I've been reading several threads about fork swaps and there is always a part when they talk about the trail or rake being changed or making sure that it doesn't. This is where my inexperience and general ignorance of motorcycle geometry comes into play.
As I understand it, the angle of the forks to the ground gives us the rake. And the angle of the forks combined with the height of the axle is what determines the trail. Am I correct so far? If so, then wouldn't the rake be determined by the angle of the head where the yoke/triple tree mounts? And then the trail would be determined by the length of the forks that are used. Correct?
As a side note, it appears as though it is always the same forks that are used. RC51, f4i, or R1. What about other models that have inverted forks? The FZ1 has them as do Suzuki TL1000R's.
Basically I am just curious about the basics. Thanks all!
