Yes, it is, because it's harder to get primer/surfacer to stick to bare metal than it is to get it to stick to existing, sanded factory primer.
Only things I would add would be to not just sand between coats, but wetsand (have a slow-running garden hose over your work as you sand; feathers better that way), and start with 320 for the primer coat and use 600 for your color coats.
Also, when shooting your clear, you may notice that it's a challenge to apply it smoothly. When you shoot one side of the frame, the other side of the tubing, and the rest of the frame, gets a lot of overspray, which will lead to a dimpled, or 'orange-peel' effect. It drove me nuts the first few times I painted frames. You will need to work fairly quickly to avoid this.
