Touratech has excellent holder for the 2610 but to my understanding no parts to attach the holder
on the handlebar of a naked K100. Anyone done this ? There are some suppliers for RS and LT models
where 2610 holder is mounted utilizing the fairing or screen screws but that does not work with my naked K100.

All ideas, suggestions and help is appreciated.

I really like the Ram Mount Systems. Have a look on ebay...

Before buying on Ebay Check this: Ram Mount This is for a K75rt as their choice goes only as old as 1991 for the motorcycle.
There is not difference between a K100 and a K75. If your bike is a naked one, you may have more choice. The cost is only $41.00
