Not necessarily. Just think of a shopping cart wheel. It has negative rake and is very stable as a result. A shopping cart wheel that is turned around to effectively have "positive rake" will be very unstable in that state, i.e. it will tend to want to stop rolling straight and swing back around. Now consider a bike with a 90 degree head tube. What will be more stable, a negative rake or positive raked fork?
More positive rake=less trail=less stability/ more twitch.
There could be something I'm missing here and I will be grateful if someone points it out.
