Actually, it gives a decent very short history of inline-6 bikes.

I'm going to start saving this week for one of those. Gotta have one when BMW gets them in production.

I got intrigued about the history of inline-6 bikes and here is what I found along with enough links to get you going:

Vintage - Size - Manufacturer/Model - Link
1957-1958 500cc MV Agusta 6-Cylinder http://en.wikipedia.org/wiki/Mv_agusta
1964 250cc Honda 3RC164 http://www.cyclechaos.com/wiki/Honda_3RC164
1965 250cc Honda RC165 http://www.cyclechaos.com/wiki/Honda_RC165
1966 250cc Honda RC166 http://www.cyclechaos.com/wiki/Honda_RC166
1972-1975 750cc Benelli 750 Sei http://en.wikipedia.org/wiki/Benelli_750_Sei
1977-1978 900cc Benelli 900 Sei as above

1979-1982 1047 cc Honda CBX http://en.wikipedia.org/wiki/Honda_CBX

I haven't paid much attention to bikes for sometime. There is one inline-6 not mentioned, the Suzuki. IIRC there were several models.

I searched the web for several minutes and I can't find where Suzuki ever had an inline-6 in the past but they do have a prototype which I didn't know:

Apparently I can't go back and amend my original post so here is a corrected list of inline-six bikes:
