The CB550 is gonna have carry two up on a regular basis so no café seats here. This posed it's own problems from a stylistic point of view. Dual seats have a tendency to look bulky on any bike so I wanted to achieve a fairly flat, thin look without going the uncomfortable brat-style route. Here's the process...
Firstly the original seat was completely stripped so that the pan could be used as a guide for holes, studs etc. The original was in very poor condition.
The frame brace in the first shot is what causes the original seat to rise so dramatically so it was chopped and a new, much lower bracket was formed. This still needs to be finished and painted as it is going to serve a few more purposes yet.
Based loosely on the measurements of the original but modified to meet the new spec, a cardboard template was made.
This was then translated into 20 gauge mild steel.
Separate pieces were fabricated to fill the gaps created during bending and to add some shape.
Then she went under the welding torch. Fully TIG welded with all holes drilled and studs tacked in it's ready for the final stage...
Paint! A nice powder coat of satin black.
And it's off to the upholsterers on Monday. Stay tuned!
