Creepinogie said:What factory?
Yes.
Ryno said:When did the factory stop using a rigid frame in favor of a swingarm?
Were they ever producing both rigids and swingarms together?
BarryW said:1957 was the last year for the rigid frame. 1958 was the duo glide frame.
Creepinogie said:But HD made swingarmed framed bikes before the duo-glide (1958).
K model, sportster, etc.
Creepinogie said:Might be. But not might be obvious to someone asking a basic question without details. Obviously HD was not the first to build either style frame. It'll be interesting to see what the next progression in frame technology will be. Softail was really a step backwords.
JiveBomber said:I think the Sportsters- First called the "K" models got the swinging arm in 1952 when they debued...
How bout KR?? Here's one I just found on the web.eric123 said:Harley put out some K's with a hardtail...Not sure what exact models, but I believe they were the flat track models...KH or KHK maybe?
