Came across this bike. I believe it was from the Oakland Roadster Show. Looks like the coolant is in the frame or the radiator is on the bottom.
Personally, Donald, I like the "lines" of yours more. The show bike looks nice, but it doesn't flow very well. Not to my middle-aged eyes, anyway. Maybe if it had less rake; it's not too bad from the tank on back.
I think you are right about the rake. Mine is 42º and 49º is the maximum to be drivable. Basically this is what i have learned over the years. When you look at the side view of the motorcycle you get the best look if the amount of rake is equal to the slope of the frame going towards the rear. so the length of the frame and how high it is at the front needs to fit with the amount of rake. i will post a good example. See what i mean? The length of the forks has to do with how high the front of the frame is from the ground. You could have two bikes with the same rake and one would have very long forks and one would have much shorter forks.
