Thanks for all the advice, and the link to Laamseats.com. But I have decided to go for a Russell.
I guess it looks like Vinyl then
Things are on the move bought a secondhand BMW R1200 RT seat off eBay today. It’s a BMW high seat but that should not be a problem as I ride with the standard seat on the high position + an air hawk and sheepskin. I can set the new high seat in the low position and there will only be about 5mm height difference in height. Now I can check out what height seat suits me best and use that seat as the donor seat for the Russell day long,
