Just had my longest day on my XR yesterday. Standard seat and standard suspension. The bike has done 2000 miles now and I would say that both the seat and suspension are a lot more compliant than they were from new. I'm now not even looking for a more comfortable seat. Bear in mind when you're testing seats that the clothing you wear has a huge influence on comfort. I wear underwear with no seams, linen trousers then textile motorcycle gear.
I was on the bike from 07.55 to 20.45 and did 428 miles round trip from home to a place called Applecross in bonnie Scotland. Roads are rural A roads and plenty single track B roads with passing places. Temperature was between 10 and 12degC and it rained for about a third of the day so that was interesting too. It's a great bike even without the rider mode option which I don't have. Mine has cruise, heated grips, handguards, Satnav (lifted to above the dash by a Givi mount), centre stand, quick-shift. I added a big sensible front mudguard that works a treat (see my post elsewhere on this forum). Have not yet organised a rear guard to stop the back of my topbox and heels being sprayed with crud.
The bodywork does a perfect job of making a calm air bubble for the rider except for tops of shoulders and helmet. I have the standard (not sports) screen and usually leave it down until the rain comes on.
For those of you looking for something lower and lighter than a gs I would wholeheartedly recommend an XR. The standard Road mode and standard suspension are perfectly good for what I need too.
