The standard PR5 is good enough, for me anyway.

Guys,

I have about 10K on a set of Road5s.  I too was anxious to see the GT version out, but for whatever reason M is moving slowly.  At any rate, the standard PR5 is working well for me.  I know that load rating is the issue with the non-GT version.  For the 10K miles so far this summer it has been 30% high speed interstate, 40% normal city roads and inner city highways (rough roads in Seattle area) and 30% hauling ass on curvy blacktop in hot weather.

They have performed as well as I can recall the PR4GTs ever did. I ride single, 150#, ~22# in the each saddle bag, ~15# in the top case for a total of 209lbs. at all times.  On a recent trip to Laguna Seca I had an extra 30# on the back seat making it about 240 lbs. total.

I would not hesitate to get another set of PR5s when needed in lieu of the GT version.

Safe Riding!

  I know that load rating is the issue with the non-GT version. 

I'm no tire expert, but IIRC the Michelin tire guy (Eric Miller) said that in the case of the PR4 that the GT version has the exact same load rating as that of the non GT version. He said that the GT version is just stiffer. He also said that the perfect tire for the Concours14 currently is the PR4GT not the PR5. He kept referring to frame stiffness, I didn't ask but I was thinking he meant suspension stiffness? He indicated that the sport bikes have the stiffest frames so they have the most compliant tires, touring bikes have less compliant tires and that dirt bikes have the least compliant tires. Again I was thinking that he really meant suspension not frame stiffness, but then that could be just me not wishing to think that my C14 frame isn't stiff? I also don't think of dirt tires as stiff but then they are usually at lower pressures so perhaps he was referring to the tires natural sidewall stiffness at zero pressure. He seemed to think that most would find that the PR5 on a touring bike would double up on the cushioning between the suspension and the compliance of the tire it would feel...squirmy?...I think he said squirmy..might have been squirrely or mushy. (all those tech terms sound the same to me  ::) )

Regardless as to whether I heard correctly or misunderstood what he was trying to convey...The PR4: PR4GT; and the PR5 50/series rears all have the same weight speed rating 73W (270KPH @ 365 kg or 167.77 mph @ 804.6 lbs) and the 55/series rears all are all 75W (167.77 mph @ 853.18 lbs). Again I'm no tire* expert, but I'd be surprised if the PR5GT came out with a different load rating than the others respective to aspect ratio. (in other words 73W 50/series and 75w 55/series)

*to be totally too honest, I'm not really an expert in anything yet (and considering my age it's not likely to happen, ever.), but I'm getting pretty good at looking up useless crap on the internet.  :o

At your age you're probably not an expert on stiffness either. 
Thank God for good men willing to do extreme violence.

Road 5 GTs now available in the UK and most of the rest of Europe.
Look at the following, scroll down, and note the (GT) after some sizes, including the late model C10 front, both C14 sizes and the C14 55 series rear.

From what I see here the GTs are not yet available in the USA though.
