You want some kind of suspension. Something is going to give over bumps and it shouldnt be solid forks' or frame's structure. I have a micargi stretch something or other with solid triple trees that went up or down a curb at stupid low speeds and bent the forks. I've been running the forks that came with the F-Zero for several thousand miles now and don't have any complaints other than it sucks for a suspension fork. I've hit stuff in the dark that sent me airborne going 40+ a few times and they still ride straight and feel ok. I've been interested in the Zoom Downhill Forks off Amazon but have not bought them yet because my TIG welder is DC only and I have a headlight and dual front brakes that I would like to keep. The Zoom forks are super tall and adjustable so you can play with your stance. The forks I am running are not adjustable height.
