So far no issues with the Tourance EXP on my R1200GS (09).
I really enjoy those tires. Have in mind that I am almost 130Kgr and 1.97m height and I use to corner allot. So far I placed 4.300Km on the pair of EXPs and they behave very well.
They behave fine even with two-up at a total payload of 225Kg on my little elephant (I mean my GS).
The only bad thing is that they make allot of noise while spinning after 65Km/Hr. The noise comes from the crown of the tires and not for the profile, I checked it because when on the crown I get a wobbling deep noise and when cornering noise goes off…..that’s the only reason keeping me away from re-install them, apart from that is a nice type of tire that goes fine with the on-off nature of a GS.
