Hi. I’m in the USA travelling, and have rented a GS. The bike which turned up was a fairly high mileage R1250GS Rallye. It’s a great bike, but I don’t see a lot of difference between my own R1200GS with the exception of it being a little tougher in the corners. The big difference is the rear brake. The rear brake on my GS is fairly spongy, it slows the bike down a bit but honestly it’s a bit crap, which I expect. The rear brake on the Rallye is great - immediate feel and stopping power. I realise that the Rallye is a bit more off road speced, but are the brakes upgraded also? Both have Brembo callipers. Cheers.
