The concept of the hydraulic fork was first present on the Harley-Davidson Hydra Glide in 1949. Springer fork designs were around longer before the hydraulic fork. It's not a case of which came first, the chicken or the egg. There are basically two types of motorcycles forks: Springer and hydraulic forks. Or you can build your own springer front end. The design may be found under many different branding such as Wyatt Gatling, Road Max, Mid-USA, and tons of others. Most people just think of Springer front ends as a brand name of forks. You've heard about Springer forks since the first time you ever saw or heard about motorcycles.
