Riding season here in Finland is nearing the end and I had to have something to fiddle. My SF 1098 has an Ilmberger carbon rear seat cover and wife has her own bike. I have no intentions to ride the SF two up so the rear pegs had to go.
There are several exhaust hangers for sale. The DP carbon one is really expensive plus I do not like the weird kinked dog leg shape. Almost all others are alu plate cut outs with edges machined and then bent to shape. Imho they do not look right with the trellis frame and a bit cheap actually. I have never seen the Shift tech one live but it looks better.
So the hanger had to be made of steel tube to match the frame and nature of a traditional Ducati. Aluminum might not be strong enough plus the welds would look crude. Make tiny and neat welds and it will crack. So steel it had to be. 316L austenitic that is. I am a machining supervisor in process industry so stainless and acid proof steels are everyday bread.
First I had to make a jig using the original rear peg bracket/exhaust hanger to make sure the fixing points are correct with first try.
I modeled the fixing stubs and exhaust can hanger ring with Autodesk Inventor and made the drawings for the machinist. The I bolted the parts to the jig and cut the 12mm 316L seamless tubes to fit.
Making a good fit is a pain because nothing is straight edge or centered with this hanger. One tube was scrapped. A friend of mine welded the tubes. He used to weld boat railings for his living so he is a TIG master for sure.
The hanger fit like a glove first try. Next step is to have it sandblasted and I will paint it flat black to match the frame.
