I'm installing them 22 May or so and will report them after a few days experience and adjustments. I hear you on standing up but many times, secondary roads or not, on a long haul the speed doesn't allow for this option. What I'm looking for is a 10% of the ride option to uncoil my legs. We'll see.....
Question added: Should I be comfortable standing up at 50mph? What speed is considered max for stand-up?
I agree being able to stretch out for even a couple of minutes is very desirable and certainly an option I intend to pursue, I just don't see a location that works for my long legs and with the Touratech engine bars I have, further investigation is needed.
As for standing up, it's not something I'm ever totally happy doing, I'm always conscious as to potentially how easily a foot could come off the peg, so speed wise it's usually pretty low for me, like when you go into a low speed limit, 25-30 or if I'm in the middle of nowhere I just slow down or do it while I'm waiting for someone to catch up. I find on the times I feel really uncomfortable on the bike and just have to stretch standing for even 20 or 30 seconds brings relief when no one else is stopping and it's only a few more miles to a destination.
Even on my R1100r I find that because the Ilium pegs have my knees rather high, I don't feel as safe as in the normal riding position and with having my feet away from the controls, so there was an adjustment there in terms of wanting to ride for more than a few moments with my legs forward. It got better with time, but it still gives me the feeling of being on top of the bike, rather than being part of it.
I'll be interested to see your results, the Ilium Works peg a certainly a product that has a very upmarket feel and quality that made me feel much happier about bolting them on, compared to other options I've seen.
