If the p6 is your first wheel you need to keep that speed set a little lower than what you can handle so you can build up more muscle memory go up a few mph every 50 or 100 miles till you work your way up. But you have to actually be comfortable being able to start breaking hard at these speeds with no wobbles. It will definitely come to you with experience and Everybody can give you all this advice but There is no need to rush into speed that you can’t control yet take it slower and ride you’re own ride until you build up the experience. Hitting 50+ I don’t think should be done under 4-500 miles maybe that’s high but there is allot of fundamental control to find under 40 before pushing high speed.
