Hello K-Bike Fans,
I have just published a comprehensive user guide to swapping the standard K1100, K100 16v and K1 wheels to those from the K1200 (K589 and K41) models:
Wheel Conversion – kwankenstein.org
Please let me know if you find it useful.
My guide builds on the work published by the author of this German-language site: http://www.k1100rr.de/ which describes a method for converting the front-end that retains the original axle (and therefore the intended strength and stiffness) by replacing the wheel bearings. I believe that it‘s an excellent solution. Indeed, I described the conversion to my local vehicle inspector (TÜV here in Germany) and - following a satisfactory test ride - the changes were approved for use. Since then I have completed over 2000 km with no issues.
All the best,
Adrian.
