Looking for a solo sprung seat

Postby cmattina » Sun May 10, 2020 4:09 pm

Looking for a seat as well as the front bracket.

Otherwise, looks like ill be pulling the trigger on a repro lycette. Drags says the front brack is not available on those after market seats... do people usually make their own? can they be put on the aftermarket seat?

The brackets are not hard to fabricate - I used 3mm mild steel for these ones on my VH. I also found that I needed small brackets on the rear to line-up the springs with the frame mounting points.

Several factors to consider:
The petrol tank needs to be in place so that you can judge how the nose of the seat will clear the rear tank cutout and possibly how much top clearance is required.
You need the correct length main springs with the correct seat posts.
The springs need to be plumb both side to side and front to back. You may have to drill new holes in the seat frame and or make new attachment brackets to set the nose back from the tank.
Above all, the seat needs to be level and the springs not leaning either way. The springs can be turned in place to help plumb.
Once the back end is figured, you can fashion the front brackets. Try mockups using cardboard or light aluminum. If you don’t have a proper press, the final brackets can be formed in a vice using a torch to help make the bends.
Every fit up varies slightly.

Do the aftermarket lycette style seats take a brake? In the picture above, is the an original seat or aftermarket?

It's a Wassell large universal seat. W-950 is the part number I think.

As Wade says the brackets need to be made to suit your tank and frame. I made trial brackets out of 3mm hardboard to get the correct spacing for the petrol tank. I also made two small flat brackets at the rear to keep the springs vertical.

Don't forget that the seats used on the SQ4 are much larger and have the raised rear.
