Thanks for the replies. It does look like a Webber doesn't it? As far as the attachment goes... I had originally planned to attach to the two bolts at the front of the grab handles (or whatever they are properly called) and the back of seat hold down bolt. Just didn't work out. As I was not able to find anything better to attach to I made my own attachment holes.
It is a commuter bike - and a toy. I found that carrying a bunch of stuff in a back pack basically sucks. The S40 is a nice bike but it does not even have a document pouch under the seat. No place even to carry a pen.
On my first bike, a 1979 Honda Twinstar 185 I had 2 Montgomery Ward hard saddle bags which let me carry a reasonable amount of cargo. I traded it in on a 1981 CM400 custom and added 2 Krauser (made bags for BMW) LARGE saddle bags and never wanted for cargo space if and when I needed it. These days it is hard to find A) any motorcycle which does not look like a Harley wannabe B) hard saddle bags other than custom fit for Gold Wings, Electraglides and other 2 wheeled land barges. End of rant
As to my back, it would be bad before long if I lean on the "back rest pad" which JCW attached to their trunk. It is harder than the ABS of which the trunk is constructed.
