Customization for bikes

I want to be able to adjust the bike settings instead of being maxed out I want to be able to downgrade for courses based upon my bike… I said this many months ago… Please integrate that into the game. I might have bike seven, but I want to D tune it for the course… Please add that

Use bike 6. You will never see an option to remove parts or downgrade a bike. Learn how to let off the gas once in awhile.
