If you run DP at the Command prompt, you can enter the inner and outer diameters of the pipe. If you run this command from the menu, the diameter values are supplied for you.
The routine creates some default layers and colors that you can easily modify for your needs. CAD Management. CAD Tips Links.

The tricky thing may be creating pipe profile circle on different UCS you defined. GrantsPirate Piping and Mech.
Designer Always save a copy of the drawing before trying anything suggested here. Start PLINE command and snap to the endpoints from the outer part of the handle bar to the intersection to the mid point of the next section. Fillet that pline. Set UCS with the above method for the other intersection and the outer endpoints of the two lines forming the intersection. Use PLINE again, snap to the endp of the first pline, to the intersection to the middle of the center section of the handlebar.
Draw two circles of the correct diameter, doesn't matter the orientation of them. Use sweep for one circle and the first pline, repeat. Now mirror the two pieces and join if desired. First, select all your lines and change the thickness to 0. The lines will display better and I see no reason for the thickness. There's no need to create any UCS's.
Just create two 3dpoly's with 3 vertices the cyan segments in the image below and a polyline for the red segment I exploded your lines and joined the 2 arcs and straight line. Create one circle with a diameter equal to the diameter of the tubing. Give the sweep command 3 times picking first the circle then one of the 3 segments. Yes the red segments need to be on a plane but it need not be "horizontal". The circle and the polyline may each be at any 3D orientation for the sweep command to function.
If you want to fillet the arms you may have to change UCS then you will be able to trim and draw arcs fillets. In the screencast below I start with your line and arc 3D drawing of the handlebar centerline. Since the handlebars are symmetric only one half is splined with the intent of using 3dmirror to complete the model.
I start by setting osnap to end, nearest and node for the point of symmetry. I typically like to start creating splines with the fit method knowing I will manipulate the CVs to get the final shape I want.
Note that splinedit e edit vertex steps you through each "next" n CV or "previous" p CV at which point you can move m or add a CV a. When creating the spline you can specify the tangent vector. It is handy to have a line to reference when doing so. If you want to control the end tangency vector after you create the spline simply move the CV before the end CV to specify the direction of the tangent vector.
At in the screencast I create a construction line to reference when moving the nearby CV to make sure it is on the desired plane. I created the the path for two pieces and then used union to join the bars. UCS allows you to align to the separate sections to create the bends. This would be similar to taking the bar, bending it and then rotating the assembly and bending it again. See screencast. Simplest way, I think: I broke the mid-cross-bar part at its midpoint to work with half of the thing [left] for the first few steps.
The reason for Exploding the Polylines and making the pieces just Lines -- you can't Fillet a Polyline with a Line that's not in the Polyline's plane, so for this Fillet, you don't want the midway piece and adjacent arc connected to the next one as a Polyline.
So you can skip the changing-the-UCS-and-back parts of the above.
