Talk:Motorcycle frame

message: Would discussion of engine mounting belong in this article? Is the engine a structural member of the frame? Is the engine rigidly mounted? Etc. -AndrewDressel (talk) 14:38, 24 June 2008 (UTC)

thread_title: PHOTOS PLEASE

message: This article is in dire need of a general statement about motorcycle frames and some definitions of frame components. For example, what is a cradle?  A spine?  A downtube?  People come to encyclopaedias to be informed, not to be further confused! Sincerely, SamBlob (talk) 19:30, 12 February 2010 (UTC)

message: There is no description of a "diamond" frame.  I thought a diamond frame was essentially the standard pedal cycle (push-bike) frame that was the examplar for the very earliest motorcycles.  Does the "diamond frame" have any  meaning for modern motorcycles?  If so, it should be added, and if not, perhaps the section should be excised. Arrivisto (talk) 14:03, 26 May 2013 (UTC)
replies: text: I think the diamond type was more common in the past but the term is still used .<P>Part of the problem with this article now is we have two orthogonal sections: material and type. We should have three aspects: material, construction, and shape. So you can have a frame with pressed steel construction, but the shape could be a single spine or underbone (Super Cub, Ducati Piuma), or pressed steel monocoque (Vespa). The Super Cub and the Sport Cub both had a single spine frame, but the U-shaped Super Cub had a step-through feature, while the other was T-shaped and had to be straddled; the difference in shape here is significant. You can have welded tube construction, like the Ducati trellis frames, or you can have the cheaper method of tubes joined with pressed steel gussets.<P>Ofen when you read sources desribing a motorcycle's frame, they will only mention the aspect that the author thinks is most significant, like material (aluminum, carbon fiber), construction method (pressed, extruded box sections) or shape (full cradle, spine), but they won't mention all three dimensions. We should acknowledge this ambiguity in our sources. --Dennis Bratland (talk) 23:05, 27 May 2013 (UTC)
thread_title:  Diamond Frame? 

message: The definitions of these two types seem to suggest that Perimeter & Beam frames are basically the same.  If they are indeed different, perhaps the definitions should be amended to make this clear.  Arrivisto (talk) 18:25, 29 May 2013 (UTC)
replies: text: I have made an edit to make beam & perimeter frames adjacent in the list. Arrivisto (talk) 16:57, 22 July 2013 (UTC)

message: I'm not convinced the CG125 is a good example of the type.  The photo (File:Honda CG125 orange.jpg) seems to show the front downtube terminate at the forward engine mount, without any  under-engine "cradle".  Arrivisto (talk) 17:01, 22 July 2013 (UTC)

message: As per above comments, there should be more pictures (and schematic drawings I'd say) and more frame types covered, like the mentioned diamond frame (and other older types shared with bicycles). The nicely written Bicycle frame article could be taken as a good example... --Arny (talk) 20:49, 8 March 2018 (UTC)
