Topic: Rear loop, How is it done?

[fr33man]

Hi again,
I'm starting a cafe conversion of my cb750f1 and was planing to make it as reverseable as possible but don't know how its done..

Do I need a rear loop and how much should I cut off the frame.. I've tried to search but haven't found anything that would ease my frustration.  Can you?

I figured out how far back I wanted the hoop to go, essentially 2/3 of the diameter of wheel when looking at the top, got 1" conduit pipe bend a 8.5" diameter loop on a tube bender, cut edges to match length. The hard part is bending it. Took me 5 tries an oxy-actelyne torch 2 people and a 5' extension on the bender to get a good fluid curve. I might still have 1 or 2 of my attempts if you want to buy one. Unless you have that equipment the proper shoes and dies with a big ass vice to adjust it to size I'd say buy one.

My question is not as much on how the loop is made but do I have to cut the frame? Should I remove the "bridge" holding the mudguard and so on ü

When doing anything allow enough room for the tyre when the suspension bottoms out.  There was one member on here who nearly had a very bad day about 6 months ago when his rear tyre bottomed out on his seat.

To answer your earlier question, no you really don't need a rear hoop. It's cosmetic thing . That "u" piece that the mudguard fastens to is a structural support. If you decide to weld in a hoop, that "u" piece is cut out. Personally, I would weld in a temporary steel brace before cutting out the "u". Then weld in the hoop and cut the temporary brace out. Also, as mentioned before, a hoop will generally interfere with the suspension travel . Many would use a kicked up hoop in this case , giving you the proper clearance. Or, some use longer rear shocks, which will change how the bike handles. If your rear bottoming out is a concern of yours, definately measure your rear suspension travel before cutting anything. Then do your fabrication work.

If you want it as reversible as possible don't cut the frame at all.
Hoopz are not necessary to be considered 'cafemetized'.
