I have found a ton of videos that show building cafe racer seats out of foam blocks and fiberglass, but I haven't found one that actually shows how they are being mounted. If you guys know of a good video, please post the link or redirect me here to another thread. Thanks for the help guys.

Best advise i can give you for a structure like a seat frame, is to start with a fabricated steel pan frame. The frame itself doesnt need to be extensive but having a steel base framework allows you to mount structural tabs or other forms of mounting to its structure easily for bolting it to an existing mount or a custom made mount on the bike itself.. The steel base also gives you a strong platform to build off of, if you were attempting to lay fiberglass.
Some people just lay forms of card and waxed paper over their bike frames to mould a fitted fiberglass pan without steel. You would probably need some heavy glass for it to be structural and not crack paint when you sit on it though.. Going the straight glass route you can epoxy threaded steel nuts into layers of the media and bolt from inside the frames via drilled holes or custom mounting.
There are a hundred way to get it done. Its all about picking a path that best suits your abilities. I tend to go more structural and less crafty but you can do dome real neat stuff if you go the extra length to hide hardware and smooth things out real good -
What "works" is going to depend on the bike. For example, what "works" on a Yamaha is not necessarily going to work on a GS.

-Dime City Cycle "How to mount a cafe seat" is one way with marine grade materials while using bulky plastic blocks clamping it to the frame.Originally posted by ruler7171 View Post
-You can use any material you feel fit and then glass it to be waterproof and stronger.
-depending on height and pitch of the glass cowl, You can drill right into the cross bars, mount the "mount" and then measure, drill, and mount the cowl and seat pan.
Glass cracks easily so be sure there are no stress points on the cowl.
Good luck and have fun!Comment
