I saw somewhere that people were selling quick disconnect seat pins, which makes a ton of sense to me. But they had been discontinued. I can't find the page. Does anyone know why they were discontinued by whoever was selling them? I'd assume it's a safety issue, but wondered if there were any other solutions.

I think the S40 are M6 x 1.0 thread. Would a triumph use that thread? It's not listed in the specs.

Thanks, yea. I think 6mm is the outside thread diameter - M6

1.5" or 35mm is the length of the threads

M6 x 1.0 means 6mm outside diameter, 1.0mm per thread twist which is standard for M6.

So the triumph would be M6 x 1.0 x 35mm and should work.

All the triumphs I can find though have stupid long heads and are $30/pair shipped. I'm not spending $60 on these.

I'll update once I figure out a good solution.

Edit: new Bonneville link above is $42 shipped for me

Yea I did the M6 hex, but added a washer and lock washer to keep it from vibrating loose. I keep dropping them and the allen wrenches doesn't fit well behind the rear seat back/rack.

If I could get the locking push pins would you want those?
