Topic: Completing a Cafe Seat

[Sweep]

Hello, I've been out of it a while and now I'm trying to complete my cb750 cafe.

I have a square backed carpy seat I got from ebay and I really like the look of it.  I've got to figure out a secure way to mount it onto the frame, probably by creating one or two braces to bridge the frame tubes. 

My big concern is a seat cushion and cover.  Here's what I'm thinking of doing and I was hoping someone would correct me if I'm off.  I was going to create a secondary seat pan to lay on the seating surface of the pan that would be removable.  This piece would be covered and I would attach it with velcro.  Sound ok?

Thanks.

heck... why not just velcro your ass to the seat pan!      if its good enuf for NASA its good enuf for SOHC4, right? 

jk... square carpy seat?

I think airtech has a seat pan like that to upholster and attach to their seats.

Heh.  I'll attach a pic tomorrow.

I saw the airtech pan but I'm not sure if it will fit on my seat.  I'm sure I can make one easily enough and I'd really rather work with what I have, it's a well made piece and I like the look of it.

What you need to attach your seat easily to the frame and to keep your seat fully functional is my adjustable hinge kit.
stainless or black powdercoated steel. Instead of pinched, now laser cuted and same measurements like the stock hinges.

I took square tubing (4 pieces 3" long) and creased one side face of the tube with a punch and hammer.  This created a V which fit over the frame round tubing.  I made sure the 4 square tube pieces where planar on the top.  Welded the tubes to the frame.  Drilled a hole in the fairing such that they were centered over the tubing.  Cardboard template helps.  Match drill or transfer the holes from the fairing to the 4 tubes welded to the frame.  Once you have the holes in the tubes, I attached nutplates inside the tubing.  My seat is just velcro'd to the fairing.  Add extra adhesive and staple the strips down.  4 screws hold the fairing on.  I have a trickle charger cable attached to the battery and coiled up and secured to the frame when not needed.  I don't need to take it off too much then.

I made a seat pan from plywood.  I worked at an aircraft company and managed to get a guy from the interiors department to add the foam and cover it.
