction.

Adrenal, thanks, I seen this more than a year ago, no reaction via email.

Darryl, dont know that person, sent you a personal email to follow this up.

All, thank for your comments and interest!

There were two factory Krauser models, 2V and 4V. The 2V is the original
BMW engine, the 4V is the same, but with the 4V Krauser heads.

Dirk
