Hey guys looking for ideas to mount a thruxton style seat on my cb750. I'm out of ideas and my imagination isn't very good. All help is greatly appreciated. Thanks!
Without seeing the bottom of the seat I can't give specifics, but on my 750 I ended up drilling some holes in the frame brace that sits right under yer balls and the one under the crack of yer ass and running carraige bolts through them with nuts and washers securing it down. It's not that difficult to get to the nuts to loosen them and remove the seat. You could also get a set of stock top hinges for your bike and rivet(or otherwise fasten) them to the thruxton seat bottom... Or you could go super low tech and attatch it using stick on velcro if it sits pretty flush and tight over the frame. I've also got a few more ideas that are a bit more difficult to articulate. But you get the point dude, it's not rocket sciencstry. Sit and look at it for a while and something will happen... Or legs will go to sleep...
looks like that, the underside is hollow. Unfortunately it sits on top of the rails so I think the velcro is out. I will prolly just have to screw it to the frame I guess.
those are just abs plastic, so nothing structural, imagine sitting on tupperware, basically the same. make sure it's sitting flat on the frame, or glue it to your old seatpan
Ditto the thread inserts. You can get a tool from Harbor Freight that works like a rivet gun and inserts a threaded rivet into the pan then you can fasten it down with machine screws.
I just built up a sub frame out of square tubing and bolted the seat to that and then the sub frame to the bike. I bought one of those abs plastic seats and its pretty rigid, but i would re-enforce it at least bit.
It isn't the prettiest way, but I just bent some galvanized strap over the rails and bolted it on. Then I epoxied some carriage bolts to the seat pan in line with the holes in the strap and use wing nuts to hold it in place. The wing nuts might even be unnecessary. Total cost around $3.
Of course if your seat doesn't cover the rails, you won't want to go this route because the strap would be visible. The other ideas are probably better in that case.
