You mean Harley inspired fork gaiters, they have been using them for a while, this is a 1952 K model that led to the Sportster series. At that time I think Triumph was still using the steel "beer can" fork covers (you know like the ones on Harleys) and used them up till the early sixties. I think Triumph used the beer cans first but I could be wrong. The original Sportster, the 1957 had them too and I think they were a factory accessory for many years. I'm not trying to be a know-it-all (please correct me if I'm wrong) but it is an interesting bit of history, at least it is to me.Love the Triumph inspired fork gaiters. Nice touch.
